KEY MESSAGES

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

- Active weather pattern may return to South Central Texas by the middle of next week.

SHORT TERM

(Tonight through Saturday night) Issued at 103 PM CDT Fri Mar 27 2026

As has been the case over the past few model runs, the front has sped up significantly. As seen via observation metars and visible satellite imagery the front is located just north of a Del Rio to Rocksprings to Llano line. Areas out and ahead of this front should expect to see highs reach the 80s along the I-35 Corridor and upper 80s to near 90 in the Coastal Plains with low 90s expected over the Winter Garden area. Once this cold front moves through expect breezy northerly winds with gusts into the 30 to 35 mph range as temps continue to fall. We also could see some light showers or sprinkles in the wake of this front but most areas will likely remain dry. However we don't expect a rapid drop like the past few fronts we have seen. Temps will continue to fall throughout the evening and thus due to the faster front arrival have lowered low temperatures a few degrees as well. Many areas should see low in the 50s with areas across the Hill country dropping into the 40s. Additionally, winds will remain breezy overnight especially along ridgetops and higher elevation areas across the Hill Country and Southern Edwards Plateau. Saturday looks to remain cool across the area with CAA continuing before finally easing early in the afternoon. Because of this highs will struggle to get out of the 60s for the Hill Country with areas along and south of the I-35 Corridor eventually reaching the low 70s. Another cool night is in store for tomorrow night with many remaining in the 50s as southerly low level flow finally returns.

LONG TERM

(Sunday through next Friday) Issued at 103 PM CDT Fri Mar 27 2026

With southerly flow in place many areas should warm into the 80s Sunday followed by even warmer highs (near 90) by Monday. Warmer and dry weather continues Tuesday, but by midweek, things may finally get interesting as a mid-level shortwave swings through north Texas on Wednesday. Global models are having a difficult time regarding timing for our area so for the moment have kept pops more generally blended closer to the NBM with chances 20-30% until we get closer in time. Beyond midweek all signs point to a significant pattern change as the subtropical jet stream looks to become much more zonal along with high pressure sliding off to our east over the southeast US. This opens the door for a fetch of gulf moisture to approach our area allowing for any disturbances that move over us to tap into. While its too early to get into specifics at this time it does look like we could be seeing our dry pattern finally come to end.

AVIATION

(18Z TAFS) Issued at 1239 PM CDT Fri Mar 27 2026

Tricky forecast as the front has sped up significantly which has moved up the timing for gusty wind and low clouds behind this feature. North to northeast wind behind the front will increase fairly quickly with gusts from 20 to 30 knots expected. Low clouds are also seen behind the front, though there are some patches of clearer skies which may be seen off and on before widespread stratus moves over the area this evening and lingers into Saturday morning. Wind remains gusty through the overnight hours, then gradually weaken during the day Saturday. Some very light showers or sprinkles may also be seen overnight into Saturday, favored from the Hill Country and areas west. Due to the spotty nature of any precipitation, have excluded the mention of it in this forecast.
