SHORT TERM

(Tonight through Monday night) Issued at 1217 PM CST Sun Jan 11 2026

High clouds are covering South Central Texas early this afternoon and this trend continues for the rest of this afternoon. Today's highs are forecast to reach the upper 50s over parts of Val Verde County and southern Edwards Plateau and lower to mid 60s elsewhere. An upper level disturbance pushing up between northeast Mexico and southern Texas Plains may bring an isolated shower along the Rio Grande, but from the surface to about 10kft is dry, and likely evaporate before reaching the ground. However, later tonight into Monday morning, another upper level pulse of energy is forecast to push from northeast Mexico into the Rio Grande and produces light shower activity as the mid level atmosphere moistens. Overnight lows are not as cold as of last night with temperatures in the mid 30s across the Hill Country to the upper 30s and lower 40s for the rest of South Central Texas.

The pulse of energy moves across the southern Edwards Plateau and Hill Country on Monday morning and a few light showers are possible there. Otherwise, stays dry for the most part Monday afternoon under mostly cloudy skies with highs reaching the mid 50s to mid 60s. Can't totally rule out a passing shower or two across the southern Rio Grande mid to late afternoon as another pulse of energy travels across that region.

LONG TERM

(Tuesday through next Sunday) Issued at 1217 PM CST Sun Jan 11 2026

Chances for rain increase on Monday evening along the Rio Grande and then into the Hill Country and areas along Highway 281 through Tuesday morning as an upper level low pressure system over northern Mexico pushes into the southern portion of west Texas. The upper low is forecast to push to the southeast and opens as it moves across the local area. A cloudy start of the day across all areas turns partly cloudy from west to east as the upper low exits South Central Texas. Another cool day is in store for the local area with highs in the 50s and 60s.

Northwest flow loft takes over the local area Tuesday afternoon into the evening and continues through Wednesday to end chances of rain. A dry cold front pushes across South Central Texas on Wednesday and brings breezy northerly winds through the region. Highs are forecast to reach the upper 60s across the Hill Country and 70s as the frontal boundary pushes through the Coastal Plains.

Much cooler on Thursday and Friday before a stronger cold front pushes across the local area Friday evening. The airmass in the wake of this front stays over the weekend with lows reaching lower to mid 30s most locations on Sunday morning.

AVIATION

(00Z TAFS) Issued at 524 PM CST Sun Jan 11 2026

VFR ceilings are expected through the period. A brief lower of ceilings could approach 5 KFT at DRT with elevated showers expected to be focused in this region between 08Z and 15Z. The CIGs should remain above VFR, but based on some of the simulated reflectivity in the hi-res data, there could be a brief rainfall rate lowering VSBY to 5SM. Winds to remain light through the period, as a mainly N/NE wind goes variable, then light S/SE late in the TAF periods.
