Temperatures remain a little below normal on Monday, with a warming trend into the middle of next week. && .SHORT TERM... (Tonight through Friday night) Issued at 1149 AM CST Thu Dec 4 2025 South Central Texas remains under overcast skies today keeping cool and dreary conditions around the area. Late this morning, a few locations are still reporting some light rain or drizzle though visibility has improved across all locations. Our overrunning pattern producing wet and drizzly conditions this morning is forecast to weaken which will allow for drier conditions this afternoon with cool temperatures from the low 50s to low 60s. Expect mainly dry conditions to continue through early Friday morning, then precipitation increase after sunrise as some mid-level disturbances pass over the area. Chances for light rain and drizzle increase first over the Rio Grande then extend east through the morning into the early afternoon before decreasing late afternoon. Rain amounts will be highest in the western and southern reaches of the CWA but may only amount to around a quarter of an inch over portions of the southern Edwards Plateau, Rio Grande Plains and Coastal Plains south of San Antonio. Elsewhere, rain amounts will vary from a few hundredths up to a tenth of an inch. Some local reductions in visibility are also expected in the morning hours Friday with this activity. Highs remain on the cool side tomorrow topping out in the 50s across the area. && .LONG TERM... (Saturday through next Thursday) Issued at 1149 AM CST Thu Dec 4 2025 Drier air gradually begins to move over the area Friday night into the weekend bringing an end to rain chances for South Central Texas. Cloudy skies overnight will clear up from the northwest to southeast Saturday allowing highs to warm up into upper 60s to mid 70s. Winds turn northerly Sunday behind a dry cold front which moves across the area in the morning. This will lead to cooler high temperatures in the north from the low to mid 60s to warmer temperatures in our southern CWA in the low to mid 70s. Winds will be breezy Sunday and Sunday evening but decrease Sunday night into Monday. Early Monday morning, a few locations in the Hill Country or southern Edwards Plateau may briefly see freezing temperatures, but this will likely be for locations who have already seen a freeze this season. Surface high pressure keeps light wind, clear skies and mild highs in the upper 50s to mid 60s around on Monday. This high pressure then shifts east Tuesday with northwesterly flow setting up aloft. Dry weather is forecast for the rest of the period warmer temperatures in the 60s and 70s. && .AVIATION... (00Z TAFS) Issued at 543 PM CST Thu Dec 4 2025 Expect somewhat better flying conditions for this forecast package though some MVFR cigs remain mainly over KAUS and KSAT at this hour. Have added a TEMPO for KSAT and KSSF for MVFR cigs as expect a mix of VFR and MVFR for a few more hours before improving to VFR cigs. MVFR cigs are expected for KAUS throughout the overnight hours before improving to VFR cigs. For all I-35 TAF sites expect northerly winds of 10-15kt with some gusts up to 20kt before becoming light and eventually switching to the south by tomorrow. Rain chances increase once again tomorrow but cigs should generally stay MVFR this time. Have kept PROB30s to account for this. For KDRT expect VFR cigs to continue before rain chances and MVFR cigs commence by morning and have kept PROB30s for this as well. && .PRELIMINARY POINT TEMPS/POPS...
