(Tonight through Thursday night) Issued at 1206 PM CST Wed Dec 10 2025 Breezy winds continue to spread across the area as a batch of stronger momentum trailing behind a cold front diffuses over South- Central Texas. Gusts mainly within the 20 to 30 mph range should persist through the afternoon but will start to taper as the high momentum air mixes out. Surface high pressure in the wake of the cold front will steadily move across South-Central Texas tonight. Winds are expected to weaken to a near calm for most of the area, combining with clear skies and dry conditions for a night of efficient radiational cooling. Morning lows Thursday morning are forecast to be in the mid 30s to low 40s. Most should stay above freezing, though there may be an isolated patchy dip into the low 30s in low-lying drainage areas in the southern Edwards Plateau and Hill Country. A southerly flow returns Thursday with ample sunshine continuing, though slightly cooler low-level temperatures will keep highs generally around 70. The impact of those southerly winds will be better felt by Thursday night, with overnight lows only reaching the mid 40s to low 50s as Gulf moisture boosts dew points, including medium chances (around a 40 to 60 percent chance) of some advection fog Thursday night into Friday morning over the Coastal Plains. && .LONG TERM... (Friday through next Wednesday) Issued at 1206 PM CST Wed Dec 10 2025 Persistently southerly to southwesterly flow entering this weekend will support high temperatures reaching levels well above seasonable for Friday. Highs are forecast to be in the mid to upper 70s over most of the CWA. A weak front could approach the area Saturday and moderate temperatures slightly, but above average warmth is still anticipated. Moist southerly flow continuing at the low-levels may support a few isolated showers primarily over the Coastal Plains Saturday. A stronger cold front is forecast to arrive from the north Sunday, bringing cloudier skies and more noticeably cooler air and breezy conditions. The coldest air will be well to our northeast (over the Midwest and eastern US), so temperatures for our area mostly drop to seasonable to slightly cooler than seasonable levels for Sunday and Monday with a low chance (up to 20 percent) of a freeze Monday morning. A few showers and an isolated thunderstorm are possible along and ahead of the front Sunday south of I-10, but the drawn out frontal surface, lack of strong frontogenesis, and weak synoptic forcing keeps rain chances low... around 20 to 30 percent mainly for the Rio Grande Plains. Ridging aloft rebuilds over the area Tuesday, facilitating a warming trend starting Tuesday. Ensembles are in fair agreement that a disturbance currently over the open eastern Pacific will reach the southern US by about midweek. This supports an increase in rain chances Tuesday and Wednesday, though uncertainties with timing keeps rain probabilities low (around 20 percent) for the time being. && .AVIATION... (18Z TAFS) Issued at 1206 PM CST Wed Dec 10 2025 VFR conditions are in store at area TAF sites through the current forecast period. Gusty north winds behind a cold front will continue to spread southward today and remain intact until roughly 00Z. We should then see both sustained winds and gusts drop off through the evening hours and into the overnight period. Mainly light winds will be in place Thursday, with winds returning to a more southeast to southerly direction in the afternoon. && .PRELIMINARY POINT TEMPS/POPS...
