Updated at 629 PM CDT Fri Aug 8 2025 - Generally low to medium 20-45% chances of showers and thunderstorms over the weekend and into early next week. - Generally minor to moderate risk of heat related impacts across most of South Texas. At times, a brief major risk can be expected across portions of the Brush Country, through the period. - Elevated fire weather conditions across the southwestern portions of Webb County through the weekend and into next week. && .DISCUSSION... Issued at 1233 PM CDT Fri Aug 8 2025 A mid and upper level high pressure system remains dominate across S TX, keeping rain chances low (10-20) tonight through Saturday, as well as hot with afternoon heat indices generally ranging from 100- 109. A few areas could briefly reach around 110 as the sea breeze moves inland each afternoon, but conditions should remain below Heat Advisory levels due to it being localized and brief. Generally there is minor to moderate risk of heat related impacts each day with a few locations across the Brush Country briefly reaching major risk through the period. The high will shift northwest Sunday as an inverted trough approaches S TX from the gulf. This will bring slightly deeper moisture along with upper support and will combine with the sea breeze to produce more areal coverage of showers and thunderstorms. Rain chances will be low to medium (20-40%)by Sunday and continues through Tuesday. Ridge builds across the area as the trough exits to the west. Thus, decreasing rain chances to 10-20% by the middle of next week. Elevated fire weather conditions may exist across southwestern portions of Webb County due to minimum RH values forecast to be 25- 30 percent and above normal Energy Release Component values. However, winds are expected to remain below thresholds. && .AVIATION...
