Inspired by Tygart Media Storm Tracker — Storm Updates: Kansas–Oklahoma Watch 667, Ohio Valley Flood Pulse — Saturday, September 12, 2026 — https://tygartmedia.com/storm-updates-september-12-2026-kansas-oklahoma-watch-667-ohio-valley-flood/.
What changed since the morning companion: Watch 666 is no longer the story. Severe Thunderstorm Watch 667 is in effect from 3:45 p.m. until 10:00 p.m. CDT for southwest Kansas, Oklahoma, and the Texas Panhandle. The 2000 UTC Day 1 outlook expanded the Slight Risk southwest across parts of western Oklahoma after isolated initiation along remnant outflow. Mesoscale Discussions 2286 and 2287 framed the watch — peak gust language 65–80 mph, peak hail 1.50–2.50 inches, tornado probability low. Official Saturday LSR (12 UTC Saturday onward) was still empty as of mid-afternoon; treat homepage ticks as unofficial until they land on the LSR page. WPC still holds a Slight Risk of excessive rainfall over the Ohio Valley and Mid-Atlantic and stretched that language north through eastern Pennsylvania, northern New Jersey, the New York City metro, and lower Long Island for late Saturday night into Sunday. North Georgia morning Flash Flood Warnings (Cobb, DeKalb, Douglas, Fulton, Carroll, Paulding) are mostly expired; the water is still in streets and buildings. That is already a ticket, not a new watch.
Owner / Principal
Capital splits three ways tonight, not one. First: Watch 667 wind and isolated 2-inch hail — stage tarps, glass, roof, and generator inventory on the Dodge City–Wichita–Norman–Amarillo axis before dark. Second: Ohio Valley and I-95 water if cells train — extraction and drying, not a roof surge. Third: metro Atlanta leftover from this morning — already inside some structures, already on a mold clock. Do not treat Watch 667 as a regional CAT or a derecho. Isolated 80 mph gusts on a 102–104°F mixed layer are tree-and-roof tickets in a narrow corridor. Hold overtime on quiet coasts. Photograph-in-daylight still matters: owners who wait until after 10 p.m. CDT will hand you weaker first photos. Do not invent a tornado watch SPC has not issued.
GM / Ops
Board Watch 667 first. Call lists: Wichita, Hutchinson, Emporia; Enid, Ponca City, Oklahoma City metro fringe; Alva to Chandler; Amarillo and the eastern Texas Panhandle. Neighboring NWS offices: Dodge City, Wichita, Norman, Tulsa, Amarillo. Tree, tarp, and generator crews need to be staged before 5 p.m. CDT, not after the first warning. Pittsburgh, northern West Virginia, Richmond, Baltimore, Philadelphia, and the I-95 urban core stay on the water board tonight into Sunday morning — different crew mix, different trucks. Atlanta leftover water stays with the local extraction desk; do not raid that inventory for Oklahoma wind. Confirm the live county warning before you move anyone between a Plains hail job and an Ohio Valley basement. Do not pull a paid commercial dry-in in Georgia for a cell that has not produced an LSR.
Project Manager
If Watch 667 verifies, first four hours: exterior photo set in remaining daylight if it is safe, interior moisture map, then tarp or extract. Do not open walls until the map and photo set are locked. Occupied residential gets contents protection and a category call before demolition. Vacant commercial can take more aggressive dry-in once power is confirmed safe. Dual-peril houses on the Ohio Valley–Mid-Atlantic Slight — wind-driven rain plus training cores — log both perils on the first visit. Atlanta leftover water is already hours old; treat it as an active drying job, not a wait-and-see. On any new 2-inch hail swath, keep vehicle and soft-metal documentation separate from the roof file. Tree-on-service-drop tickets are one address, one cluster — not a line event.
Estimator
Three scopes, three files: hail, wind, water. Watch 667 work, if it verifies, is isolated large hail plus measured gust damage — not a statewide replacement estimate from a driveway shot after dark. Hail size and impact density still beat a phone photo of one shingle. Ohio Valley and Mid-Atlantic tickets need extraction, drying, and a 24–48 hour mold-clock line even when the roof looks intact. Atlanta leftover from this morning is already on that clock; do not write it as a same-hour emergency if the warning expired at midday and the water has been sitting. Leave ALE and contents for the residential conversation after livability is known. Friday’s closed LSR book (Minnesota tornado near Artichoke, Tarrant and Bexar County hail, Carolinas–Virginia tree swath) stays in residual files — do not mix those claim numbers into tonight’s Watch 667 estimate.
Technician
Meter and category before any wall opens. Plains wind jobs can hide hail in gutters and soft metal; photograph before discard. Ohio Valley and Mid-Atlantic interior water is category 2 until the source is proven clean — training rain on already-wet ground is not automatically category 1. Atlanta leftover water has had hours to migrate; map it, do not assume the first wet room is the only room. PPE stays on for high-water work still draining. On outage blocks under Watch 667, confirm electrical safety before air movers; generators stay outside and downwind. Do not start insulation removal until the PM signs the moisture map. Burn-scar flash-flood watch in northeast Oregon and southeast Washington is debris-flow country — local hydrologic, not a CAT roll.
Business Development
Commercial accounts under Watch 667 get a short, local note before dark — facility managers in the watch counties, not a national blast. Quiet outreach beats door-knocking a risk that has not yet produced an official Saturday LSR. Ohio Valley and I-95 commercial property managers with poor-drainage docks and below-grade electrical get the flood language, not hail language. Atlanta leftover water is already a same-day call to standing commercial accounts in the warned counties this morning. Skip mass social for Tropical Storm Norbert; it is over the open eastern Pacific and is not a U.S. land threat. Do not pitch. Do not name clients. Confirm the county warning before you send a note that sounds like a watch is up in a county that is only Marginal.
Commercial vs Residential
The event splits by occupancy and by desk. Watch 667 commercial is membrane, HVAC, glass, and after-hours lift access on a hot, high-based wind day; residential in the same counties is vehicles, soft metal, trees on service drops, and living-space water if hail punches the roof. Ohio Valley–Mid-Atlantic commercial is dock, elevator pit, and underpass flooding if cores train; residential is the basement and the 24–48 hour mold clock. Atlanta leftover commercial is already-wet interiors from this morning’s warnings; residential is the same water in occupied space with a category call before demo. Stage commercial roof and dry-in first on verified hail; stage residential contents and category documentation on verified water. Do not send one crew to Oklahoma wind and Pittsburgh water without checking which county actually has a warning now.
