KEY MESSAGES

Issued at 1236 AM CDT Thu Aug 13 2026

- Moderate to Extreme risk of heat-related impacts through next week, with peak heat indices 110 to 115, especially today and Thursday.

- Borderline elevated fire weather conditions over the Rio Grande Plains daily.

- Little to no rain chance through Thursday, limited 20% Friday.

DISCUSSION

Issued at 1236 AM CDT Thu Aug 13 2026

We will continue to see mid-level ridging dominating the period leading to warm and mostly rain free conditions outside of isolated seabreeze convection each day. As we approach Thursday night into Friday morning, we will see an inverted trough with some associated vorticity tracking along the southern periphery of the ridge. This will lead to an influx of moisture in the region, surging PWATs around 2.0 inches (75th percentile of climatology). Due to these factors coupled with small scale lift will allow for low rain chances (~20%) during the morning into the afternoon on Friday.

Will continue to monitor the need for short-fused heat related products. We could see peak heat indices of 110 to 115 with dew points in the mid to upper 70s into next week. This translates to moderate to predominately major HeatRisk conditions, though some areas of extreme HeatRisk will be possible in the Brush Country. An additional risk for elevated fire weather exists over the Rio Grande Plains into the next week due to low RH (<30%) and sustained 20 mph winds gusting up to 30 mph. We strongly encourage the practice of heat safety in these conditions. Take frequent breaks and remember to stay hydrated, check those backseats, and avoid long exposure in these temperatures.

AVIATION

(06Z TAFS) Issued at 1236 AM CDT Thu Aug 13 2026

Winds will remain a bit elevated through the night, though have lost the gusts for eastern sites and will lose gusts west later in the night. Near moderate winds persist and will limit any vis reductions. Mostly VFR conditions are expected with little moisture in the lower levels, though ALI could briefly see MVFR toward morning.

MARINE

Issued at 1236 AM CDT Thu Aug 13 2026

Moderate to occasionally fresh southeasterly flow will persist through this week for most of the waters. Bays and waters along the coast south of Port Aransas will have a fresh breeze during the afternoon and evening hours through Friday. A Small Craft Advisory may be needed over this period. Rain chances (~20%) will be on the rise over the nearshore and offshore waters Thursday evening into Friday afternoon.

FIRE WEATHER

Issued at 1236 AM CDT Thu Aug 13 2026

Min RHs will be in the 20-30% range each afternoon into the weekend in the western Brush Country and Rio Grande Plains. Low RHs, ERCs in the 70-89th percentile range, and gusty winds will lead to elevated fire weather conditions over this region. Another Fire Danger Statement was issued for today from 1 PM through 9 PM.
