(Tonight through Wednesday night) Issued at 1120 PM CST Tue Dec 2 2025 West-southwesterly mid-level flow continues to send Pacific moisture into the region in the form of mid to upper level clouds this evening. Mostly dry weather is expected today with the exception possibly being over the Coastal Plains late this afternoon through Wednesday night as surface moisture increases ahead of the next approaching trough. Showers and perhaps a rumble of thunder will develop over the Coastal Plains towards sunset Wednesday and primarily remain over this region through early Thursday morning. A long wave trough approaches the Panhandle on Thursday, sending a series of weak shortwaves through the west- southwesterly flow aloft. This will result in much cooler temperatures Thursday along with showers and some isolated thunderstorms through the day. && .LONG TERM... (Thursday through next Tuesday) Issued at 1120 PM CST Tue Dec 2 2025 The aforementioned trough will remain stretched out over the Baha of California on Friday, resulting in continued surface moisture teaming up with a mid-level disturbance and moisture to produce showers again on Friday. This long wave trough should finally eject out over the southern plains on Saturday, allowing a nice drying and warming trend for the weekend. Beyond the weekend, a warmer than normal pattern is expected to develop through the middle of December with minimal rain chances. && .AVIATION... (12Z TAFS) Issued at 537 AM CST Wed Dec 3 2025 Gulf moisture return is slightly ahead of schedule in bringing SCT V BKN MVFR CIGS into the I-35 Corridor. The VAD winds would suggest they will remain well east of DRT for today, but we should see 1000-2500 FT CIGs to fill in to become a thicker OVC layer the deeper we go into the daytime. By this evening we should see the CIGs dropping possibly to IFR by 00Z and possibly even into LIFR or lower at times late in the evening. DRT should expect to see some low clouds spread their way as a reinforcing cold front arrives. This front should get to AUS shortly after 06Z and into the SAT/SSF areas roughly an hour or two later. Timing of when the winds kick up and raise CIGs and VSBYs slightly may not coincide with the actual front arrival, but rather be delayed an hour or two. With the light isentropic lift over the front the likelihood of prevailing rain over I-35 increases, with AUS most likely to see impacts before daybreak. && .PRELIMINARY POINT TEMPS/POPS...
