Updated at 1223 AM CDT Wed Jul 30 2025 - Daily moderate to major risk of heat-related impacts. - Borderline elevated fire weather this afternoon/evening over the northern Brush Country and Rio Grande Plains. Limited by weak winds. - Low rain chances return Thursday into early next week, mainly over the Victoria Crossroads. && .DISCUSSION... Issued at 1223 AM CDT Wed Jul 30 2025 Clear skies, light winds, and below-normal moisture are associated with a mid-level ridge and surface high currently situated over the region. Allowing for areas to patchy dense fog this morning across the inland Coastal Plains. This pattern will continue through tonight as the center of the high retrogrades westward today allowing an inverted trough to approach the Texas coast from the east and lingering over the region Thursday through Friday. The inverted trough will result in increased moisture through the weekend with PWAT values around 1.75"-2". This moisture, combined with PVA associated with the aforementioned inverted trough, will warrant low rain chances (15-25%) through the weekend. Early next week, a mid-level high begins to move into the region from the west along with a shortwave rounding the periphery of the high allowing for low rain chances to continue through the first half of the week but the best rain chances remain off to the northeast. A minor to moderate risk of heat-related impacts will continue Wednesday, then increase to moderate/major the remainder of the week into the weekend and early next week due to increasing moisture and air temperatures. surface temperatures in the lower 90s will persist along the coast with values around 105 over the Rio Grande Plains. Heat indices will peak around 105-110 degrees the remainder of this week into early next week. && .AVIATION... (06Z TAFS) Issued at 1223 AM CDT Wed Jul 30 2025 VFR conditions are expected to last through the period for the western sites. The conditions at the eastern sites (ALI,CRP,VCT) are expected to deteriorate over the next couple of hours dropping to IFR to LIFR CIGs and VSBYs. This is expected to trend through mid-mornning 14-15Z before burning off allowing conditions to return to VFR through the remainder of the period. Winds are expected to be light through the day today. && .MARINE... Issued at 1223 AM CDT Wed Jul 30 2025 A light to gentle (BF 2-3) variable flow is expected to continue through this evening before becoming a gentle to moderate (BF 3-4) south to southeasterly flow through early next week. There is a very low 10-15% chance of showers and thunderstorms Thursday into early next week mainly over the offshore waters. && .FIRE WEATHER... Issued at 1223 AM CDT Wed Jul 30 2025 Very dry air with minimum relative humidity around 20% along with Energy Release Component (ERC) values above the 75th percentile, and occasional wind gusts approaching 20 mph will once again lead to a greater risk for elevated fire weather this afternoon over the northern Brush Country and Rio Grande Plains. Otherwise, sustained winds are expected to remain less than 15 mph, thus limiting the fire weather threat. && .PRELIMINARY POINT TEMPS/POPS...
