Area Forecast Discussion National Weather Service Austin/San Antonio TX 159 PM CDT Tue Jul 9 2024 ...New SHORT TERM, LONG TERM... .SHORT TERM... (Tonight through Wednesday night) Issued at 159 PM CDT Tue Jul 9 2024 Widespread showers and thunderstorms with locally heavy rainfall rates of 1-2" per hour or sliding southward through the Rio Grande Plains and Southern Edwards Plateau early this afternoon. A 500mb shortwave will work through a weakness in the mid level wind fields in the wake of Beryl, allowing this convection to continue moving through the region this afternoon and evening. This activity should work through the San Antonio metro and down the I-37 corridor into the southwestern CWA this evening. Some minor flooding will be possible with this activity, as has already been seen over parts of Edwards, Kerr, and Bandera counties. On Wednesday, South Central Texas will be within a bit of a "dead zone" or a col. With remnant boundaries from storms left behind from Tuesday's convection, showers and storms are expected to develop again, but this time, a bit further south, generally south of San Antonio metro. However, some of the latest hi res guidance does indicate the chance for some convection to fire as far north as Blanco and Hays counties. Have adjusted PoPs northward to account for some of this uncertainty on Wednesday afternoon. Continued active weather is expected in the long term period. && .LONG TERM... (Thursday through Tuesday) Issued at 159 PM CDT Tue Jul 9 2024 An inverted trough moves into coastal areas of Mexico on Thursday while South-Central Texas continues to sit within a col (or saddle point) region in the light mid-level flow. Highest moisture levels during Thursday focus over South Texas and provides a slight chance for convection across our southern most counties. Elsewhere, rain chances remain minimal Thursday. As the inverted trough advances farther inland across interior sections of Mexico from Friday into Saturday, this helps to turn the flow aloft more southerly across the region and advect an axis of higher PWAT values across the region with values ranging between 1.6 and 2 inches. This promote rain chances in the isolated to scattered category both Friday and Saturday. This activity will peak in the afternoons with daytime heating before diminishing into the night. The rain chances lower into early next week as the inverted trough moves farther away and the 500 mb heights gradually rise from late Saturday into Sunday. However, some isolated convection could develop over the coastal plains with the sea breeze. Another upper level weakness could develop over our western areas into early next week but there are some model disagreement on this feature. The temperatures will run near to slightly above average through the period. However, heat index values may become a concern towards early next week. && .AVIATION... (18Z TAFS) Issued at 1217 PM CDT Tue Jul 9 2024 A bit of a tricky forecast this afternoon, but confidence is increasing in the threat for -TSRA over SAT, SSF, and DRT this afternoon through as late as the evening hours. Winds will remain light and variable outside of any unforeseen gusts possible with outflow boundaries from thunderstorms in the area. Ceilings should remain VFR but could dip to MVFR in the heaviest of storms. With higher confidence at DRT, have gone with a TEMPO -TSRA group, and just a PROB30 group at SAT and SSF. && .PRELIMINARY POINT TEMPS/POPS...
