FXUS64 KEWX 072332 AFDEWX Area Forecast Discussion National Weather Service Austin/San Antonio TX 632 PM CDT Tue Jul 7 2026 ...New AVIATION... .KEY MESSAGES... Updated at 622 PM CDT Tue Jul 7 2026 - Low chance for showers and storms this afternoon, but locally heavy rainfall is possible with any storms that form. - Warm temperatures persist through the week with most areas remaining dry Wednesday and Thursday. - Increased moisture brings scattered showers and thunderstorms this weekend with perhaps a slight drop in temperatures. && .SHORT TERM... (Tonight through Wednesday night) Issued at 124 PM CDT Tue Jul 7 2026 Satellite imagery and regional radar show a remnant MCV centered over northern Maverick and southern Val Verde county. This disturbance was responsible for several inches of rainfall for the Edwards Plateau and portions of the Rio Grande Plains yesterday. Additional showers and storms are expected to form in the Rio Grande Plains this afternoon and evening, with locally heavy downpours and minor flooding being the primary concern. Elsewhere, a weak mid- level trough sagging south over the ArkLaTex will result in shower and storm development over the eastern part of the state. Here locally, remnant moisture and strong daytime heating should allow some activity to develop this afternoon and evening over areas generally along and east of US 281, but a stray shower or storm cannot be ruled out over the Edwards Plateau again. Any activity will produce locally heavy rainfall capable of minor flooding given slow storm motions. Storms that do form should fizzle out quickly after 03Z. Wednesday will be a hot and dry day with the aforementioned MCV and mid-level trough out of the picture and shortwave ridging building over south central Texas. Temperatures will start out in the upper 60s to middle 70s, warming into the mid to upper 90s by the afternoon along with mostly sunny skies. && .LONG TERM... (Thursday through next Tuesday) Issued at 124 PM CDT Tue Jul 7 2026 Thursday will be yet another dry day with temperatures climbing into the mid to upper 90s again. Heat indices should remain tame given adequate afternoon mixing lowering dewpoints by later in the day. Friday starts the transition to increasing moisture as a disturbance/inverted trough over the southwestern Gulf lifts northward and brings a good chance for showers and storms back into the picture for the weekend. PWATs will surge into the 2-2.25" range Saturday and Sunday, which would result in heavy rainfall rates and tropical-like downpours in any showers or storms that form. Beyond Sunday, a more active pattern may develop with broadscale troughing noted over the western CONUS and southern Plains states while the subtropical high moves over the northern Plains. && .AVIATION... (00Z TAFS) Issued at 622 PM CDT Tue Jul 7 2026 VFR conditions remain across the region, isolated SHRA/TSRA continue to remain possible near KAUS this evening as multiple outflow boundaries approach the terminal. This boundary has already moved through KSAT sparking off some -SHRA/-TSRA as noted in this forecast. Otherwise, expect VFR cigs this evening and overnight with brief possible MVFR cigs around daybreak for all I-35 terminals. Winds should relax overnight before increasing again by late morning into the afternoon and remaining southerly and generally under 10 knots. For KDRT VFR cigs expected throughout the period with easterly winds of 5 to 10 knots overnight turning SE and increasing to around 10 knots after sunrise. && .PRELIMINARY POINT TEMPS/POPS...
