NWS Austin/San Antonio, TX wrote its last area forecast discussion before the first event at Apr 30, 12:24 PM CST, 22 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service Austin/San Antonio TX 124 PM CDT Thu Apr 30 2026 ...New SHORT TERM, LONG TERM... .KEY MESSAGES... - Isolated to scattered thunderstorms are forecast for the rest of today into early Friday evening. Some could be strong to marginally severe. - Locally heavy rain is forecast to affect some locations across South Central Texas through early Friday evening and a Flood Watch has been issued. - Dry and cooler weather for the weekend with a warming trend forecast for the work week. && .SHORT TERM... (Tonight through Friday night) Issued at 114 PM CDT Thu Apr 30 2026 Latest visible imagery shows cloudy skies across most of South Central Texas with some breaks over the Coastal Plains. A mid to upper level shortwave moving across the Hill Country is helping shower and thunderstorm activity across the Hill Country especially over portions of Burnet, Blanco, and soon over Travis counties as of 1 PM CDT. This activity could be enhanced as the afternoon progresses with more activity expanding over parts of the southern Edwards Plateau. Main hazards are large hail, strong to damaging wind gusts, and localized heavy rain. We may have a lull in activity later this afternoon into the early evening, but showers and thunderstorms return over the Rio Grande mid to late evening and then move eastward overnight into Friday afternoon and possibly through early Friday evening. These storms will have the support of an upper level short wave pushing from Baja California into northern Mexico into west Texas and then over our local area throughout the day Friday. There is a moderate to high confidence on locally heavy rain across a good portion of South Central Texas late this evening through Friday evening as several rounds of heavy rain affect the local area. A Flood Watch is in effect from 9 PM CDT this evening through 9 PM CDT Friday. Rainfall amounts of 2 to 4 inches are forecast with isolated 6 inches for the duration of the Flood Watch. Remember to promote the following: Stay weather aware and away from flooded areas. As the wave moves to the east of the local area Friday afternoon through the evening, rain chances come to an end from west to east. Breezy north winds are forecast to prevail late Friday afternoon through the overnight hours with gusts of 30 to 40 mph. && .LONG TERM... (Saturday through next Thursday) Issued at 114 PM CDT Thu Apr 30 2026 By Saturday morning, dry and cooler weather conditions are in store as a surge of cooler airmass pushes from the north resulting in lows around the mid 40s over the Hill Country to mid 50s across the Coastal Plains. Saturday's highs are forecast to range from the upper 60s to mid 70s. A surface high pressure system over South Central Texas Saturday evening pushes to the east overnight into Sunday and brings back a southerly flow to the local area. With the return flow in place, a warming trend begins on Sunday with forecast highs in the mid to upper 70s to low 80s along the Rio Grande. The warming trend and dry weather conditions continue at least through next Wednesday. && .AVIATION... (18Z TAFS) Issued at 1254 PM CDT Thu Apr 30 2026 With the exception of KAUS where thunderstorms could impact the terminal within the next few hours, drier conditions are now forecast for most of the day and took out the mention of precipitation at all other sites through 00Z. The forecast becomes a bit more messy heading into tonight through Friday as we expect multiple rounds of showers and thunderstorms to impact terminals. MVFR to IFR ceilings will likely linger over the northern half of the area today while some scattering and lifting of ceilings will be seen to the south. Any VFR conditions will be brief as widespread IFR to LIFR conditions develop along with long duration showers and periods of thunderstorms. && .PRELIMINARY POINT TEMPS/POPS...
