The National Weather Service in Fort Worth has issued a Flash Flood Warning for Central Grayson County in north central Texas, in effect until 8:45 PM CDT tonight (Sunday, September 20). At 6:18 PM CDT, emergency management reported multiple flooded roads and vehicles stuck in flood water in and around the Denison area — flash flooding is already occurring, with additional instances imminent or occurring in the Sherman to Southmayd areas as well.

Vehicles stuck in flood water during the warning window means water is moving through the built environment, not just the creeks — exactly the kind of event that fills restoration schedules for a week. For contractors across the Sherman–Denison–Southmayd corridor, tonight’s job pipeline is interior water intrusion, saturated building materials, and the mold clock that starts the moment water sits. This is a live snapshot as of 6:40 PM CDT. Conditions change fast — always verify with the National Weather Service for your specific county or ZIP code.

Central Grayson County — Flash Flood Warning

Issuing office: NWS Fort Worth TX · Issued: 6:18 PM CDT, September 20, 2026 · Expires: 8:45 PM CDT, September 20, 2026

Hazard, verbatim from the alert: Flash flooding caused by thunderstorms.

Source: Emergency management reported.

At 6:18 PM CDT, emergency management reported multiple flooded roads and vehicles stuck in flood water in and around the Denison area. Flash flooding is already occurring in this area. Additional instances of flash flooding are imminent or occurring in the Sherman to Southmayd areas as well.

Expected impact: Flash flooding of small creeks and streams, urban areas, highways, streets and underpasses as well as other poor drainage and low-lying areas.

Locations that will experience flash flooding include: Sherman, Denison, Pottsboro, Knollwood, Randell Lake, Eisenhower State Park, Southmayd, Boddie and Carpenters Bluff.

This is a ground-truth warning: emergency managers, not models, are reporting flooded roads and stranded vehicles. Track the Fort Worth office page (weather.gov/fwd) for the next update; the authoritative alert source is the NWS API record (alert link).

Stay safe tonight

Turn around, don’t drown. The NWS instruction for this warning is direct: when encountering flooded roads, turn around — most flood deaths occur in vehicles. With vehicles already reported stuck in flood water around Denison, treat every water-covered road as deeper and faster than it looks.

If water enters your home: stay out of standing water anywhere electricity may be present, and avoid the basement until the water recedes and power is confirmed off. Photograph everything before cleanup starts — that photo set is the evidence the insurance process runs on. Then call a local restoration contractor. Sitting water starts a second wave of damage within a day: wicking drywall, swollen trim and subfloor, and microbial growth in any cavity that stays damp.

Poor-drainage and low-lying areas are called out by name in this warning — if your property sits low near a creek, stream, or known ponding street, check it now rather than in the morning. Eisenhower State Park campers and lake-adjacent residents near Randell Lake should be alert to rapidly rising water.

What this means for restoration teams

A flash flood warning where the source report is “vehicles stuck in flood water” is a leading indicator for structural water work. Expect the full spread across Central Grayson County:

• Interior water intrusion in low-lying residential and commercial buildings — Denison’s flooded roads mean water was at or above curb level, which puts ground-floor entries, garages, and slab-on-grade rooms in the splash zone.
• Saturated drywall, insulation, and flooring — any material in the waterline footprint needs a moisture reading, not a fingertip test.
• Mold risk within 24–48 hours for anything that stays damp through the night.
• Sewage backup in low-lying areas where the drainage system is overwhelmed — a health hazard that changes the PPE and disposal protocol on the job.
• Park and lakeside exposure around Eisenhower State Park and Randell Lake: campgrounds, cabins, and lakeside structures that see sheet-flow flooding fast.

The play: stage equipment now. Pre-position extraction, air movers, and dehumidifiers; keep the on-call rotation through the night and into Monday morning — discovery calls lag the water by hours to days. On the first call, capture address, water source, and affected areas up front. For sewage-backup flags, ask before you roll so the crew brings the right protocol.

Field discipline: photo-document before mitigation, moisture-map every affected room, and keep payment responsibility in writing before work starts. The Denison jobs you document cleanly tonight are the adjuster-approved jobs next week.

FEMA & federal assistance

If flood damage hits your home and you need federal help: the FEMA Helpline is 1-800-621-3362 (7 a.m.–10 p.m. local time, 7 days a week). Apply at DisasterAssistance.gov, through the FEMA app, or locate recovery centers at fema.gov/drc.

Basic eligibility: U.S. citizenship or qualified immigration status, identity verification, proof of occupancy or ownership, and unmet needs not covered by insurance. Apply as soon as it is safe — and start the documentation (photos, receipts, contractor invoices) the moment the water is out.

Looking ahead

This warning runs until 8:45 PM CDT tonight. Small creeks and streams are the overnight variable: they can crest after the rain ends, and ground already saturated from the first round floods faster if a second round moves through. The NWS Fort Worth office will cycle updates through the evening — and a separate Flash Flood Warning for East Central Grayson County (until 8:00 PM CDT) is running in parallel over the same storm complex, so treat the whole Sherman–Denison area as one active event.

For contractors, the demand window note: water-intrusion calls typically start within hours of the water receding and keep coming for days as people discover what’s behind the baseboards and under the flooring. The job that looks like “damp carpet” on Monday is the full-room remediation on Thursday if the pad stayed wet.

The National Weather Service in Fort Worth has issued a Flash Flood Warning for East Central Grayson County in north central Texas, in effect until 8:00 PM CDT tonight (Sunday, September 20). At 6:27 PM CDT, emergency management reported multiple un-passable roads and potential water rescues ongoing in Denison — flash flooding is happening now or will begin shortly.

For restoration teams in the Sherman–Denison corridor, this is the exact scenario that turns into interior flooding jobs: life-threatening flash flooding of urban areas, highways, streets, and underpasses. This is a live snapshot as of 6:40 PM CDT. Conditions change fast — always verify with the National Weather Service for your specific county or ZIP code.

East Central Grayson County — Flash Flood Warning

Issuing office: NWS Fort Worth TX · Issued: 6:27 PM CDT, September 20, 2026 · Expires: 8:00 PM CDT, September 20, 2026

Hazard, verbatim from the alert: Life threatening flash flooding.

Source: Emergency management reported.

At 6:27 PM CDT, emergency management reported multiple un-passable roads and potential water rescues ongoing in Denison. Flash flooding is ongoing or expected to begin shortly. Residents are told to stay off the roads unless absolutely necessary.

Expected impact: Life threatening flash flooding of creeks and streams, urban areas, highways, streets and underpasses.

Locations that will experience flash flooding include: Sherman, Denison, Knollwood and Randell Lake.

The alert is a public-safety trigger, not a forecast refinement — this is radar-plus-ground-truth: emergency managers on the ground in Denison are reporting water over roads and rescues underway. Follow the Fort Worth office page (weather.gov/fwd) for updates; the authoritative alert source is the NWS API record for this warning (alert link).

Stay safe tonight

Turn around, don’t drown. The NWS warning states it plainly, and it’s worth repeating: when encountering flooded roads, turn around — most flood deaths occur in vehicles. Be aware of your surroundings and do not drive on flooded roads.

If water gets into your home: stay out of standing water anywhere electricity may be present, and avoid the basement until the water recedes and power is confirmed off. Before any cleanup begins, photograph everything — documentation is what the insurance conversation stands on. Then call a local restoration contractor. Water left sitting starts a second wave of damage within a day: saturated drywall, swollen subfloors, and microbial growth that a fan and a mop cannot stop.

If you are in Denison, Sherman, Knollwood, or near Randell Lake tonight, stay off the roads unless it is absolutely necessary. Water over a road hides washouts; six inches of moving water can knock you off your feet, and twelve inches can carry a car.

What this means for restoration teams

When emergency management is reporting water rescues in Denison during the warning window, water is already where it shouldn’t be — and that includes structures. For Grayson County contractors, tonight’s damage categories are the familiar ones:

• Interior water intrusion in low-lying homes and businesses along creeks, streams, and poor-drainage streets in the Denison–Sherman urban core.
• Saturated drywall and insulation — floodwater wicks upward fast; anything within the waterline footprint needs a moisture check, not a visual guess.
• Mold risk within 24–48 hours in any space that stays damp overnight.
• Sewage backup in low-lying areas, where overwhelmed drainage pushes wastewater back into ground-floor plumbing.
• Underpass and street-adjacent commercial damage — water pushed across highways and parking lots finds every slab joint and door threshold.

The play: stage equipment now. Pre-position air movers, dehumidifiers, and extraction units so the first call doesn’t burn an hour on logistics. Keep an on-call rotation through the night — water-intrusion calls don’t respect the warning’s expiry. On the first call, capture address, water source (rising exterior water vs. plumbing vs. seepage), and affected areas before you roll: the triage call is the claim’s foundation.

Field discipline: photo-document before mitigation starts, moisture-map every affected room (walls, subfloor, insulation cavities), and keep the homeowner’s payment responsibility clear in writing before work begins. The documentation habit you build tonight is what keeps the adjuster conversation clean next week.

FEMA & federal assistance

If the flooding damages your home and you need federal help, the standard channels apply: the FEMA Helpline is 1-800-621-3362 (7 a.m.–10 p.m. local time, 7 days a week). You can also apply at DisasterAssistance.gov, through the FEMA app, or find recovery centers at fema.gov/drc.

Basic eligibility: U.S. citizenship or qualified immigration status, identity verification, proof of occupancy or ownership, and unmet needs not covered by insurance. Apply as soon as it is safe to do so — federal assistance can cover what insurance doesn’t, but the documentation (photos, receipts, contractor invoices) starts the moment the water is out.

Looking ahead

This warning runs until 8:00 PM CDT tonight. When it expires, the danger doesn’t necessarily clock out with it — creeks and streams can crest after the rain stops, and saturated ground means any additional round tonight floods faster than the first.

Watch for the NWS Fort Worth office’s next update cycle and any new warnings for adjacent areas (a separate Flash Flood Warning is already active for Central Grayson County until 8:45 PM CDT — the same storm complex is working both zones). For contractors, the demand window note holds: water-intrusion calls typically start within hours of the water receding and keep coming for days as people discover damage behind walls and under floors. A Denison homeowner who thinks the carpet “feels dry” on Monday is a mold job by Wednesday if the pad underneath stayed wet.

The National Weather Service in Norman has issued a Flash Flood Warning for southwestern Bryan County in southeastern Oklahoma, in effect now through 8:45 PM CDT tonight (September 20). Doppler radar shows thunderstorms producing heavy rain across the warned area, with 1 to 3 inches already fallen and another 1 to 2 inches possible. Flash flooding is ongoing or expected to begin shortly — the exact interior-flooding scenario local restoration crews handle most. This is a live snapshot as of 6:18 PM CDT. Conditions change fast — always verify with the National Weather Service for your specific county or ZIP code.

Southwestern Bryan County — Flash Flood Warning

Issuing office: NWS Norman, Oklahoma (weather.gov/oun). Issued: 6:12 PM CDT, September 20, 2026. Expires: 8:45 PM CDT. Severity is rated Severe, certainty Likely, urgency Immediate — this is the high-confidence, act-now end of the flash flood spectrum.

Hazard detail, verbatim from the alert: Radar-indicated thunderstorms producing heavy rain. Between 1 and 3 inches of rain have fallen across the warned area, and additional rainfall amounts of 1 to 2 inches are possible. Flash flooding is ongoing or expected to begin shortly. This is a radar-indicated event — gauges may under-report what the radar is seeing, so trust the warning text over what the creek behind your house looks like right now.

Locations in the warning path: Durant, Colbert, Achille, Silo, Mead, Hendrix, Cartwright, eastern Lake Texoma, and Calera. If you are in or near any of these towns — or anywhere in southwestern Bryan County — you are inside the warned polygon.

Expected impacts (from the alert): flash flooding of small creeks and streams, urban areas, highways, streets, and underpasses, as well as other poor-drainage and low-lying areas. In this part of southeastern Oklahoma that means the tributaries feeding Lake Texoma and the Red River bottomland roads, plus any low-water crossing between the listed towns. Urban spots in Durant and Calera can pond up fast with 2 inches in an hour — storm drains can’t keep up with this rate of fall.

Stay safe tonight

Turn around, don’t drown. The National Weather Service’s top instruction on this warning: turn around, don’t drown when encountering flooded roads — most flood deaths occur in vehicles. It takes just six inches of fast-moving water to knock an adult off their feet, and twelve inches to sweep away a small car. Never drive through flooded roadways or around barricades; the roadbed beneath floodwater can be washed out even when the surface looks intact.

If water enters your home, stay out of standing water where electricity may be present — floodwater and live current are a lethal combination. Avoid the basement until water recedes and you can confirm the power is off. Photograph everything before cleanup starts; documentation matters for insurance, and adjusters work from what was captured in the moment, not what you describe later. Once it’s safe, call a local restoration contractor — water left sitting starts a second wave of damage within a day as drywall wicks upward, insulation saturates, and the mold clock starts ticking.

What this means for restoration teams

This warning converts directly into the damage categories southeastern Oklahoma contractors handle every storm season: interior water intrusion through slab edges and garage entries, saturated drywall and insulation at the base of walls, mold risk within 24–48 hours, and sewage backup in low-lying areas where lift stations and laterals get overwhelmed by inflow. Crews in Durant, Calera, and Colbert should treat the next several hours as a pre-positioning window, not a wait-and-see.

The play: stage equipment now — truck-mounts fueled, dehumidifiers and air movers loaded, desiccant drying assets pre-positioned so the first calls can roll within the hour. Keep an on-call rotation through the night and into Monday morning, because flash flood water-intrusion calls don’t all land at once; they arrive in waves as water recedes and people discover damage. Capture address, water source (rising groundwater vs. roof/window failure vs. sewer backup), and every affected area on the first call — that triage note is what keeps the job documented and billable later.

Field discipline for the weekend rush: photo-document everything before mitigation begins, moisture-map every affected room (meters, not eyes), and keep the homeowner’s payment responsibility clear in writing before work starts. On a Saturday-night flood event, the temptation is to start ripping and bill later — that’s how invoices get disputed in October. The contractors who come out clean are the ones who scoped it, signed it, then dried it.

FEMA & federal assistance

If the flooding damages your home, help is available through federal channels: the FEMA Helpline at 1-800-621-3362 (7 a.m.–10 p.m. local time, 7 days a week), DisasterAssistance.gov, the FEMA mobile app, and fema.gov/drc for disaster recovery center locations. Basic eligibility requires citizenship or qualified immigration status, identity verification, proof of occupancy or ownership, and unmet needs not covered by insurance. Apply as soon as it’s safe to do so — and keep that photo documentation from the safety section; it’s exactly what the application asks for.

Looking ahead

When this warning expires at 8:45 PM CDT, the rain may stop but the water story doesn’t. Creeks and tributaries in the Lake Texoma watershed can crest an hour or more after the heaviest rain ends, and urban drainage issues linger into the night. Watch for additional rounds — tonight’s atmosphere is loaded, and the NWS Norman office will update or extend as conditions evolve. The next official read on the situation will land through NWS Norman’s page and alert feed.

For contractors, the demand window typically opens within hours of water receding and keeps coming for days as people discover damage — the Monday-morning calls from homeowners who woke up to a wet garage are as real as the Sunday-night emergencies. Monday is a full workday for flood work in Bryan County.

For your protection move to an interior room on the lowest floor of a
building.

This storm is producing large hail. SEEK SHELTER NOW inside a sturdy
structure and stay away from windows.

Stay safe during the storm

Get inside a sturdy building and stay away from windows. Large hail can shatter glass and injure anyone caught outside; damaging winds can bring down trees and power lines with little warning.

If hail damages your home: photograph every slope of the roof, siding, gutters, and windows before anything is repaired — documentation matters for insurance. Then call a local roofing or restoration contractor for an inspection; hail bruising is not always visible from the ground.

What this means for restoration teams

Translate this warning into job tickets: hail-punched roofing (bruised shingles that fail months later if missed), cracked siding, shattered windows and skylights, dented gutters and downspouts, and damaged outdoor HVAC condensers. Water intrusion follows where hail compromised the envelope — the roofer’s repair and the restorer’s dry-out land on the same houses.

The play: coordinate with local roofers on inspection routes — hail jobs pair naturally with restoration drying work when water got in. Stage drying equipment for the intrusion calls, keep an on-call rotation, and capture address, hail size reported, and visible exterior damage on the first call. Field discipline: photo-document the roof from the ground and up close before repairs, and get payment responsibility in writing before work starts.

This storm is carrying golf ball size hail (1.75 inches) and 60 mph wind gusts, and the NWS impact statement names the damage explicitly: expect hail damage to roofs, siding, windows, and vehicles, and expect wind damage to roofs, siding, and trees. That is the exact damage profile restoration teams and roofing contractors see after a storm like this — the jobs start the same evening and keep coming for days.

Cheyenne, CO — Severe Thunderstorm Warning

• Issuing office: NWS Goodland KS
• Issued: 4:09 PM MDT, September 20, 2026
• Expires: 4:45 PM MDT, September 20, 2026
• Area: Cheyenne, Colorado — the warning covers northwestern Cheyenne County in east central Colorado
• Certainty: Observed  |  Urgency: Immediate

Where the storm is: At 4:08 PM MDT, the severe thunderstorm was located 11 miles east of Boyero, or 25 miles south of Flagler, moving southeast at 20 mph.

Hazard detail, verbatim from the NWS alert:

• Hail: golf ball size hail — 1.75 inches (hail threat: observed)
• Wind: 60 mph gusts (radar indicated)
• Thunderstorm damage threat: considerable

Impact, verbatim from the NWS alert: People and animals outdoors will be injured. Expect hail damage to roofs, siding, windows, and vehicles. Expect wind damage to roofs, siding, and trees.

Locations impacted include: Wild Horse and Aroya.

Source links: the NWS alert for this warning and the NWS Goodland office page.

Stay safe right now

Take the NWS instruction at face value: for your protection, move to an interior room on the lowest floor of a building. Golf ball size hail injures people and animals caught outdoors — get inside before the core arrives, not when it is overhead.

If you can move vehicles under cover safely, do it; the NWS expects hail damage to windows and vehicles in the storm path. After the storm passes, treat every downed line as live, give damaged trees a wide berth, and do not drive around barricades — runoff and debris can make rural county roads impassable even without a flash flood warning.

When the sky clears, photograph roof, siding, window, and vehicle damage before anything is touched. Timestamped photos are the foundation of an insurance claim, and hail bruising on shingles is easy to miss once debris is cleared. Then call a local contractor — water finding its way through hail-compromised roofing starts a second wave of interior damage within days.

What this means for restoration teams

This is a hail-first event with a wind kicker — 1.75-inch observed hail with a “considerable” damage threat and 60 mph gusts. The NWS impact wording maps directly to the work orders: roof and siding repair, window replacement, vehicle damage (auto glass and body shops feel it too), and wind damage to roofs, siding, and trees.

The damage categories to stage for:

• Roof systems: hail bruising and punctures in shingles, membrane damage on low-slope roofs, compromised flashing. This is the call driver — the NWS explicitly expects hail damage to roofs.
• Siding and windows: cracked vinyl, dented metal siding, broken glass from wind-driven hail.
• Interior water intrusion: anywhere hail or wind opened the building envelope, the next rain finishes the job. Saturated drywall and insulation, and mold risk within 24–48 hours if it stays wet.
• Tree and debris damage: 60 mph gusts bring limbs down onto roofs, fences, and vehicles — expect the odd emergency tarp and board-up call.

The play tonight: keep an on-call rotation through the evening, pre-position tarps and board-up materials, and pair with a roofer if you have one — hail events are the rare storm where the roofer and the restorer get called to the same address. On the first call, capture the address, the damage type (roof, siding, windows, interior water), and whether photos exist already.

Field discipline: photo-document before mitigation, moisture-map every affected room when water has entered, and keep the homeowner’s payment responsibility clear in writing before work starts.

FEMA & federal assistance

If this storm causes damage beyond what insurance covers, the FEMA Helpline is 1-800-621-3362 (7 a.m.–10 p.m. local time, 7 days a week). You can also apply at DisasterAssistance.gov, through the FEMA app, or find a recovery center at fema.gov/drc.

Basic eligibility: U.S. citizenship or qualified status, identity verification, proof of occupancy or ownership, and unmet needs not covered by insurance. Apply as soon as it is safe to do so.

Looking ahead

The warning expires at 4:45 PM MDT. The storm was moving southeast at 20 mph at last report, so the corridor around Wild Horse and Aroya should see the core pass through and then ease — but a warning this short (36 minutes from issuance to expiry) means the NWS saw a fast-moving, high-confidence threat. Watch for updates from NWS Goodland: severe-warned storms can be extended, re-issued, or followed by additional rounds as the line evolves.

Demand window: hail-damage calls typically start the same evening as homeowners walk their property and discover roof, siding, and window damage, and they keep coming for days as insurance adjusters schedule inspections. If your area took the core, tonight and tomorrow morning are the window.

Flash flooding is the deadliest thunderstorm hazard in the United States, and it moves faster than it looks. If you are in the warned area:

• Turn around, don’t drown — never drive through flooded roadways. Most flood deaths occur in vehicles, and as little as a foot of moving water can carry a car.
• Never walk through floodwater — it can hide downed power lines, open manholes, and contaminated runoff.
• If water enters your home: stay out of standing water where electricity may be present, avoid the basement until water recedes and power is confirmed off.
• Photograph everything before cleanup — documentation matters for insurance.
• Then call a local restoration contractor — water left sitting starts a second wave of damage within a day.
• Small creeks and streams in the warned area can rise within minutes of heavy rain; keep away from their banks tonight.

What this means for restoration teams

With 2.5 to 3.5 inches of rain already down and more on the way, this is exactly the interior-flooding scenario restoration teams in southeastern Georgia see most: water intrusion through thresholds and crawlspaces, saturated drywall and insulation on ground floors, sewage backup in low-lying areas, and vehicle flooding along highways and underpasses. The NWS’s impacted-area list — creeks, streams, urban areas, streets, underpasses, poor-drainage and low-lying areas — maps directly onto the damage categories contractors handle.

The play:

• Stage extraction and drying equipment now — with flooding ongoing or imminent, the intake clock starts when water recedes, not when it rains.
• Pre-position for the Cogdell area and the surrounding county roads where low-lying and poor-drainage flooding is most likely.
• Keep an on-call rotation through the night. Water-intrusion calls typically start within hours of water receding and keep coming for days as people discover damage.
• Capture on the first call: address, water source (rain intrusion, creek overflow, sewage backup), affected areas, and whether power is on or off in the affected space.
• Field discipline: photo-document before mitigation, moisture-map every affected room, and keep the homeowner’s payment responsibility clear in writing before work starts.
• Mold watch: saturated drywall and insulation become mold risks within 24–48 hours — this is the first job’s follow-up and the second job’s trigger.
• Contamination caution: floodwater in low-lying urban areas can carry sewage and chemicals — categorize the water type before any crew contact and brief homeowners on it.

Status: ACTIVE — live snapshot as of 2:47 PM PDT (3:47 PM MDT), Sunday, September 20, 2026. A Severe Thunderstorm Warning carrying a considerable damage threat and observed tennis-ball-size hail is in effect for northwestern Cheyenne County and southwestern Kit Carson County, Colorado until 4:45 PM MDT. This post is for informational purposes and is not an official weather warning — always follow instructions from local authorities and the National Weather Service.

Stay safe through the hail

Tennis-ball-size hail — about 2.5 inches — is the heavy end of the scale. It breaks windows, dents vehicles deeply, and can seriously injure anyone caught outdoors. If you are in the warned area:

• Move to an interior room on the lowest floor of a building, now.
• Stay away from windows and skylights — large hail can shatter them and drive glass inward.
• Bring pets indoors; move vehicles under cover only if you can do so quickly and safely.
• After the storm, photograph any hail damage to your roof, siding, windows, or vehicles before cleanup — documentation matters for insurance.
• Rural roads in the warned area may carry storm debris or accumulated hail — drive cautiously or stay put until the cell passes.

What this means for restoration teams

Observed 2.5-inch hail with a considerable damage threat in rural east central Colorado is the classic high-severity restoration event: the NWS explicitly expects hail damage to roofs, siding, windows, and vehicles, plus wind damage to roofs, siding, and trees. Rural corridors like the ones around Wild Horse, Aroya, and Boyero tend to have older roofing stock and more outbuildings — both take hail harder, and both get inspected later, so damage discovered days out still needs a paper trail.

The play:

• Stage tarping and board-up assets now — broken windows and skylights on farmsteads and rural homes are the highest-urgency first response.
• Plan inspection coverage for the Wild Horse–Aroya corridor and surrounding farm country. Rural hail work is route-heavy; batch inspections by road to keep crews efficient.
• Keep an on-call rotation through the evening. The first calls will be window and vehicle damage; roof reports follow as homeowners get on ladders.
• Capture on the first call: address, hail size witnessed, any broken windows or skylights, water entry, and outbuilding damage.
• Field discipline: photo-document before mitigation, note impact marks on every elevation and roofing plane, and keep the homeowner’s payment responsibility clear in writing before work starts.
• Wind + hail combo: 60 mph gusts compound the damage — check ridge caps, gutters, and tree limbs on roofs that took hail. Wind-driven rain through compromised envelopes starts mold risk within 24–48 hours.

This warning expires at 4:45 PM MDT. The storm is moving southeast at 20 mph through mainly rural areas — residents east of the current cell should watch the sky and keep a weather source open. NWS Goodland will issue updates or new warnings as the storm evolves.

Demand window note: hail inspection and emergency-repair calls typically start within an hour or two of the storm passing and keep coming for days as people spot damage. With observed tennis-ball hail, adjuster pipelines will be busy — contractors who document first and document well win the long tail of this event.

Status: ACTIVE — live snapshot as of 2:47 PM PDT (3:47 PM MDT), Sunday, September 20, 2026. A Severe Thunderstorm Warning with a considerable damage threat is in effect for east central Lincoln County, Colorado until 4:15 PM MDT. This post is for informational purposes and is not an official weather warning — always follow instructions from local authorities and the National Weather Service.

Severe Thunderstorm Warning: Lincoln County — issued by NWS Denver

The National Weather Service in Denver issued this warning at 3:41 PM MDT, and it is valid until 4:15 PM MDT.

• Area: East central Lincoln County in east central Colorado.
• Storm location: At 3:41 PM MDT, a severe thunderstorm was located 8 miles north of Boyero, or 29 miles southeast of Limon, moving southeast at 30 mph.
• Hazard: Two inch hail and 60 mph wind gusts.
• Source: Radar indicated.
• Damage threat: Considerable (per NWS parameters).
• Impact: People and animals outdoors will be injured. Expect hail damage to roofs, siding, windows, and vehicles. Expect wind damage to roofs, siding, and trees. Hail may accumulate on roadways causing hazardous travel.
• Locations impacted include: Boyero.

NWS instruction: “Anyone outdoors should move to shelter inside a well-built structure and stay away from windows. This storm is capable of producing dangerous hail and damaging winds.”

Alert source: NWS alert record. Issuing office: NWS Denver/Boulder.

Stay safe through the hail

Two-inch hail is the size of a hen’s egg — heavy enough to dent vehicles, break windows, and injure anyone caught outside. If you are in the warned area:

• Move inside a well-built structure now and stay away from windows.
• Bring pets indoors; move vehicles under cover if you can do so safely and quickly.
• After the storm, photograph any hail damage to your roof, siding, windows, or vehicles before cleanup — documentation matters for insurance.
• Watch for hail accumulation on roadways causing hazardous travel; drive with caution or wait it out.
• Do not walk through storm debris without sturdy footwear — wind can scatter sharp material.

What this means for restoration teams

This is the signature hail event restoration contractors build their week around: two-inch hail with a considerable damage threat and an explicit NWS callout of roof, siding, and window damage. In east central Colorado, this is exactly the interior-and-exterior damage pattern restoration teams handle — dented and punctured shingles, compromised siding, broken windows letting wind-driven rain inside, and vehicles that homeowners will ask about.

The play:

• Stage tarping and board-up assets now — the highest-value first response after a hail signature like this is stopping secondary water intrusion before the next round.
• Pre-position inspection crews for Limon, Boyero, and the surrounding rural corridors — hail work is inspection-heavy and the first 24 hours set the claims.
• Keep an on-call rotation through the evening. Hail calls keep coming as homeowners get home and see the damage; windshield and skylight reports arrive first, roof reports follow.
• Capture on the first call: address, where the hail hit, any broken windows or skylights, and whether water is entering the structure.
• Field discipline: photo-document before mitigation, note hail size and direction of impact on every elevation, and keep the homeowner’s payment responsibility clear in writing before work starts.
• Mold and water watch: where wind-driven rain got through broken openings, moisture can start working on drywall within a day — moisture-map every affected room.

This warning expires at 4:15 PM MDT. Storms like this can regenerate or reform on the back side of the line, so watch the evening sky and keep weather.gov open through dinnertime. The NWS issues updates and new warnings as storms evolve — a fresh warning can extend coverage if the cell holds together or new cells fire.

Demand window note: hail-inspection and roof-tarp calls typically start within an hour or two of the storm passing and keep coming for days as people spot damage. Adjuster pipelines lag further — the first week after a considerable-threat hail event is the busiest intake window of the year for shops in the warned area.
