352 FXUS64 KEWX 150009 AFDEWX Area Forecast Discussion National Weather Service Austin/San Antonio TX 709 PM CDT Sat Jun 14 2025 ...New AVIATION... .SHORT TERM... (Tonight through Sunday night) Issued at 153 PM CDT Sat Jun 14 2025 Key Message: - Isolated to scattered convection this afternoon/early evening and again on Sunday. Convection ongoing across the coastal plains and Highway 77 corridor will continue and gradually spread westward. We expect to see new convective development to the west of where storms are ongoing as a westward moving outflow boundary helps to initiate additional showers and storms. This includes the I-35 corridor into portions of the Hill Country. A few of the stronger storms will be capable of producing locally heavy rainfall, gusty outflow winds and frequent lightning strikes. Some minor flooding may also develop especially over the coastal plains of Karnes, DeWitt and Lavaca counties where some notable rainfall totals have occurred as of late. We should see a gradual decrease in the coverage of showers and storm through the early evening hours as daytime heating ends. On Sunday, we expect to see a similar weather pattern develop with convection initially developing over the coastal plains, then gradually spreading westward into the I-35 corridor, Hill Country and possibly as far west as portions of the southern Edwards Plateau. Temperatures on Sunday will range from near 100 degrees along the Rio Grande to the lower 90s in the Hill Country. Some highs may stay down in the lower 90s over the coastal plains if precipitation and cloud cover develop as expected. && .LONG TERM... (Monday through Saturday) Issued at 153 PM CDT Sat Jun 14 2025 Key Messages: - Seasonably hot and humid conditions expected through next week. - Ridging remains west of the area, allowing periodic rain and storm chances to move in behind north to northwesterly flow aloft. Mid-level ridging will remain close enough influence our sensible weather through the start of the upcoming week. Temperatures will warm into the mid to upper 90s outside of the Rio Grande Plains where highs will top out in the 100-105 range through Wednesday. With our recent rains adding copious amounts of moisture to the soil, evapotranspiration will result in sticky/humid conditions this week, particularly in the mornings. Afternoons should see enough mixing out that heat indices remain in check. By mid to late week, a slightly more active pattern looks to return as both GFS/ECMWF operational and ensembles indicate northerly to northeasterly flow aloft bringing the storm track back into South Central Texas. The seabreeze should also be a bit more active by late week as well, resulting in a return to rain and storm chances each day Thursday through Saturday. && .AVIATION... (00Z TAFS) Issued at 659 PM CDT Sat Jun 14 2025 Convection has dissipated early thanks to a formidable convective outflow. A brief stray shower might pop up east of DRT, but no more rain or lightning is expected near the TAF sites. VFR skies should hold up until near midnight when MVFR cigs should return to SAT/SSF. Will follow persistence and show the cigs arriving at AUS a couple hours later and the DRT area close to daybreak. Good mixing on Sunday should have all sites back to VFR by around 18Z. South to SE winds should do their typical veering at night and backing in the afternoon, with afternoon gusts to around 20 knots possible. && .PRELIMINARY POINT TEMPS/POPS...
