610 FXUS64 KEWX 142044 AFDEWX Area Forecast Discussion National Weather Service Austin/San Antonio TX 344 PM CDT Mon Jul 14 2025 .KEY MESSAGES... - Flood Watch now in effect until 7 AM Tuesday for the Hill Country, Southern Edwards Plateau, and I-35 Corridor. - Additional rainfall of 1-3 inches with isolated higher totals up to 6 inches possible. Additional river rises are possible. - Drier regime mid to late week with slightly higher temperatures. && .SHORT TERM /THROUGH TUESDAY NIGHT/... Issued at 250 PM CDT Mon Jul 14 2025 An MCV continues to spin near the Mexican border this afternoon. There are isolated showers and thunderstorms from the Rio Grande to Hwy 281. Convection is generally producing moderate rain now. PW in the airmass is still abnormally high, and any stronger updrafts could produce locally heavy rain. These systems tend to be more active overnight when the low level jet strengthens. We are seeing the diurnal reduction which should continue after sunset. This MCV will still be in the region tonight and interact with our very moist airmass. Showers and thunderstorms will continue tonight and Tuesday with locally heavy rain possible. Additional rainfall of 1-3 inches with isolated totals up to 6 inches is possible. We are going to extend the Flood Watch until Tuesday morning and expand it to include all of the I-35 Corridor. Models move the MCV away from our CWA Tuesday evening bringing an end to rain chances. && .LONG TERM /WEDNESDAY THROUGH MONDAY/... Issued at 250 PM CDT Mon Jul 14 2025 A drier weather pattern will move in mid to late next week with the upper ridge nudging westward into the area from the Gulf. Most areas should remain rain free outside of perhaps a stray to isolated shower or storm with the onshore flow and/or sea breeze. Best chance of this would be Friday in the coastal plains. With the decrease in overall cloud cover and slightly stronger 500 mb heights, expect for a slight uptick in the daytime highs through the second half of the week and into the weekend. Right now, rain chances remain out of the forecast, but we`ll also monitor for the possible development of a tropical disturbance or inverted trough following behind in the wake of the upper level ridging that nudges to our area. This feature may slowly advance westward along/parallel to the northern Gulf coast towards and through the weekend. We continue to monitor to see if this feature gains additional model support within the coming forecast cycles. && .AVIATION /21Z MONDAY THROUGH SATURDAY/... (18Z TAFS) Issued at 1239 PM CDT Mon Jul 14 2025 The main concern through the forecast period is the current MCV making its way across South-Central Texas, especially across the Edwards Plateau and the Hill Country. Currently the MCV has shown signs of weakening and likely not making its way to the I-35 TAF terminals. The greatest probability for flight impacts continues to be for KDRT. There are chances that some redevelopment could occur across the I-35 terminals (KAUS, KSAT, and KSSF) later today, primarily during the afternoon. Confidence on placement and timing, however, is low. Nonetheless have added PROB30s to account for this possibility with VCSHs added for this evening into the overnight hours for all TAF sites. MVFR and possibly IFR flight conditions make a return overnight into late Tuesday morning with VFR conditions returning Tuesday afternoon. && .PRELIMINARY POINT TEMPS/POPS...
