LONG TERM

(Saturday through next Thursday) Issued at 1213 PM CST Thu Jan 29 2026

The real chunk of this arctic airmass will move through the area Saturday and Saturday night, with temperatures not getting out of the 40s for highs Saturday afternoon. A surface high will result in light winds and primarily clear skies which is supportive of strong radiational cooling and cold temperatures Saturday night. It is expected to be the coldest night of the week with the NBM giving the Hill Country, I-35 Corridor, and Coastal Plains a 30-40% chance of lows less than 20 degrees. A few spots may drop to that number or below, but for the most part, lows in the lower to middle 20s can be expected across South Central Texas.

Sunday will start the slow and steady warm-up for the first few days of February. Southwesterly surface flow should resume by the afternoon in the wake of the departing surface high to our east. Monday and Tuesday look rather nice, with highs climbing back into the 60s and lower 70s. Our next weather maker is progged to arrive Tuesday afternoon as a weak disturbance in the southern stream works its way east out of northern Mexico Tuesday evening. Rain showers are possible as early as Tuesday evening and may continue through Wednesday before things dry out Thursday. Medium range guidance has struggled with the evolution of the northern stream jet Wednesday and beyond, so for now, will continue carrying low end PoPs until better agreement comes in on the evolution of the large scale pattern.

AVIATION

(18Z TAFS) Issued at 1213 PM CST Thu Jan 29 2026

A cluster of low level clouds developed across the southern Edwards Plateau this morning and pushed over the KSAT area around 17Z. Those low clouds since then dissipated for VFR conditions across the area terminals for the rest of today into Friday. Winds are forecast to shift from the west to northwest to north across most areas across South Central Texas as a cold front pushes across the local area. North winds of 10 to 15 knots with gusts of 20 to 25 knots are possible along and behind the frontal boundary this evening and overnight. Breezy north winds continue through Friday morning.
