  • Storm Updates: Ohio–Pennsylvania–Western New York Slight Risk, Kansas–Missouri Flood Pulse — Wednesday, September 9, 2026

    This is a live Wednesday snapshot of local storm-type events across the United States as of the afternoon of Wednesday, September 9, 2026. The organized pulse is east of yesterday’s Iowa–Nebraska corridor. A Storm Prediction Center Slight Risk of severe thunderstorms covers central Ohio into northwest Pennsylvania and western New York, and Severe Thunderstorm Watch 665 is in effect until 11:00 p.m. EDT. Farther west, the Weather Prediction Center holds a Slight Risk of excessive rainfall from southeast Kansas into south-central Missouri, with smaller flood-risk pockets in southeast Colorado and the Arizona–New Mexico border country.

    These are county- and ZIP-scale thunderstorms, not a mainland hurricane landfall. Restoration exposure tonight is wind-driven roof and siding work, trees on service drops, isolated hail, and interior water where cells train. Conditions change fast. Verify with the National Weather Service for the specific county or ZIP before you roll.

    What is live this afternoon

    Watch 665 covers western New York, northern Ohio, northwest Pennsylvania, the northern panhandle of West Virginia, and adjacent Lake Erie waters. Primary threat language is scattered damaging wind gusts to about 65 mph. SPC and NWS discussion also leaves room for a brief tornado, especially if a storm anchors on the surface boundary near the Ohio–Pennsylvania–New York border. Hail is secondary.

    A cold front still stretches on the order of a thousand miles from the Central Plains through the Great Lakes toward western New York. That is the same family of storms that wet Iowa and eastern Nebraska on Tuesday. Today the better-organized severe corridor is the eastern Great Lakes. Isolated strong-to-severe cells remain possible from the central Plains into the Ohio Valley, with a more disorganized, outflow-dominant mode west of the watch.

    Hotspot 1 — Northern Ohio, northwest Pennsylvania, western New York

    This is the live watch. Storms are expected to increase through late afternoon and evening in a warm, humid boundary layer with enough shear for organized multicells, short line segments, and transient supercells. Mesoscale discussion language from mid-afternoon: a few damaging gusts over the next few hours, brief tornado not ruled out.

    Cities and counties to watch: Cleveland, Akron, Canton, Parma, Mansfield, Lorain and Medina counties in Ohio; Erie, Crawford, Warren, Mercer, and neighboring northwest Pennsylvania counties; Chautauqua, Cattaraugus, and Allegany in western New York; the northern West Virginia panhandle.

    Restoration read: wind first. Stage tarps, generators, and tree crews before dark. If a cell trains or a warning includes heavy rain, treat the same ZIP as a water job by morning. Photograph roofs in remaining daylight only if it is safe.

    Hotspot 2 — Southeast Kansas into south-central Missouri, plus leftover Iowa water

    WPC’s Day 1 excessive-rainfall outlook keeps a Slight Risk from southeast Kansas into south-central Missouri. Guidance still supports training west-to-east overnight and 1-inch-per-hour rates in the better cores. Urban streets, low water crossings, and small streams are the first failures. A smaller slight-risk pocket sits over southeast Colorado early Thursday. Southeast Arizona into far southwest New Mexico stays in the same excessive-rainfall slight-risk language on monsoon-style cells.

    Iowa is not the new Slight Risk today, but it is still a just-hit desk. Flood warnings remain on pieces of the Des Moines system, including the Raccoon River at Des Moines and Walnut Creek. Tuesday’s rain is still in the channel. That is extraction and drying work already on the books, not a new watch.

    Restoration read: Kansas–Missouri is tonight’s flood ticket if cells stall. Iowa is yesterday’s water still moving through town. Do not send the same crew to both stories without checking which county actually has a warning now.

    Hotspot 3 — Central Plains and Southwest scatter

    Widely scattered slow-moving storms over hot, humid air in parts of Texas, Oklahoma, and Kansas can still throw damaging gusts even when they stay below watch criteria. Local Severe Thunderstorm Warnings and Special Weather Statements have already fired in the Texas Panhandle and other High Plains counties this afternoon. Southern Arizona and New Mexico higher terrain can produce heavy rain and strong outflow on the same moisture axis as the WPC slight risk.

    Southwest Florida holds a marginal heavy-rain pocket in tropical moisture. That is a local urban-flood and lightning desk, not the national headline.

    Just hit

    Tuesday’s Iowa–Nebraska Slight Risk and the Kauai flood-and-outage work after Hurricane Lowell are yesterday’s tickets. Lowell continues to move away from the islands; there is no new U.S. mainland tropical landfall in the current National Hurricane Center outlook. Today’s new work, if it verifies, is the Ohio–Erie–western New York wind corridor plus localized flash flooding in the Kansas–Missouri slight-risk area.

    Atlantic / Gulf vs. U.S. mainlandNo landfalling hurricaneQuiet on the mainland coastQuiet

    What this means for restoration teams

    Wind at 58–65 mph is roof, siding, gutter, and tree-on-structure work. A brief tornado, if one occurs, is a narrow swath — staff it as a local damage survey, not a regional event. Heavy rain on the Kansas–Missouri slight risk is wet drywall and a 24–48 hour mold clock. Iowa water is already inside some buildings from Tuesday.

    For teams in or near Watch 665: stage before 5 p.m. local, not after the first warning. Property owners should photograph damage in daylight if it is safe, call the carrier, and start extraction the same night if water is inside.

    What this is not

    This is not a regional derecho and not a U.S. mainland hurricane landfall. The work tonight, if it comes, will be scattered: a wind swath through an Ohio or Pennsylvania county, a flooded intersection where Kansas or Missouri cells train, leftover river water in Des Moines. That is the local-storm pattern this desk should staff.

    Looking ahead

    Thursday the front slides toward the Mid-Atlantic, central Appalachians, and Ohio Valley with more wet weather and a continued flood watch in some of the same counties that take storms tonight. Later in the week, SPC language still flags another slight-risk window over parts of the Upper Mississippi Valley. Watch the next Storm Tracker update rather than assuming Watch 665 is the last line of the week.

  • Storm Updates: Iowa–Nebraska Slight Risk, Kauai Flood Aftermath, Heat-Plus-Wind Cells — Tuesday, September 8, 2026

    This is a live Tuesday snapshot of local storm-type events across the United States as of the afternoon of Tuesday, September 8, 2026. The mainland pulse is convective: a Storm Prediction Center Slight Risk of severe thunderstorms from southeast Nebraska across parts of Iowa, mainly damaging wind, plus scattered high-based wind cells on the High Plains. The tropical story is not a U.S. Gulf or Atlantic landfall. It is residual water and outage work on Kauai after Hurricane Lowell passed west of the islands.

    These are the events that generate the restoration work crews actually see: wind-driven roof and siding failures, isolated hail, downed trees on service lines, interior flooding from stalling cells, and — in Hawaii — wind plus flash-flood cleanup after a close hurricane pass. Conditions change fast. Verify with the National Weather Service for the specific county or ZIP before you roll.

    What is live this afternoon

    The SPC Day 1 convective outlook holds a Slight Risk of severe thunderstorms this afternoon and evening from southeast Nebraska across parts of Iowa, including the Omaha–Council Bluffs–Des Moines corridor toward Ames and Waterloo. The headline threat is severe wind gusts. Isolated large hail and a low-end tornado chance remain in the language. A broader Marginal Risk covers parts of the upper Midwest and central Plains. High-based storms over eastern Colorado into western and central Kansas can also produce gusty, occasionally damaging wind.

    Heat is part of the same setup. Heat Advisories cover portions of southeastern Nebraska and southwestern Iowa, with heat-index values near or above 100–108°F. That matters for crew stamina and for how fast wet interiors go to mold if extraction waits overnight.

    No widespread convective watches were in effect at this writing. Expect local Severe Thunderstorm Warnings and Special Weather Statements if cells organize along the front after mid-afternoon.

    Hotspot 1 — Iowa and eastern Nebraska

    A baroclinic zone from southern Nebraska into central Iowa is the focus. Differential heating sharpens it through the day. Storms are expected to initiate along or just north of that boundary late afternoon into evening, with enough shear for supercell and then bowing structures. Damaging wind is the primary restoration exposure. Weak mid-level lapse rates should limit the hail problem compared with a classic Plains supercell day, but quarter-size hail is still in local Hazardous Weather Outlooks.

    NWS offices in the corridor are also flagging locally heavy rain and flash-flood potential tonight where storms train. That is interior water on the same streets that take the wind.

    Cities and counties to watch: Omaha, Council Bluffs, Lincoln fringe, Des Moines, Ames, Waterloo, and counties along and south of I-80 in eastern Nebraska and western/central Iowa.

    Restoration read: wind first — roofs, siding, trees, service drops — then water in the same ZIP if the line slows. Stage dehumidifiers and tarps before the front, not after the first LSR.

    Hotspot 2 — Hawaii: Hurricane Lowell aftermath on Kauai and Niihau

    Hurricane Lowell passed just west of Kauai and Niihau overnight into this morning. Coastal hurricane and tropical-storm warnings have been discontinued as the core moved north. Latest public advisories had the center well north-northwest of Lihue and weakening, with residual flash-flood risk still on the islands from additional heavy rain.

    Impacts already on the ground: widespread power outages at the peak (on the order of 90 percent of Kauai customers in some tallies), damaging wind gusts near 80 mph on Kauai, high surf and coastal flooding, and mountain rainfall measured in the teens of inches in favored terrain. Hawaii issued a tornado watch for Kauai — the first of its kind for the state — during the closest approach.

    Restoration read: this is wind-plus-water cleanup, not a new landfall tonight. Priorities are tarps, wet interiors, electrical safety on outage blocks, and roads still closed by flood or debris. Confirm current county emergency status before treating yesterday’s warning as today’s ticket.

    Hotspot 3 — High Plains wind cells and scattered South-Central storms

    Hot, deeply mixed boundary-layer air over eastern Colorado into western and central Kansas favors high-based storms with gusty to damaging wind this afternoon and evening. Coverage should stay scattered. That is still enough for isolated roof and tree jobs.

    Farther south, Special Weather Statements and strong cells have been firing in parts of east Texas, Louisiana, and Mississippi with 40 mph-class gusts and lightning — below severe criteria in most cases, but enough for local tree-limb and urban-flood work where a cell sits.

    Just hit — Monday into early Tuesday reports

    Preliminary SPC and NWS storm reports from September 7 into early September 8 included brief tornadoes near Hammond, Louisiana; south of Strawberry Lake in McLean County, North Dakota; and east-northeast of Spencer, Nebraska. Hail and wind reports ran through the northern and central Plains. Those are yesterday’s tickets. Today’s new work, if it comes, is the Iowa–Nebraska corridor plus residual Kauai flood and outage jobs.

    East TX / LA / MS cellsGusty wind, lightning, local heavy rainLocal SPS / strong stormsScattered
    Atlantic / Gulf vs. U.S. mainlandNo landfalling hurricaneQuiet on the mainland coastQuiet

    What this means for restoration teams

    Wind at 58–70 mph is roof, siding, gutter, and tree-on-structure work. Isolated hail is vehicle lots, skylights, and soft metal. Heavy rain on the same front is wet drywall and a 24–48 hour mold clock. Kauai is already in the outage-and-water phase.

    For teams in or near the Slight Risk: stage equipment before 5 p.m. local, not after the first warning. Property owners should photograph damage in daylight if it is safe, call the carrier, and get extraction started the same night if water is inside.

    What this is not

    This is not a regional derecho and not a U.S. mainland hurricane landfall. Lowell is moving away from Hawaii. The work tonight, if it comes on the Plains, will be scattered: a wind swath through an Iowa or Nebraska county, a flooded intersection where cells train, a hail report or two. That is the local-storm pattern this desk should staff.

    Looking ahead

    Wednesday’s Day 2 outlook shifts the better-organized severe threat east toward eastern Ohio into western New York. Later in the week, another system may support severe chances again on the central Plains. Watch the next Storm Tracker update rather than assuming today’s Slight Risk stays parked on I-80.

    Sources and how to verify
