Storm Updates: West Texas Moderate Flood — Oct 15

Tropical: None · Severe: Marginal · Flood: Moderate

What Changed

• SPC Day 1 Convective Outlook (1300 UTC / 7:52 AM CDT Thursday, October 15, 2026, valid 151300Z–161200Z) 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. No convective watches currently valid. Unchanged from the morning desk.
• 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 probabilities for >5″ amounts remain centered in the Moderate area. Slight Risk covers broader southwest TX into southern OK. Category and primary focus unchanged.
• NWS maintains active Flash Flood Warnings this afternoon for portions of northern and western Texas, including northwestern Midland County (ongoing heavy rain of 1.5–2.5 inches with 1–2 inches per hour rates) and residual northern Texas counties (Foard, Hardeman, Wilbarger, Wichita). Flood Watches remain in effect through Friday morning for much of west-central and western Texas. Residual Flood Watches continue in parts of Oklahoma. No category change on the flood lane.
• No tropical storm or hurricane watches or warnings on the U.S. coast or Gulf. Atlantic quiet. Eastern Pacific Hurricane Trudy (rapidly intensifying offshore Mexico) and Tropical Storm Simon remain offshore with no U.S. land threat. Tropical lane unchanged from morning.
• Nothing material moved on the national severe board since the morning pulse table. The organized Slight Risk closed overnight; the Moderate flood axis remains stabilized on West Texas under anomalous moisture and frontal forcing.

Live Status

As of the Thursday afternoon desk, October 15, 2026 (approximately 9:20 AM PDT / 11:20 AM CDT / 1620Z), the dominant open threat is the WPC Moderate Risk of excessive rainfall over West Texas. Anomalous October moisture (PWAT anomalies +2 to +3 standard deviations) and a southward-progressing cold front continue to support heavy convective rainfall rates of 1–2+ inches per hour, with areal averages of 3–5 inches and local maxima higher expected along and south of the I-10 corridor east of the Davis Mountains into the Lower Pecos and Concho Valley. Active Flash Flood Warnings cover northwestern Midland County and residual northern Texas areas under ongoing thunderstorms. Residual saturated ground and Flood Watches across parts of Oklahoma keep secondary flood tickets active. SPC Day 1 is only Marginal over the Ohio Valley with isolated damaging wind gusts and a low-end tornado threat possible this afternoon/evening near the warm front if storms organize. No watches are in effect. High Wind Warnings and Red Flag Warnings remain active in parts of the Southwest and California but are non-convective products.

Hotspots

West Texas (Big Bend / Stockton Plateau / Lower Pecos / Concho Valley including San Angelo vicinity): Primary Moderate Risk zone. Focused heavy rainfall expected this afternoon into tonight as the front slows and the nocturnal low-level jet enhances convergence. Flash flooding of creeks, low-water crossings, arroyos, and urban poor-drainage areas is the main concern. HREF/REFS neighborhood probabilities remain high (above 70 percent) for amounts exceeding 5 inches centered within the Moderate area. Areal averages 3–5″ with locally higher possible.

Northern and western Texas (Midland, Permian Basin, residual northern counties): Active Flash Flood Warnings this morning into early afternoon, including northwestern Midland County where radar indicates 1.5–2.5 inches already fallen with continued heavy rates. Flood Watches extend through Friday morning across the Permian Basin, Big Bend, and west-central Texas. Saturated soils and ongoing convection elevate the flash flood risk for any additional training cells.

Ohio Valley / Mid Mississippi Valley: Marginal Risk only. Isolated severe thunderstorms possible this afternoon and evening near the warm front with damaging wind gusts and a brief tornado or two possible. Limited buoyancy from widespread clouds and modest heating should keep the threat isolated. Secondary to the flood threat farther southwest. No watches or mesoscale discussions elevating the severe side.

Just-Hit

Overnight and early-morning convection across the southern Plains produced damaging wind reports (gusts 60–75 mph, power lines down, sheet metal and tree damage) in northwest Texas and southwest Oklahoma, plus scattered tree damage in Ohio and West Virginia. Flash flooding occurred or was radar-indicated in multiple northern Texas and southwestern Oklahoma counties this morning, with 1–4+ inches fallen in warned areas including Midland, Wichita Falls, Vernon, and Crowell vicinities. Residual river rises possible on smaller basins. Preliminary tornado report earlier near Fort Stockton TX remains under survey; no new confirmed tornadoes in the latest window. Slight Risk closed with the overnight line.

Pulse Table

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 parts of Oklahoma and northern Texas 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.

What This Is Not

This is not a Quiet Pulse. WPC Moderate Risk remains live over West Texas. Not a Slight or higher severe day. Not a tropical threat to the U.S. coast or Gulf. Not a named-storm hub update (no U.S.-threatening cyclone).

Looking Ahead One Day

SPC Day 2 outlook (0600 UTC) carries a Slight Risk of severe thunderstorms over a portion of the Mid-Atlantic for Friday afternoon and evening (mainly damaging winds, isolated tornado possible near the Delaware River Valley and Delmarva). WPC Day 2 continues a Moderate Risk of excessive rainfall across portions of West Texas as the front’s progression sustains the moisture axis. Pattern shifts southward; residual Oklahoma flood threat diminishes later today into Friday. No U.S. tropical development indicated.
