970 FXUS64 KEWX 222024 AFDEWX Area Forecast Discussion National Weather Service Austin/San Antonio TX 224 PM CST Wed Jan 22 2025 ...New SHORT TERM, LONG TERM... .SHORT TERM... (Tonight through Thursday night) Issued at 207 PM CST Wed Jan 22 2025 Key Messages: - Hard freezes continue tonight and Thursday night - Continued cold mornings but slow warmup in progress Tonight expect cloudy to partly cloudy conditions with another hard freeze likely as temperatures drop down into the upper 20s. Add in a light wind and windchill values once again are quite cold though they look to stay JUST above our Cold Weather Advisory Criteria. Should these northerly winds come in stronger overnight we may have to issue another Cold Weather Advisory especially for the Hill Country. Tomorrow we look to warm up slightly more then we managed to today with highs generally in the low to mid 50s. Another cool night is on tap for the area with a Hard freeze expected as temps tumble into the upper low to mid 20s. && .LONG TERM... (Friday through Wednesday) Issued at 207 PM CST Wed Jan 22 2025 Key Messages: - Warming up this weekend with more seasonable temperatures in the 50s/60s. - Several rain chances return with a more active pattern returning Sunday through the middle of next week. A surface high will slide east on Friday afternoon, allowing surface flow to turn back out of the southwest and become quite breezy, resulting in some elevated fire weather conditions, particularly over the Rio Grande Plains and Southern Edwards Plateau where RH values dip into the 20-25% percent range and winds increase to 10-15 mph. Temperatures will remain on the cooler side, in the 50s, but warmer temperatures are on the way this weekend as southerly flow increases and moisture return commences. Our best shot at rain in the 7 day period arrives Sunday with a frontal boundary pushing south into the region and moist southeasterly surface flow ahead of the boundary resulting in good isentropic upglide to produce showers and perhaps a few thunderstorms in the afternoon. At this time, it looks like primarily a I-35 Corridor and Coastal Plains event with more than likely less than a half inch of QPF. All precip should be in liquid form. A brief break commences on Monday before a cutoff low develops over the southwestern CONUS and takes its sweet time ejecting out over the southern plains states this week. That will result in continued southwest flow aloft and a bit of a messy pattern with rain chances increasing Tuesday and Wednesday. For now, we will keep PoPs capped at 50% for Sunday and at 40% for Tuesday and Wednesday as confidence isn`t particularly high in the long wave pattern in the medium to long range. No sign of additional arctic air in the long term forecast at this time. && .AVIATION...
