FXUS64 KEWX 221735 AFDEWX Area Forecast Discussion National Weather Service Austin/San Antonio TX 1235 PM CDT Wed Apr 22 2026 ...New AVIATION... .KEY MESSAGES... - Level 1 of 4 risk for excessive rainfall over the Coastal Plains today. - Showery weather continues through Wednesday evening. - Cool today with highs in the low to mid 80s with a warming trend for the latter part of the week, upcoming weekend, and early next week. && .SHORT TERM... (Today through Thursday) Issued at 132 AM CDT Wed Apr 22 2026 Light rain is likely to continue mainly along the I-35 Corridor overnight through at least noon Wednesday. Also, developing overnight, patchy to areas of fog across the I-35 Corridor and southern Edwards Plateau. Can't rule out a few places where visibility could drop to a half mile or so. Otherwise, Wednesday's highs are forecast to stay in the low to mid 80s for the most part. Shower and thunderstorm activity returns mainly for areas east of Intestate 35 and the Coastal Plains in the afternoon through early evening. With elevated pwats in place, can't rule a quick heavy shower or storm producing half to an inch of rainfall. Even though the forecast calls for dry conditions along the Rio Grande on Wednesday, like to mention that a few storms are likely to develop ahead of the dry-line and then move over northeast Mexico. With the steering flow being from west to east over that region, can't rule out some of these storms to get closer to the Rio Grande late afternoon into the evening. As the night progresses, an upper level northwest flow aloft takes place and reminds through Thursday morning before becoming a zonal flow. At the surface, southerly flow is forecast to stay in control and brings back the mid to upper 80s. && .LONG TERM... (Thursday night through Tuesday) Issued at 132 AM CDT Wed Apr 22 2026 Dry and warm conditions are forecast for Friday into the weekend. The Spring-like temperatures are back with highs in the mid to upper 80s and low 90s. Rain chances through this period are very little to none. However, any storm that manages to develop could produce heavy downpours as it taps into the moist southerly flow. Mornings are likely to be cloudy but those clouds break in the afternoon for at least partly cloudy skies. && .AVIATION... (18Z TAFS) Issued at 1230 PM CDT Wed Apr 22 2026 All sites should have lifted out of IFR CIGs by around 1830Z. Small streamer showers continue to provide extra humidity to hold some BKN CIGs into the next 2-3 hours, but area wide VFR conditions should be resuming by 21Z or 22Z with northern counties seeing the slower lifting of CIGs. High amounts of ground moisture and a moderate overnight wind could lead to more IFR CIGs after midnight tonight, but for now we are expecting enough late afternoon and evening mixing to preclude another night of dense fog. && .PRELIMINARY POINT TEMPS/POPS...
