855 FXUS64 KEWX 160658 AFDEWX Area Forecast Discussion National Weather Service Austin/San Antonio TX 158 AM CDT Mon Jun 16 2025 ...New SHORT TERM, LONG TERM... .SHORT TERM... (Today through Tuesday) Issued at 155 AM CDT Mon Jun 16 2025 Key Messages: - Low chances of rain east today - Seasonable temperatures with elevated heat index values A few very light showers are noted dropping south. However, they should dissipate by sunrise. Subtropical ridging builds over our area in the short term. Heating and the seabreeze should generate isolated showers and thunderstorms near the Coastal Plains today where an MCV is noted. A shower or thunderstorm or two may be able to make it to the I-35 corridor by evening. Cannot rule out gusty winds and heavy downpours. Otherwise, strengthening subsidence and drying with the ridge will overcome any forcing to keep rain chances out of the forecast. However, cannot rule out a shower or two on Tuesday. Evapotranspiration from moist soils and vegetation due to recent rains maintains near average temperatures and mildly elevated afternoon heat index values. && .LONG TERM... (Tuesday night through Sunday) Issued at 155 AM CDT Mon Jun 16 2025 Key Messages: - Dry weather with near normal temperatures until mid-week. - Thunderstorm chances will return for the latter part of the week. A mid to upper level ridge will over west TX. Subsident flow around this ridge will suppress most convection Wednesday. Wednesday high temperatures will be close to normal. However, southeasterly low level flow will keep dewpoints in the upper 60s and lower 70s making heat indices 100 to 105. Thursday an inverted trough will move into TX from the Gulf weakening the upper ridge. This should allow afternoon convection to move in from the coast across the Coastal Plains and into the Hill Country. This unsettled pattern will continue each afternoon through Sunday. At this time any convection looks ordinary with only isolated moderate rainfall, but given the time of year an occasional strong storm isn`t out of the question. && .AVIATION... (06Z TAFS) Issued at 1234 AM CDT Mon Jun 16 2025 The SHRA/TSRA Sunday afternoon into evening have disrupted the lower level flow while fairly thick clouds at FL200 linger. As a result, the onset of MVFR CIGs may be delayed. Currently have 08Z for the I-35 sites and 10Z for KDRT. In addition, due to the rainfall, a period of IFR, possibly LIFR CIGs is possible early in the morning. Have introduced TEMPOs for IFR 10Z-14Z. Clouds should mix to VFR by midday on Monday. ISOLD SHRA/TSRA are expected near the Coastal Plains on Monday with a slight potential of moving to the I-35 corridor by late afternoon. Have left mention out as PROBs are too low. VRBL winds resume from the S to SE overnight. && .PRELIMINARY POINT TEMPS/POPS...
