KEY MESSAGES

- Widespread clouds and a low chance for light rain for most areas Monday into Tuesday.

- Temperatures trend back to above normal mid to late week, with cooler temperatures late Friday into Saturday.

SHORT TERM

(Today through Tuesday) Issued at 1215 AM CST Mon Jan 12 2026

The 12/00Z sounding from Del Rio showed plenty of moisture in the 500-300mb layer with another area of moisture between roughly 700- 600mb. Earlier observations near Del Rio did show some light rain reaching the ground. Incoming models generally agree in showing the better chance for any measurable rainfall to remain over the Rio Grande plains into the southern Edwards Plateau region this morning. Rainfall amounts should generally remain one-tenth of an inch or lower, especially given the very dry air in the sub-cloud layer. Precipitation looks to increase in coverage and spread over our area tonight into Tuesday morning as an upper level low approaches from the west. The best chances will be over western Hill Country and the I-37 corridor west to the Rio Grande.

LONG TERM

(Tuesday night through Sunday) Issued at 1215 AM CST Mon Jan 12 2026

The above mentioned upper low opens and moves east of our region late Tuesday, so we will keep the forecast dry for Tuesday night. Again, we don't expect to see any significant rainfall amounts, but anything will be welcomed given the lack of rainfall over most of the region. Clouds decrease and a quick warmup will commence for most areas on Wednesday. A Pacific cold front will move through the region Wednesday afternoon, so we will keep highs closer to climatological normals in the southern Edwards Plateau and Hill Country, with above normal highs elsewhere. Surface high pressure builds in from the north Wednesday night and with clear skies and dry air in the lower levels a freeze is in store for the Hill Country and southern Edwards Plateau.

On Thursday, surface high pressure quickly slides southeast of the region and with a surface low developing over the Panhandle, southerly winds will return to most areas. Highs on Thursday should remain near normal, but will trend above normal on Friday. Another cold front will move in Friday, with some disagreement noted among the latest round of global models on how quickly the front moves across south central Texas. We may need to trim back on forecast highs across the Hill Country if the faster Canadian and ECMWF solutions verify. The last few runs of both the operational GFS and ECMWF has trended upward with temperatures for the upcoming weekend. We will keep highs near to just below normal on Saturday, with temperatures trending to several degrees above normal on Sunday.

AVIATION
