Updated at 106 PM CDT Tue Aug 19 2025 - There's a Marginal risk for excessive rainfall today and Thursday - Medium to High rain chances persisting through this weekend - Highs will be below 100 beginning later this week lasting through the weekend && .DISCUSSION... Issued at 106 PM CDT Tue Aug 19 2025 The Weather Prediction Center (WPC) has issued a Marginal Risk for Excessive rainfall across much of South Texas for Today and Thursday, that may result in minor flash-flooding of low lying/poor drainage areas. Expected rainfall totals will likely be up to 1.25" through the week with some isolated higher amounts possible. The overall synoptic pattern this week will remain largely unchanged with a pretty stout high pressure anchored over the Four Corners region. Several rounds of PVA from a low pressure system moving across southwestern Canada will round the periphery of this high, moving across our region from the northeast through early next week. This will result in daily medium to high chances (generally ranging from 45-70%) for showers/thunderstorms across much of the region in response to the aforementioned disturbances. This weekend, low to moderate rain chances (30-45%) followed by lower chances early next week. Triple digit temperatures will trend down the remainder of the week, dropping below 100 degrees by this weekend. Followed by a slight warm-up early next week as we slowly dry out. Accompanied by heat indices ranging from around 105-110 degrees each day. Overnight lows will be in the mid-70s. && .AVIATION... (18Z TAFS) Issued at 106 PM CDT Tue Aug 19 2025 VFR conditions may become MVFR as showers/thunderstorms move westward across eastern portions of South Texas this afternoon. Accompanied with periods of reduced VSBYs and gusty winds. Not expecting any fog tonight and light and variable winds expected. Lower chances for showers/thunderstorms possible again tomorrow so have included PROB30s in TAFs for now. && .MARINE... Issued at 106 PM CDT Tue Aug 19 2025 A light to gentle breeze (BF 2-3) is expected to prevail this week. Rain chances return today with a medium to high chance (40-75%) today then a more moderate (50-60%) chance for most afternoons through the end of the week, followed by low to moderate chances early next week. && .PRELIMINARY POINT TEMPS/POPS...
