578 FXUS64 KEWX 060606 AFDEWX Area Forecast Discussion National Weather Service Austin/San Antonio TX 106 AM CDT Sun Jul 6 2025 ...New SHORT TERM, LONG TERM, AVIATION... .KEY MESSAGES... - Threat of Flash Flooding from slow moving and repeat heavy rains continues through this morning. The Flood Watch for the Hill Country and I-35 corridor through 1 PM CDT today. - Rain chances continue on Monday and Tuesday. - Eventually trending seasonably drier and warmer this coming week. && .SHORT TERM... (Today through Monday) Issued at 101 AM CDT Sun Jul 6 2025 A mid level MCV and unseasonably moist airmass with PWs of 1.7 to 2.4 inches remain in place over our area. This feature and moist airmass lingers over our area today. Forcing by this feature along with heating will generate showers and thunderstorms with multiple models favoring going into this morning. Storm motion vectors favor slow moving and repeat activity to enhance the efficient warm rain processes. Locally heavy rains with amounts of 2 to 4 inches are expected with isolated amounts up to 10 inches possible. These amounts will aggravate ongoing flooding and likely create new flooding as soils are very saturated making runoff more rapid. The heaviest rains are favored over the Hill Country to along the I-35 corridor. We previously extended the Flood Watch through 1 PM CDT for those areas. The MCV weakens some by Monday with only a slight decrease in moisture/PWs. Showers and thunderstorms may be less focused and have only slight chances on Monday. A few hi-res models show another round of heavy rains late tonight into Monday morning indicating a potential for another Flood Watch. The clouds and rain areas keep daytime temperatures below to well below July averages. && .LONG TERM... (Monday night through Saturday) Issued at 101 AM CDT Sun Jul 6 2025 The mid level feature gets replaced by an inverted trough moving onshore the Texas coast on Tuesday keeping moisture levels elevated. The blended guidance has caught on to the trends of the last several model runs and indicates low chances of showers and thunderstorms Tuesday afternoon and will follow suit. Models/ensembles now show the Subtropical Ridge not fully building over our area with some keeping a weakness in the Ridge overhead. All show a drier airmass spreading over our area keeping rain chances out of the forecast for the remainder of the week. However, with moisture levels maintaining seasonal PWs, cannot rule out shower or two each day mainly near the Coastal Plains with the seabreeze. Trends are for temperatures to reach near mid July averages. && .AVIATION... (06Z TAFS) Issued at 101 AM CDT Sun Jul 6 2025 MVFR ceilings developing overnight along the I-35 corridor with MVFR to IFR ceilings in the Hill Country. Ceilings are forecast to become VFR again 16Z-18Z. A mid level disturbance will remain near the region through Sunday. Widely scattered SHRA development is forecast near this feature overnight and Sunday morning across the I-35 corridor from SAT through AUS and especially northwest into portions of the Hill Country. An uptick in convective coverage and intensity is possible Sunday afternoon through the Hill Country, with some embedded TSRA. && .PRELIMINARY POINT TEMPS/POPS...
