What Changed
- SPC Day 1 Convective Outlook (1300 UTC / 7:52 AM CDT Thursday, October 15, 2026, valid 151300Z–161200Z, next by 1630Z) continues only a Marginal Risk of severe thunderstorms across portions of the mid Mississippi and Ohio Valleys for isolated damaging gusts and perhaps a brief tornado. No Slight or higher risk area. No convective watches are currently valid (Watch 685 expired overnight).
- WPC Day 1 Excessive Rainfall Outlook (updated 0644 UTC / 2:44 AM EDT Thursday, October 15, 2026, valid 12Z Thu–12Z Fri) maintains a Moderate Risk of excessive rainfall across portions of West Texas, focused from the Big Bend / Lower Trans-Pecos along and south of I-10 east of the Davis Mountains into the Lower Pecos River basin (Sanderson to north of Del Rio) and northward into the Concho Valley. Areal averages 3–5″ with local higher amounts possible; Slight Risk covers broader southwest TX into southern OK.
- NWS has active Flash Flood Warnings this morning for portions of northern Texas (central Foard, southeastern Hardeman, northwestern Wilbarger, and southeastern Wichita Counties, including Vernon, Crowell, Wichita Falls areas) due to radar-indicated heavy rain of 1–4 inches with additional amounts possible. Flood Watches remain in effect through Friday morning for much of west-central and western Texas (including San Angelo, Abilene, Permian Basin, Big Bend) and residual areas in Oklahoma. No tropical storm or hurricane watches or warnings on the U.S. coast or Gulf; Atlantic quiet; Eastern Pacific Hurricane Simon (weakening) and Tropical Storm Trudy remain offshore Mexico with no U.S. impact.
- Compared with the October 14 afternoon desk (Moderate flood over central Oklahoma / Red River, Slight severe under Watch 685), the Moderate ERO has shifted southwest into West Texas as the front progresses, the Slight severe risk has closed, and the primary overnight driver is now the West Texas flood axis under record-to-near-record PWATs and moisture from Simon remnants. No category change on the Moderate flood lane itself.
Live Status
As of the Thursday morning desk update, October 15, 2026 (approximately 8:18 AM PDT / 10:18 AM CDT / 1518Z), the dominant peril is the Moderate Risk excessive rainfall and flash flooding over West Texas. SPC Day 1 remains Marginal only over the Ohio Valley with no watches or mesoscale discussions elevating the severe threat. Active Flash Flood Warnings cover northern Texas counties under ongoing thunderstorms, while Flood Watches extend across the Moderate and Slight ERO corridors in Texas and residual Oklahoma. High Wind Warnings continue across parts of the Southwest (Arizona, New Mexico, California mountains) and Red Flag Warnings over California Sierra and central/northern areas; these are non-convective products.
Pulse Table
| Lane | Status | Notes (as of ~8:18 AM PDT / 10:18 AM CDT / 1518Z 15 Oct 2026) |
|---|---|---|
| Tropical | None | No named systems threatening U.S. land or Gulf. Atlantic quiet. Pacific: Hurricane Simon (weakening) and TS Trudy offshore Mexico, no U.S. impact. Offshore hurricane warning for Mexico waters only. |
| Severe | Marginal | SPC Day 1 Marginal Risk mid MS / Ohio Valley (isolated wind / brief tornado possible this afternoon/evening). No watches valid. Overnight LSRs primarily wind damage northwest TX / southwest OK and trees OH/WV. Slight Risk closed with overnight convection. |
| Flood | Moderate | WPC Day 1 Moderate Risk West Texas (Big Bend / Stockton Plateau / Lower Pecos / Concho Valley). Slight broader TX into southern OK. Active FFWs northern TX (Foard/Hardeman/Wilbarger/Wichita). Flood Watches through Friday morning west-central/western TX and residual OK. |
| Other | Wind / Fire | High Wind Warnings AZ/NM/TX mountains and CA (gusts 50–70 mph). Red Flag Warnings Sierra and central/northern CA. Non-severe wind and fire weather products. |
Restoration Read
Primary restoration ticket is water and flash flooding over West Texas under the Moderate ERO, with potential for considerable flash flooding where training convection occurs on already moist or complex terrain (low-water crossings, arroyos, urban poor drainage). Residual saturated ground and Flood Watches continue across central/southwestern Oklahoma from the previous Moderate axis. Overnight wind damage claims possible from gusts 60–75 mph in northwest Texas and southwest Oklahoma (power lines, sheet metal, trees). Ohio Valley Marginal supports only isolated tree or minor wind claims if storms organize this afternoon. No tropical surge or coastal claims. Standard posture: verify county-level Flood Warnings and Watches before deploying crews; Turn around, don’t drown on flooded roads. Southwest High Wind and Red Flag products are separate non-convective events.

Looking Ahead One Day
SPC Day 2 outlook indicates a Slight Risk of severe thunderstorms over a portion of the Mid-Atlantic for Friday afternoon and evening (damaging wind gusts and perhaps a brief tornado). WPC Day 2 continues a Moderate Risk of excessive rainfall across portions of West Texas as the front’s slower progression sustains the moisture axis. No tropical development indicated for the U.S. coast or Gulf.
