KEY MESSAGES

-Cool and gusty conditions expected tonight.

-Dry and cool Thursday, then a warming trend is seen through the weekend before another front cools temperatures for early next week.

SHORT TERM

(Tonight through Thursday night) Issued at 110 PM CDT Wed Mar 11 2026

An upper low is moving over South Central Texas early this afternoon which is evident on satellite with some wrap around clouds moving in from the north over over the southern Edwards Plateau. The main line of showers and thunderstorms from this morning has moved east of the area with predominantly dry conditions expected the rest of the day. Only low PoPs remain over the northeastern portion of our coastal plain counties late this afternoon given forcing from the upper low and a southward moving Pacific front. A quick shower or isolated thunderstorm could develop but no severe weather is expected.

The aforementioned cold front will make its way through the area today with gusty northerly wind behind this feature. The pressure gradient remains tight as the upper low ejects east and surface high pressure drops into North Texas tonight. Gusty wind will continue over the area overnight with gusts approaching 35-40 mph at times, only dropping off in the west after midnight. With cooler air moving into the region behind the front, wind chill values will drop down into the low to mid 30s over the Hill Country and southern Edwards Plateau and into the upper 30s to upper 40s elsewhere.

Surface high pressure will reside over the area by tomorrow afternoon bringing lighter wind and clear skies with cooler highs in the 60s to low 70s. Clear skies and light wind remain Thursday night into Friday bringing lows down into the 40s across all of South Central Texas.

LONG TERM

(Friday through next Wednesday) Issued at 110 PM CDT Wed Mar 11 2026

High pressure shifts east of the area Thursday night with southerly flow back in place by Friday. A day by day warming trend is expected through Sunday when highs peak from the upper 80s to mid 90s. If you're not ready for summer quite yet, then good news arrives in the form of a strong cold front making its way across the area Sunday night. Gusty wind behind the front will usher in cooler temperatures with highs Monday forecast in the 60s. Temperatures fall into the 30s and 40s Monday night, then another warming trend is seen through the end of the forecast. Dry weather is expected into the middle of next week.

AVIATION

(18Z TAFS) Issued at 110 PM CDT Wed Mar 11 2026

VFR conditions are expected at area TAF sites through the current forecast period. Daytime heating along with an upper low in the region will help SCT clouds develop for the I-35 sites. Cloud bases are expected to remain around 5K AGL. We will continue to monitor for some isolated convection near the base of the upper low, but for now we will not mention in the AUS forecast as confidence is low. Gusty west to northwest winds are in store this afternoon, with winds increasing and trending more northerly by late afternoon. Gusty conditions will continue overnight and into mid-morning Thursday, with decreasing winds in the late morning and afternoon.
