- SPC Day 1 Convective Outlook (1300 UTC / 7:52 AM CDT Thursday, October 15, 2026, valid 151300Z–161200Z, next update 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. No convective watches currently valid. Unchanged from the prior morning pulse table.
- WPC Day 1 Excessive Rainfall Outlook (updated 1601 UTC / 12:01 PM EDT Thursday, October 15, 2026, valid 16Z Thu–12Z Fri) maintains a Moderate Risk of excessive rainfall across portions of West Texas (Big Bend / Lower Trans-Pecos / Stockton Plateau into Concho Valley). Minor trim of the western extent north/west of the Davis Mountains; high neighborhood probabilities (>70%) for amounts exceeding 5 inches remain centered in the Moderate area. Slight Risk covers broader southwest TX into southern OK. Category and primary focus unchanged from earlier morning desk.
- NWS has active Flash Flood Warnings as of ~11:50 AM CDT for southeastern Martin and northeastern Midland Counties (1.5–2.5 inches fallen, rates 1–2 in/hr, considerable threat) and extended/continued for central Foard, southeastern Hardeman, northwestern Wilbarger Counties (1–3 inches, additional up to 1 inch). Flood Watches continue through Friday morning for west-central Texas (San Angelo, Abilene, Tom Green, Taylor and surrounding) and residual Oklahoma areas. Near-term high-end Slight noted in northwest Texas per WPC MPD #1498.
- No tropical storm or hurricane watches or warnings on the U.S. coast or Gulf. Atlantic quiet. Eastern Pacific Hurricane Trudy (intensifying, Hurricane Warning for Mexican offshore waters) and Tropical Storm Simon remain offshore with no U.S. land threat. Tropical lane unchanged.
- Nothing material moved on the national severe board since the earlier morning pulse. The organized Slight Risk closed overnight; the Moderate flood axis remains stabilized on West Texas under anomalous moisture (+2 to +3 SD PWATs) and frontal forcing.
Live Status
As of the Thursday morning desk, October 15, 2026 (approximately 10:13 AM PDT / 12:13 PM CDT / 1713Z), the dominant open threat is the WPC Moderate Risk of excessive rainfall over West Texas. Anomalous October moisture and a southward-progressing cold front continue to support heavy convective rainfall, with the strongest signal for 3–5+ inch totals (local higher) along and south of I-10 east of the Davis Mountains into the Lower Pecos and Concho Valley. Active Flash Flood Warnings are live in the Midland/Martin and northern Texas (Foard/Hardeman/Wilbarger) areas with radar-indicated and observed flooding. SPC Day 1 remains Marginal only over the Ohio Valley with no watches. High Wind Warnings and Red Flag Warnings persist across the Southwest and California but are non-convective.

| Flood | Moderate | WPC Day 1 Moderate Risk West Texas (Big Bend / Stockton / Lower Pecos / Concho). Slight broader TX into southern OK. Active FFWs northwestern Midland/Martin and Foard/Hardeman/Wilbarger. Flood Watches through Friday morning west-central TX and residual OK. Near-term high-end Slight northwest TX. |
| 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 products. |
Restoration Read
Primary restoration ticket is water and flash flooding over West Texas under the Moderate ERO, with potential for considerable flash flooding on complex terrain, low-water crossings, arroyos, and urban poor drainage where training occurs. Residual saturated ground and Flood Watches continue across Oklahoma from the prior Moderate axis. Overnight wind damage claims remain possible from 60–75 mph gusts in northwest Texas and southwest Oklahoma. Ohio Valley Marginal supports only isolated tree or minor wind claims if storms organize later today. No tropical surge or coastal claims. Standard posture: verify county-level Flood Warnings and Watches before deploying; Turn around, don’t drown on flooded roads. Southwest High Wind and Red Flag products are separate non-convective events.
