- Moderate to Extreme risk of heat-related impacts through next week, with peak heat indices 108 to 112.

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

DISCUSSION

Issued at 1228 AM CDT Fri Aug 14 2026

Expect Mid-level ridging to continue dominating the period leading to warm and mostly rain free conditions outside of isolated seabreeze convection each day. Overnight into this morning, we will see an inverted trough with some associated vorticity tracking along the southern periphery of the ridge pushing onshore. 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- 30%) 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

(12Z TAFS) Issued at 624 AM CDT Fri Aug 14 2026

VFR conditions have held so far this morning, and likely will through day-break, but will keep the mention of brief MVFR CIGS possible for the next couple of hours as often happens. Otherwise expect mainly VFR conditions through the rest of the period. Will have low chances for showers and storms today, mainly around VCT. Did add a VCSH for VCT site late morning and into the afternoon. Other sites have too low probability to include mention.

MARINE

Issued at 1228 AM CDT Fri Aug 14 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. The current Small Craft Advisory will expire at 1 AM. SCEC conditions will persist through 7 AM. Rain chances (20-30%) will be on the rise over the nearshore and offshore waters Thursday evening into Friday afternoon.

FIRE WEATHER

Issued at 1228 AM CDT Fri Aug 14 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. Didn't issue a Fire Danger Statement, though elevated fire weather conditions will remain possible in the Brush Country.
