KEY MESSAGES

- Low stratus this morning across central and western portions of the region with patchy fog possible mainly for locations south and west of San Antonio

- Rapid return to unseasonably warm and dry weather Monday and Tuesday.

- Rain chances return to South-Central Texas by the middle of next week.

UPDATE

Issued at 401 AM CDT Sun Mar 29 2026

Short term guidance over the last few hours has become a little less bullish on the fog, with focus now mainly south and west of San Antonio. A deck of Low stratus will still favor the central to western portions of the region.

SHORT TERM

(Today through Monday) Issued at 1219 AM CDT Sun Mar 29 2026

A broad upper level ridge stretches across the southern part of the country tonight. High pressure at the surface is producing light to near calm winds. Temperatures across the CWA are in the 50s and 60s and dewpoints are in the 40s and 50s. The light winds and just enough shallow low-level moisture will allow for a low stratus deck and perhaps some patchy fog this morning, favoring a region from Rocksprings through the San Antonio metro to near Cuero. Southeasterly winds will return today beginning the next warm up. Once this flow is established, it will continue through this period. The upper ridge will keep the weather dry, and temperature will warm each period. Back into the 80s today and some 90s Monday.

LONG TERM

(Monday night through Saturday) Issued at 1219 AM CDT Sun Mar 29 2026

The warming trend will continue into the middle of the week. Highs will be back in the 90s Tuesday except in Hill Country and Southern Edwards Plateau. Dry weather will continue. Models are showing a pattern change starting mid-week. Wednesday a dryline may generate showers and thunderstorms. Then an upper trough will bring another cold front through the region. This will bring another chance for showers and thunderstorms Thursday. Right now this looks like the best chance we've had for significant rain in quite some time. After a break on Friday another, possibly stronger, front will move in Saturday bringing another chance for rain.

AVIATION

(12Z TAFS) Issued at 544 AM CDT Sun Mar 29 2026

A low stratus deck with MVFR to IFR ceilings has established over the central half of the region, including at KSAT and KSSF. The stratus will slowly build westward and may bring MVFR ceilings briefly to KDRT after sunrise. KAUS stays VFR as these low clouds stay to the west. The short term guidance is now less bullish on fog with the best focus for any now occurring towards the south and west of San Antonio. VFR flight conditions will return by afternoon with moderate to breezy south to southeasterly winds expected. Gusts into the 20 to 25 kt range will be possible. The winds are to subside from the overnight into early Monday morning with returning low clouds. MVFR to IFR ceilings return with the low clouds.
