KEY MESSAGES

Updated at 535 AM CDT Fri Aug 14 2026

- Hot and mostly dry summer weather continues this week. Practice heat safety and stay cool and hydrated.

SHORT TERM

(Today through Saturday) Issued at 1201 AM CDT Fri Aug 14 2026

Mid-level ridging remains in control early this morning and is expected to lead to continued hot and dry weather through the next week. In the short term, afternoon highs and associated heat indices have been right around Heat Advisory thresholds, but not widespread enough to warrant the issuance of one. Once again, Thursday will feature highs in the upper 90s to around 105 along the southern Rio Grande Plains. Heat indices will hover between 103-107 with a few spots, particularly in the Coastal Plains briefly touching 108-109 this afternoon. A weak disturbance rounding the base of the ridge will send some low level moisture inland this afternoon, primarily along and east of the I-35 Corridor, where we will carry 20 PoPs this afternoon and early evening. A brief heavy downpour or two along with an isolated thunderstorm is possible but not much beyond that. On Saturday, hot and dry weather resumes with highs in the mid 90s to 103 along with heat indices in the 102-108 range.

LONG TERM

(Saturday night through Thursday) Issued at 1201 AM CDT Fri Aug 14 2026

Sunday and beyond, the mid-level ridge slides further west and closes off any sort of window of opportunity for showers or storms. Highs each day Saturday through Tuesday will top out in the mid to upper 90s to around 103. Long range guidance from the CFS does indicate a bit of a quick switch to a more active pattern as El Nino takes shape this Fall in the months of September and October, but we will have to wait and see how things evolve over the next few weeks.

AVIATION

(12Z TAFS) Issued at 535 AM CDT Fri Aug 14 2026

Areas of MVFR ceilings have developed near the I-35 corridor this morning but are not widespread. KSAT will likely see the most consistent MVFR conditions, with KSSF and KAUS bouncing between SCT and BKN ceilings. A few hours of MVFR ceilings is still possible at KDRT. Around 15Z, sites will return to VFR and remain that way through tonight. Gusts from 20-25 knots will be seen across much of the area this afternoon into the evening. MVFR ceilings redevelop tonight into Saturday morning.
