This is a live Friday afternoon snapshot of local storm-type events across the United States as of Friday, September 11, 2026. The organized pulse is still ahead of most radar cores: the Storm Prediction Center 2000 UTC Day 1 Convective Outlook keeps a Slight Risk of severe thunderstorms across the Upper Midwest for late this afternoon and tonight. No convective watches are currently valid. Mesoscale Discussion 2281, issued 1937 UTC, flags a lower-end damaging-wind threat over parts of southern Virginia and northern North Carolina with watch issuance unlikely. The Weather Prediction Center holds a Slight Risk of excessive rainfall in far southern Arizona and northern Minnesota.
These remain county- and ZIP-scale thunderstorms, not a mainland hurricane landfall. Tropical Storm Norbert is in the Eastern Pacific well west-southwest of Baja California and poses no threat to U.S. land. Restoration exposure this afternoon is wind, water, hail, and trees: large hail and damaging wind in the Minnesota–northeast South Dakota Slight Risk, isolated wind in the Virginia–North Carolina scatter, flash-flood rates in northern Minnesota and Santa Cruz County, Arizona, plus residual hail and pole work from last night’s Texas Panhandle event. Conditions change fast. Verify with the National Weather Service for the specific county or ZIP before you roll.
What is live this afternoon
No severe thunderstorm or tornado watches are in effect as of the SPC watch page update Friday afternoon. The most recently issued watch remains Watch 665 from earlier in the week. Today’s official Local Storm Reports page (1200 UTC Friday through 1159 UTC Saturday) still shows no new tornado, hail, or wind reports in that window. Last night’s reports sit on the September 10 LSR page.
SPC’s 2000 UTC Day 1 outlook (forecaster Wendt, issued 0300 PM CDT) is mostly on track from the morning package. Scattered severe thunderstorms capable of large hail (some 2+ inches), damaging winds, and a couple of tornadoes are expected late this afternoon and tonight across parts of the Upper Midwest. Initiation farther south into the central Plains remains more uncertain and conditional. Marginal wind/hail probabilities were extended into more of central Kansas for overnight conditional storms as the cold front reaches northern Kansas Saturday morning.
WPC’s Day 1 Excessive Rainfall Outlook (updated 1601 UTC, valid 16Z Friday–12Z Saturday) keeps Slight Risk language over far southern Arizona and northern Minnesota. The 16Z update expanded a Marginal Risk eastward across more of the Florida Panhandle for 1–2+ inch local rates. Mid-South, Tennessee Valley, central Gulf Coast, and Southern Appalachians stay in the more widespread thunderstorm/flash-flood conversation at Marginal intensity.
Hotspot 1 — Upper Midwest Slight Risk (northeast SD into western and northern MN)
This is still the primary organized severe corridor. A mid-level shortwave and cold front support a narrow corridor of 60s F dewpoints, moderate destabilization, and 35–45 kt of deep-layer shear. Initial supercells favor large hail, isolated 2+ inches possible. Mode should trend toward clusters and bowing segments this evening as the low-level jet strengthens, shifting the main hazard toward damaging wind. A couple of tornadoes remain in the official language if any cells stay semi-discrete into early evening. The wind threat is expected to wane with eastward extent into western Wisconsin late tonight as the instability corridor stays narrow.
Cities and counties to watch: Watertown and Aberdeen vicinity in South Dakota; Willmar, St. Cloud, Fergus Falls, Brainerd, Hibbing, Duluth, and the Minnesota Arrowhead. Restoration read: hail first, then wind and trees after dark. Stage roof tarps, generators, and tree crews on the Minnesota side of the Slight Risk before evening clustering. Photograph only in remaining daylight if it is safe.
Hotspot 2 — Southern Virginia and northern North Carolina (MD 2281)
Mesoscale Discussion 2281 (valid 1937–2200 UTC) covers parts of southern Virginia and northern North Carolina. A stationary boundary from far northeastern North Carolina into south-central Virginia is the focus. Moderate surface-based buoyancy and steepening low-level lapse rates support loosely organized clusters capable of locally damaging gusts of 55–70 mph and isolated/marginally severe hail up to about 1.25 inches. Watch probability is 20 percent — watch unlikely.
Offices in the attention line: AKQ, MHX, LWX, RAH, RNK. Restoration read: treat this as scattered wind and tree work, not a regional line. One strong cluster can still drop a tree on a service drop or peel a section of roof. Do not staff it like Watch 665 from Wednesday.
Hotspot 3 — WPC flood pockets: northern Minnesota and far southern Arizona
The same shortwave that supports the Upper Midwest Slight Risk also carries a WPC Slight Risk of excessive rainfall over northern Minnesota. Official discussion cites precipitable water in the upper climatological percentile, possible training near the warm front, 1–2 inches (locally up to 3 inches), and rates approaching 1.5 inches per hour Friday afternoon and evening.
Far southern Arizona, especially the Santa Cruz County corridor, remains the other Slight Risk flood pocket on monsoon moisture with precipitable water above 1.5 inches. HREF guidance earlier today showed moderate-to-high chances of 3-hour QPF exceeding flash-flood guidance there. The Florida Panhandle was added to the broader Marginal flood language on the 16Z update for coastal 1–2+ inch rates.
Restoration read: northern Minnesota can be a dual ticket — hail/wind plus interior water if cores train. Southern Arizona is a flash-flood and poor-drainage desk. Florida Panhandle is localized urban flooding, not the national headline.
Just hit
Thursday evening into early Friday remains the live claim pile. Official September 10 LSRs include 2.25-inch hail near Lake Tanglewood and 2.00-inch hail at Timbercreek Canyon in Randall County, Texas; 1.75-inch and 1.25-inch stones around Lake Tanglewood and Pantex; an 87 mph thunderstorm gust 1 SE of Colby, Thomas County, Kansas; 67 mph near Pantex; 65 mph at Plainview, Hale County, Texas, with snapped power poles, an overturned construction trailer, damaged vehicles, and fences down; plus additional 60–62 mph gusts on the Texas South Plains. Residual high-water work from overnight Flash Flood Warnings in north-central West Virginia and southeastern Ohio is still on yesterday morning’s books.
No Atlantic tropical cyclone is present. NHC’s 200 PM EDT Friday Tropical Weather Outlook states tropical cyclone formation is not expected in the Atlantic, Caribbean, or Gulf of America during the next 7 days. Tropical Storm Norbert, 65 mph as of the late-morning Eastern Pacific package, is moving west well offshore and is not a U.S. land threat.

What this means for restoration teams
The Texas Panhandle and Colby, Kansas, hits are already tickets: hail roofs and vehicles in Randall and Carson counties, wind-driven pole and debris work around Plainview and Colby. Today’s new work, if it verifies, is the Upper Midwest Slight Risk after peak heating — hail swaths first, then tree-and-wire clusters. Northern Minnesota can add interior water on the same shift. Virginia–North Carolina is a local wind desk, not a watch-scale deployment.
Stage Minnesota tarps and tree crews before dark. Property owners should photograph damage in daylight if it is safe, call the carrier, and start extraction the same night if water is inside. Do not send the same crew to both the Minnesota Slight Risk and last night’s Texas recovery without checking which county actually has a warning now.
What this is not
This is not a regional derecho and not a U.S. mainland hurricane landfall. There is no live tornado or severe thunderstorm watch as of this afternoon package. The work tonight, if it comes, will be scattered: a hail swath through a Minnesota or South Dakota county, a wind-downed tree in southern Virginia, a flooded wash in Santa Cruz County, Arizona, or leftover pole work in Hale County, Texas. That is the local-storm pattern this desk should staff.
Looking ahead
Saturday’s Day 2 Convective Outlook (1730 UTC, forecaster Jewell) drops to Marginal over parts of the Central Plains and from Ohio and West Virginia into western Pennsylvania. Widely scattered strong-to-severe storms are possible Saturday afternoon and evening over parts of the Central Plains, with isolated activity also possible in the Upper Ohio Valley. Critical fire-weather conditions remain in today’s fire outlook. Watch the next Storm Tracker update rather than assuming the Upper Midwest Slight Risk is the last line of the week.
