KEY MESSAGES
Updated at 603 AM CDT Wed Aug 12 2026
- Hot and mostly dry summer weather continues this week. Practice heat safety and stay cool and hydrated.
SHORT TERM
(Today through Thursday) Issued at 1257 AM CDT Wed Aug 12 2026
The Subtropical ridge has become a bit more disjointed this evening, but don't be fooled. Despite it's appearance on GOES East imagery, it is expected to maintain control over our ambient weather for the foreseeable future. High temperatures today and tomorrow will range from 95 over the Hill Country, to 100-102 along the I-35 Corridor, to 102-105 over the Rio Grande Plains. Surface dewpoints should start to mix out, but heat indices will climb into the 102-107 range, particularly along the I-35 Corridor eastward through the Coastal Plains. Thursday will be a virtual carbon copy of today with some morning clouds followed by a hot and dry afternoon.
LONG TERM
(Thursday night through Tuesday) Issued at 1257 AM CDT Wed Aug 12 2026
Subtropical ridging won't budge much in the long term, primarily setting up shop over the Southeastern CONUS, south central Texas will remain hot and dry through the next week. Temperatures will climb into the mid to upper 90s with some 100-104 temps sprinkled in. Heat indices should actually trend down a bit by the weekend into early next week as soils continue to dry out.
AVIATION
(12Z TAFS) Issued at 603 AM CDT Wed Aug 12 2026
MVFR CIGs are surrounding the I-35 TAF sites in SCT V BKN fashion and should be an impact up to around 15Z. Gusty winds could be as high as 28 knots in the afternoon and early evening. MOS guidance shows the near persistence diurnal wind and CIG trends should continue with low amounts of decoupled winds in the morning and gusty daytime winds in the afternoon and evening.
