KEY MESSAGES

- Coolest day of the week today with dry weather and clear skies.

- Much warmer conditions then establish with well above average temperatures for the weekend through next week.

SHORT TERM

(Today through Saturday) Issued at 1204 AM CST Fri Dec 19 2025

Cooler, drier air continues to filter into South Central Texas behind a cold front early this morning. Surface high pressure will be centered over the area by sunrise with light wind and the chilliest morning lows of the week from the mid 30s to low 40s. High pressure is short lived, however, as it moves off to the east today bringing back southeasterly flow by the afternoon. Winds may be breezy at times today, especially in the higher elevations of the Hill Country and southern Edwards Plateau. Otherwise, expect a mild day with highs from the mid 60s to low 70s.

Southerly flow continues overnight and Saturday allowing for warmer temperatures to return to the area. Lows will mainly be in the 40s Friday night into Saturday. Some areas of fog may also return mainly east or south of I-35 Saturday morning. Highs jump into the mid 70s to low 80s with breezy wind developing over the eastern half of the area during the afternoon on Saturday as the pressure gradient increases ahead of a weak cold front.

LONG TERM

(Saturday night through Thursday) Issued at 1204 AM CST Fri Dec 19 2025

A weak cold front begins to move into the area early Sunday morning and stalls across our southeastern CWA Sunday into Monday. This will allow for slightly cooler temperatures in the northern half of the area with continued warm temperatures in the south. A few models try and develop some light precipitation with this feature Sunday night or early Monday in the coastal plains, but continued a dry NBM forecast due to low confidence. Temperatures warm right back up into 70s to low 80s where they remain for the rest of the long term period as mid-level ridging builds over the area and remains nearly stationary. Highs may be close to daily records some days. Increased low level moisture will lead to overnight cloudiness each night also keeping lows in the 50s to low 60s next week.

AVIATION

(06Z TAFS) Issued at 1204 AM CST Fri Dec 19 2025
