331 FXUS64 KEWX 030617 AFDEWX Area Forecast Discussion National Weather Service Austin/San Antonio TX 1217 AM CST Wed Dec 3 2025 ...New AVIATION... .KEY MESSAGES... - Cool weather continues through Friday. - Scattered rain showers Wednesday afternoon through Thursday and Friday. - Drier and warmer weekend weather. && .SHORT TERM... (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... (06Z TAFS) Issued at 1210 AM CST Wed Dec 3 2025 With surface dew point values in the low 30s, it will take some time for the return flow to get clouds back into the I-35 corridor. VFR skies should make it through around 12Z around SAT/SSF, and probably a couple hours later for AUS. First guess is a low MVFR CIG upon arrival, but can`t rule out IFR or LIFR cigs and fog briefly at daybreak. Steady S/SSW boundary layer winds will continue deepening the Gulf moisture layer, so we`d expect an MVFR CIG to carry out through the afternoon. Moisture continues to deepen into the evening, and there looks to be enough pooled moisture and WSW flow aloft to support some light shower activity or drizzle through the evening. A cold front could approach AUS by around 06Z and possibly bring better mixing to lift CIGs and VSBYs slightly. && .PRELIMINARY POINT TEMPS/POPS...
