KEY MESSAGES

- Dry weather pattern through next week.

- Day by day warming trend though the weekend with highs approaching daily records on Sunday.

- Strong cold front brings windy and cooler conditions Sunday night and Monday.

SHORT TERM

(Tonight through Friday night) Issued at 110 PM CDT Thu Mar 12 2026

Gusty wind this morning will continue to decrease through the afternoon as surface high pressure moves overhead today. Highs will be slightly below seasonable levels this afternoon, in the mid 60s to low 70s. For reference, normal high temperatures for March 12th are 79 at Del Rio, 73 at San Antonio, and 72 at Austin Camp Mabry. Light wind and clear skies will drop lows into the 40s across the region overnight. The surface high will be east of the area by Friday morning returning southerly flow over South Central Texas which lasts through the weekend. For Friday, this means about a ten degree bump in highs from today ranging from the upper 70s to the mid 80s in the afternoon.

LONG TERM

(Saturday through next Thursday) Issued at 110 PM CDT Thu Mar 12 2026

A warm weekend awaits with highs in the 80s and 90s both Saturday and Sunday, though Sunday wins out for the warmest temperatures of the week. Forecast highs Sunday approach or exceed daily records aided by compressional warming ahead of our next cold front Sunday evening.

The strong cold front still looks to quickly advance north to south across the area Sunday evening, though limited hi-res guidance this far out does suggest a slightly earlier onset that we'll have to monitor. Strong northerly wind behind this front, potentially Wind Advisory level, will usher in cooler temperatures with lows Monday morning as low as the 30s over the Hill Country and southern Edwards Plateau. Gusty north wind continues into the morning Monday bringing forecast wind chill values into the 20s over those same locations. Wind will decrease through the afternoon Monday as high pressure again moves over the region. Highs Monday have trended lower than the previous forecast with our northern areas now in the 50s and southern portions of the CWA in the low to mid 60s. Tuesday morning has the potential for some locations to see freezing temperatures, with the NBM currently giving about a 20-40 percent chance for temperatures less than 32 degrees over our typically colder locations of the southern Edwards Plateau and Hill Country.

From here, the surface high shifts east again returning winds back from the south for the rest of the week. At the same time, an anomalously strong ridge over the western US slowly builds east through next week increasing temperatures each day for the rest of the forecast.
