992 FXUS64 KEWX 050609 AFDEWX Area Forecast Discussion National Weather Service Austin/San Antonio TX 1209 AM CST Fri Dec 5 2025 ...New SHORT TERM, LONG TERM, AVIATION... .KEY MESSAGES... - Low rain chances continue through this afternoon for most of south-central Texas along with below normal temperatures. - Much warmer Saturday, with another cold front moving in Sunday. Temperatures generally remain at or above normal through the remainder of the period despite another cold front mid-week. && .SHORT TERM... (Today through Saturday) Issued at 1201 AM CST Fri Dec 5 2025 05/00Z RAOB from DRT shows deep layer southwesterly flow aloft in place from 700mb above, with plenty of moisture from just above 700mb to 200mb. The 00Z sounding also showed a fair amount of dry air below 700mb except for a thin layer of moisture near 850mb. Radar returns are starting to pick up slowly across the Rio Grande plains, with only a few spots reporting light rain early this morning. Rain chances today will be favored from the Rio Grande plains eastward into portions of the I-35 corridor and coastal plains where moisture levels will be a little higher. Overall rainfall amounts will remain low, with mainly one-tenth of an inch or less. A few spots in the coastal plains (east of I-37/south of I- 10) could see some one-quarter inch amounts. Cloud cover remains thick, so daytime highs will mostly remain in the 50s, with near 60 along the Rio Grande. Clouds persist into tonight as rain chances shift east of the region. Look for overnight lows in the 40s. Winds trend to a more southwest to westerly direction on Saturday as clouds decrease from west to east. Highs will quickly warm into the 70s with perhaps a few upper 60s along the Highway 77 corridor. && .LONG TERM... (Saturday night through Thursday) Issued at 1201 AM CST Fri Dec 5 2025 Another cold front will move into south central Texas Sunday morning, with some cooler temperatures in store for the Hill Country and nearby I-35 corridor. Farther to the south, the low- level thermal ridge will be slow to erode and with downslope northwesterly winds, highs will likely be able to warm into the mid and upper 70s for areas generally along and south of Highway 90/I-10. Clear skies, dry air and decreasing winds should drop overnight lows to near freezing across the Hill Country and southern Edwards Plateau Monday morning. Surface ridging in place on Monday will yield highs below normal with upper 50s to mid 60s expected. Southerly winds return Tuesday bringing highs closer to climatological normals for this time of year. There are some timing differences noted among the operational models with respect to the arrival of the next cold front sometime on Wednesday or early Thursday. The GFS and Canadian are trending faster than the ECMWF, so we will continue to monitor for temperature forecasts on Wednesday into Thursday. && .AVIATION... (06Z TAFS) Issued at 1201 AM CST Fri Dec 5 2025 MVFR to VFR flight conditions are to begin the period but most locations, including the TAF sites, improve to VFR conditions by sunrise with mainly a BKN to OVC deck of mid to high level clouds. There will be occasional patches of light rain across the region through early afternoon but this is not expected to have any flight impacts. Light winds of 8 kt or less prevail with directions shifting from northerly to southerly for most locations outside of the Rio Grande. Locations closer to the Rio Grande, including KDRT, should see the light winds more out of the east and east-southeast. && .PRELIMINARY POINT TEMPS/POPS...
