Storm Updates: Kansas Flash Flood Emergency, Texas Water — Thursday, October 1, 2026

This is a live Thursday afternoon snapshot for October 1, 2026. The organized severe window is small. The Storm Prediction Center 2000 UTC Day 1 convective outlook, updated 2:49 p.m. CDT, holds a Marginal Risk only across parts of southern Kansas and northwest Oklahoma — about 16,457 square miles and roughly 121,676 people, with Liberal, Kansas, and Woodward, Oklahoma, named in the risk table. No severe thunderstorm watch number is attached to that outlook. The live ticket is water. The National Weather Service in Dodge City issued a Flash Flood Emergency at 2:32 p.m. CDT for Dodge City and central Ford County, tagged catastrophic damage threat, after 3 to 6 inches of rain with another 3 to 5 inches possible. Restoration exposure this afternoon is interior water, saturated streets, and a short gusty-wind tail on the High Plains — not a hail swath and not a tornado outbreak.

These are county-scale thunderstorms and training rain, not a U.S. landfalling hurricane. Hurricane Rachel is in the eastern Pacific, south of Baja California Sur, with no coastal watches or warnings in effect on the 2 a.m. MST advisory and a track taking the center away from mainland Mexico. The Atlantic basin has no tropical cyclones this afternoon. Conditions change fast. Verify the county warning at weather.gov before a crew rolls.

What is live this afternoon

SPC’s Day 1 update valid from 2000 UTC Thursday through 1200 UTC Friday puts a 5 percent wind probability and a 2 percent tornado probability on that southern Kansas and northwest Oklahoma Marginal. No hail risk area is drawn. Mesoscale Discussion 2345, issued 1:32 p.m. CDT, covers southwestern Kansas into far northwestern Oklahoma and rates watch issuance at 5 percent. The discussion notes several storms undercut by the front produced 40 to 50 knot gusts from Hamilton to Finney counties, and that a brief tornado is most plausible in the warm sector along the Kansas–Oklahoma border — too localized, in SPC’s words, to warrant a watch. Filtered storm reports from 1200 UTC today show no tornado reports and no hail reports. Two wind reports landed near Garden City: 58 mph and 59 mph, 3 miles northwest of Pierceville in Finney County, from the Garden City ASOS at 12:54 p.m. and 1:02 p.m. CDT.

The Weather Prediction Center Day 1 excessive-rainfall point file issued 3:26 p.m. EDT, valid 1927 UTC Thursday through 12 UTC Friday, keeps a Moderate Risk of rainfall exceeding flash-flood guidance on a swath the point string ties through southwest and north Texas — Uvalde, Fort Worth Spinks, McKinney, Paris — and east toward the southern Appalachians near Morristown, Tennessee. A Slight Risk covers a broader corridor from the central Plains, including Hill City and Manhattan, Kansas, Falls City, Nebraska, and Lamoni and Iowa City, Iowa, into the Midwest fringe. A separate Marginal pocket sits over South Florida. The overnight Moderate discussion that was valid only through 12 UTC Thursday has expired; the afternoon product is the one above, and the warnings below are what is actually in effect.

Hotspot 1 — Dodge City and southwest to central Kansas

This is the live emergency. NWS Dodge City’s 2:32 p.m. CDT Flash Flood Warning for central Ford County runs until 5:30 p.m. CDT and includes the Flash Flood Emergency language for Dodge City, Ford, Fort Dodge, and Wright. Source is emergency management. Damage threat is catastrophic. A separate Dodge City warning covers southwestern Gray, southern Haskell, northwestern Meade, and northeastern Seward counties until 6:00 p.m. CDT, including Sublette and Copeland, after 1 to 3 inches with another half inch to an inch possible. Farther east, NWS Wichita has a Flash Flood Warning until 8:00 p.m. CDT for northeastern McPherson and northwestern Marion counties, including Canton, Lehigh, and Roxbury, with up to 3 inches already down and another 3 inches possible; damage threat considerable. NWS Topeka has a warning until 7:00 p.m. CDT for Geary and northwestern Morris counties after 3 to 5 inches, including Junction City and Grandview Plaza and Interstate 70 between mile markers 291 and 302 and 310 and 315. An earlier Topeka statement kept flooding in play for Manhattan, Wamego, and the Milford and Tuttle Creek lake areas.

Restoration read: this is a water ticket already open, not a forecast. Extraction, contents, and a mold clock start where water entered finished space. Do not route a crew across a closed low-water crossing to reach the loss. Wind is secondary here — the Garden City gusts are a roof-and-tree check, not the headline.

Hotspot 2 — San Antonio metro and northeast Texas

NWS Austin/San Antonio kept a Flash Flood Warning in effect until 7:00 p.m. CDT for northern Atascosa, Bexar, and western Wilson counties. At 3:23 p.m. CDT, emergency management reported flash flooding with numerous low-water crossings closed. Leon and Olmos creeks had responded. One to 4 inches had fallen, with up to another inch possible. Damage threat is considerable. Locations in the warning text include San Antonio, Schertz, Converse, Universal City, Live Oak, Pleasanton, Floresville, Helotes, and Randolph AFB. NWS Shreveport issued a Flash Flood Warning at 3:23 p.m. CDT until 6:30 p.m. CDT for northwestern Cherokee and central Smith counties, including Tyler, Jacksonville, Whitehouse, and Lindale, with 1 to 2 inches down and rates of 1 to 2 inches per hour expected.

SPC’s 2000 UTC update also notes convective coverage increasing over south-central and south Texas in hot, humid air. A localized strong gust is possible with the strongest downdrafts. Poor mid-level lapse rates and weakening shear keep that below a broader severe risk. Restoration read: San Antonio is observed water and closed crossings. Tyler is a radar-indicated flood warning with a short fuse. Treat both as urban-drainage and creek jobs, not as a severe-wind corridor.

Hotspot 3 — Southern Kansas and northwest Oklahoma Marginal

The only categorical severe area on the afternoon Day 1 outlook is the trimmed Marginal from southern Kansas into northwest Oklahoma, centered on Liberal and Woodward. The 11:28 a.m. CDT discussion, still carried as the previous discussion on the 2000 UTC product, describes a weak surface low over northwest Oklahoma and the northeast Texas Panhandle, a front northeast across Kansas, and a Pacific cold front south across the southern Plains. Cool temperatures aloft, around minus 10 to minus 11 C at 500 mb, can support small hail, strong to locally severe winds, and perhaps a brief tornado until the cold front undercuts the storms by late afternoon or early evening. SPC trimmed the northwestern edge of the Marginal where severe probabilities dropped behind ongoing convection.

A low-probability isolated storm is also noted along the surface front in northeastern Missouri and western Illinois later this afternoon or evening. Poor lapse rates and limited buoyancy keep severity muted if anything develops. Restoration read: stage a small wind-and-tree check for Liberal, Woodward, and the Kansas–Oklahoma border counties. Do not staff it like a watch.

Just hit

The overnight story is already a ticket, not a new outlook. The 0100 UTC Day 1 outlook from Wednesday evening had carried a Slight Risk from Texas into southwest Oklahoma and over north-central Kansas, with a tornado window noted for the next hour or two mainly in north-central and northeast Kansas. Today’s 12Z-onward SPC filtered page does not list a tornado or hail report. What verified into this afternoon is rain: Dodge City’s 3 to 6 inches, Junction City’s 3 to 5 inches, and San Antonio’s closed crossings. The morning Storm Tracker desk is the prior URL for that overnight close-out.

Pulse table

What this means for restoration teams

Ford County is the priority desk. A catastrophic Flash Flood Emergency means finished-floor water, contents, and electrical in low structures are already in play where the water reached them. Photograph only from safe ground. The San Antonio warning is the second water desk: crossings are closed, so access is the constraint, not the estimate. Tyler is a shorter fuse on the same rain axis. The Marginal in Liberal and Woodward is a gust check — the only filtered wind reports so far are the 58 and 59 mph Garden City readings. A 60 mph peak is the most probable gust in MD 2345’s language, which is roof edge, fascia, and tree-on-structure work if it verifies, not a regional tarp campaign.

Do not send the same crew from Dodge City to San Antonio. They are separate warning offices and separate hydrology. Kansas water is High Plains urban and small-stream flooding under a slow upper low. San Antonio water is creek response in Bexar County with emergency-management confirmation.

What this is not

This is not a derecho, not a tornado outbreak, and not a U.S. hurricane landfall. SPC drew no hail risk area on the 2000 UTC outlook. No severe thunderstorm watch is in effect on that product. Rachel is a Pacific hurricane south of Baja with no U.S. coastal warning. Tropical Storm Nolo is in the central Pacific and is not a mainland landfall. The work this afternoon, where it is already reported, is floodwater in Ford County, Geary County, the San Antonio metro, and Smith County.

Looking ahead

SPC’s Day 2 convective outlook, issued 11:54 a.m. CDT and valid Friday into Friday night, forecasts no severe thunderstorm areas. A cold front is expected to reach the southern Mid-Atlantic, the Tennessee Valley, and the Texas coast by 12 UTC Saturday, with a broken band of showers and storms along it and limited destabilization where morning rain lingers. The flood story can outlast the severe story. Friday’s desk is leftover high water in Kansas and Texas, not a new Slight Risk.
