(Today through Thursday) Issued at 1248 AM CDT Wed Oct 8 2025 A weak cold front will move into the region today, with drier air filtering into the Hill Country, I-35 corridor, and inland Coastal Plains. Higher moisture values will remain pooled today from the western Hill Country, southern Edwards Plateau, and Rio Grande, southward into South Texas. HREF members are consistent with isolated shower development through this region this afternoon. The drier air pushes farther south, through the area, on Thursday. Warm conditions continue, with high temperatures in the upper 80s to mid 90s and low temperatures in the mid 60s to low 70s. && .LONG TERM... (Thursday night through Tuesday) Issued at 1248 AM CDT Wed Oct 8 2025 Ridging aloft will remain over the region Friday through the weekend. In the lower levels, expanding high pressure to the northeast allows even drier air to backdoor into the region, with precipitable water values of only 0.7-1.1 inches indicated Friday and Saturday. Lower dew points and mostly clear skies will allow for large diurnal swings in temperatures Friday through Sunday. Low temperatures Saturday are forecast to dip into the 50s for many areas, outside of the urban San Antonio and Austin metro areas and Rio Grande where lows in the lower 60s are forecast. Highs Saturday are forecast to rebound to a warm upper 80s to lower 90s, but low relative humidity. Southerly low level flow resumes Sunday, and low level moisture is forecast to gradually increase especially Sunday night into Monday. This should result in increasing humidity and smaller diurnal wings in temperatures Monday and Tuesday. && .AVIATION... (06Z TAFS) Issued at 1248 AM CDT Wed Oct 8 2025 VFR flight conditions are to prevail across the TAF sites through the period. A surface boundary across the region continues to help generate a couple brief rain showers at the time of this discussion but this will likely wane within the next or two. Confidence is too low for any shower to impact the TAF sites for inclusion of VCSH or SHRA overnight. Otherwise, expect for few to bkn mid-level clouds across the region with low clouds focusing farther south and into portions of the Rio Grande Plains. Any MVFR ceilings should focus south of the terminals but a few low clouds may reach DRT. DRT could see a spotty shower chance in the afternoon and is enough to insert VCSH within the TAF. The rest of the sites should remain rain free. Winds during the afternoon through the early evening will trend out of the northeast up near 10 kts. Light and variable conditions otherwise trend overnight into the morning. && .PRELIMINARY POINT TEMPS/POPS...
