Area Forecast Discussion National Weather Service Austin/San Antonio TX 836 AM CDT Wed May 6 2026 ...New UPDATE... .KEY MESSAGES... - Low to medium (20-50%) rain/storm chances return for the middle to end of the week. - A cold front will move through late Wednesday, with cooler temperatures expected Thursday. - Temperatures rebound quickly this weekend along with low rain chances and highs in the 80s to lower 90s. && .UPDATE... Issued at 834 AM CDT Wed May 6 2026 A Severe Thunderstorm Watch has been issued across much of the Hill Country into portions of the I-35 corridor that is north of San Antonio until 1 PM. Isolated severe storms will be capable of large hail and strong winds. Adjusted the PoPs this morning and into this afternoon given current trends and latest short term guidance members. && .SHORT TERM... (Today through Thursday) Issued at 1242 AM CDT Wed May 6 2026 Moisture continues to pool over South Central Texas this evening ahead of an approaching cold front which is progged to arrive Wednesday afternoon. With moderate instability and a retreating dryline over the western CWA this evening, a few storms could develop over the northern Rio Grande Plains and Southern Edwards Plateau. They would primarily pose a large hail risk IF a storm can form. Otherwise, increasing clouds are expected overnight as ample moisture continues streaming northward. Overnight into Wednesday morning, wouldn't be surprised to see some drizzle or mist as low clouds and stagnant air sets up ahead of the approaching front. Most locations should still climb into the 80s Wednesday before the front passes through in the late afternoon and evening hours. A dryline will progress eastward during the day Wednesday, but capping is expected to remain rather strong, so the threat for storms is low before the front arrives. A few strong to severe storms with all hazards possible could develop along the front, with the highest severe threat over Williamson, Lee, portions of Fayette, and northern Bastrop. We'll carry a 20-30% chance for storms Wednesday afternoon/evening, generally along and east of the I-35 Corridor, but the risk is highly conditional. Most areas won't see any rain at all Wednesday. Additional showers and storms should develop after midnight Wednesday night into early Thursday morning as cooler air filters into the region. This will likely be more of isentropic type showers and storms but not as widespread as some of our more recent rain events. && .LONG TERM... (Thursday night through Tuesday) Issued at 1242 AM CDT Wed May 6 2026 Thursday will be the coolest day of the week as cooler air behind the front filters into South Central Texas. Highs should only climb into the 60s and 70s but the cooldown will be short-lived. In any matter, we'll take it, especially since cold fronts of this magnitude are less common in the month of May. Friday and beyond is when things start to get a bit more interesting as a trough and associated closed low move eastward into northern Mexico and southwest Texas this weekend. An active pattern continue with this setup, with scattered showers and storms expected to develop both Saturday and Sunday. Beyond that, models begin to diverge on the pattern into next week. It looks like things will remain active, but in terms of any specific day having better odds at rain, it's difficult to say at this distance. && .AVIATION... (12Z TAFS) Issued at 559 AM CDT Wed May 6 2026 A couple of severe storms formed just north of Val Verde County, and it appears the rain chances are going to avoid the TAF locations for the most part. In the early afternoon, there could be a need to add a prob30 for AUS, but will leave that for the day crew to monitor. Other light sprinkles and drizzle should have no impacts on VSBY, but that might be enough to pull a CIG height down below 1000 ft this morning. MOS guidances are a bit torn on what the front will do with the NAM noticeably stronger with post-frontal winds. With low confidence on which route to take will side with the slightly stronger winds and less lowering of CIGs as the previous couple fronts we got was also a bit stronger than advertised. && .PRELIMINARY POINT TEMPS/POPS...
