Inspired by Tygart Media Storm Tracker — Storm Updates: Kansas–Oklahoma Watch 670 + Midwest–Montana Flood Moderate — Saturday, September 19, 2026 — https://tygartmedia.com/storm-updates-september-19-2026-kansas-oklahoma-watch-670-midwest-montana-flood-moderate/.
What changed since the morning companion: a convective watch is now live. Severe Thunderstorm Watch 670 runs from 3:20 p.m. until 11:00 p.m. CDT across central into northeast Kansas, western into north-central Oklahoma, and the eastern Texas Panhandle. Primary language is scattered damaging winds, isolated gusts to 75 mph, and isolated hail to 1.5 inches. SPC Mesoscale Discussion 2309, which had only flagged the corridor for watch consideration, is overtaken by the watch itself. The 2000 UTC Day 1 outlook still holds Slight over about 56,800 square miles and nearly 2 million people, with Wichita, Topeka, Lawrence, Salina, and St. Joseph inside the contour. WPC’s 1602 UTC Day 1 Excessive Rainfall Outlook kept Moderate risk over eastern Iowa, northern Illinois, and northern Indiana, plus a second Moderate pocket over southern Montana. Live LSRs this window include a 67 mph gust near Freedom, Woodward County, Oklahoma; 59–66 mph near Byers, Arapahoe County, Colorado; 1.25-inch hail north of Matheson, Elbert County, Colorado; and already-down trees and wires in Tennessee, Alabama, and Georgia. Those tree reports are tickets, not tomorrow’s map. There is still no U.S. mainland tropical watch.
Owner / principal
Morning’s hold on Kansas is over. Authorize a watch-scale wind and hail envelope through 11 p.m. CDT for the Watch 670 box, then a next-day roof and tree pass if gusts verify. Do not cancel the Midwest water authorization. Eastern Iowa through northern Indiana is still the occupied-structure extract desk into Sunday morning. Southern Montana remains a third envelope — burn-scar mud and small drainages, not a Kansas add-on. Three overtime codes, not one national surge.
Cash now: tarps, generators, glass kits, and a tree-and-service-drop crew on the watch. Keep extractors and dehumidifiers on the Iowa–Illinois line. Do not raid a Quad Cities dry-out to staff Wichita because a watch posted. Southeast tree jobs from this afternoon’s Tennessee Valley cells are local-branch work. Quiet branches stay on standing rebuilds.
GM / ops
Four boards. Board 1 — Watch 670: Wichita, Hutchinson, Salina, Manhattan, Topeka, Lawrence, Alva, northwest Oklahoma, eastern Texas Panhandle, St. Joseph fringe. Stage roof, glass, and tree before dark. Board 2 — Midwest Moderate: eastern Iowa, northern Illinois, northern Indiana. Extraction stays first-out tonight. Board 3 — High Plains LSRs already on the ground: Byers wind, Matheson hail, Freedom gust. Assign from the local Colorado / western Kansas / northwest Oklahoma branch. Board 4 — southern Montana water and leftover Southeast trees (Signal Mountain, South Pittsburg, Etowah, Jackson County Alabama, Warm Springs, Highland Park). Do not send one crew from a Kansas watch county to a Cedar Rapids basement without checking which product is live in that ZIP.
Ohio Valley Marginal was trimmed on the north edge after outflow cooled the airmass. Indianapolis and Columbus stay on-call, not pre-positioned. Atlanta Marginal is leftover wet microbursts, not a new watch.
Project manager
Watch 670 files: exterior wind and hail photos in remaining daylight if it is safe. Separate frames for each elevation, open planes, vehicles, and any interior water that followed wind-driven rain. Tarp open decks before you leave the site. Do not treat a 67 mph report two counties away as proof that this roof failed.
Midwest water files: safety walk, power status, photo of every wet plane before furniture moves, then extract. Occupied homes get contents protection and a written category call before demolition talk. Vacant slabs get the same photos plus a locked-door log. If a cell trains over the same ZIP for more than an hour, treat it as an occupied-structure water job tonight, not a Monday callback. Montana: access and debris first; do not promise an ETA across a live burn-scar drainage. Southeast trees: photograph the path and the opening; call the utility before anyone cuts a drop.
Estimator
Split the files. Watch 670 is wind first, hail second. Wind at 60–75 mph is trees on drops, isolated peel, gutter, and glass — not an automatic full roof. Hail to 1.5 inches is functional shingle and vehicle work; do not write a full roof from one slope photo. High Plains LSRs already give you measured numbers near Byers and Matheson; price those counties from the report, not from the outlook contour.
Midwest Moderate is overland and training rain. Treat unknown source water as Category 3 until you prove otherwise. Price extraction and standing-water haul-off from meters, not a driveway photo. WPC language still allows cores over 5 inches and low-end 8-inch probabilities in the better Midwest cells; that is a supplement path, not a reason to pre-write a rebuild. Montana burn-scar mud is not a standard interior water loss. Southeast tree jobs are unit-price tree, board-up, and interior only where an opening is documented.
Technician
On the watch: treat downed lines as live until the utility marks them. Photograph the tree path and any opening before you cut. Meter and write category before any wall opens if rain followed the wind. Heat that sat near 100 F from Texas into southern Kansas this afternoon is a rest-cycle problem even after sunset; do not skip water because the first call is a tarp.
On Midwest water: PPE for Category 3 and for any site with sewage, agricultural runoff, or standing basement flood. No generator into standing water. If the panel is wet or the street is dark, stop. Montana runoff can carry ash and debris; that is not a clean-water residential call. Do not drive a live arroyo, low-water crossing, or burn-scar wash. The ticket is after the water drops.
Business development
Call damage and standing accounts, not the outlook. Watch 670 commercial managers along I-35 and I-70 get one line: after-hours roof and dock access if a warning or measured gust hits their park. Midwest commercial gets a flood heads-up on slabs and docks only where a warning is live or water is already inside. Montana commercial is ranch, mill, and municipal buildings on named drainages — not a statewide blast. Southeast tree work is follow-up on open files in the named Tennessee, Alabama, and Georgia counties.
What not to send: a national “storm is coming” email, a DMA-wide geo-fence, or a pitch. Name the county and the peril. Do not name clients.
Commercial vs residential
The afternoon split is real. Commercial inside Watch 670 is warehouse and big-box membrane, rooftop units, and after-hours dock access if a line segment peels. Residential on that same box is shingles, vehicles, trees on service drops, and wind-driven rain if a plane opens. Commercial on the Midwest Moderate is slab warehouses and grocery back rooms when the lot ponds; residential is contents, possible ALE if sleeping rooms fail, and a 24–48 hour mold clock on occupied extract. Montana commercial is access-constrained industrial and municipal; residential there is well water and debris, not a standard pack-out. Southeast commercial is parking-lot trees and storefront glass; residential is wires and openings.
Do not write ALE on a vacant warehouse. Do not skip after-hours access planning on a grocery that still has product on the floor. Do not mix a Sedgwick County tarp crew with a Linn County extract crew without checking which product is live.
