FXUS64 KHGX 242342 AFDHGX Area Forecast Discussion National Weather Service Houston/Galveston TX 642 PM CDT Fri Jul 24 2026 ...New AVIATION... .KEY MESSAGES... - Scorching hot weather, especially Sunday throughout the upcoming work week. Heat Advisories Likely. - Highs in the 90s/triple digits and heat index values of 104-112. && .DISCUSSION... Issued at 1151 AM CDT Fri Jul 24 2026 After a prolonged period of active weather, Southeast Texas is slated to finally have a fair stretch of calmer weather as a 592-600 dam ridge settles in over the Four Corners/Southern Plains region. Isolated showers (maybe a storm or two at most), will still be possible this afternoon, decreasing and becoming more sparse in nature on Saturday and onwards. Nature's blowtorch kicks into full force from Sunday throughout the upcoming work week as 850mb temperatures climb to around 19-25C. This should result in high temperatures in the 90s to triple digits, with the warmest conditions currently anticipated around Thursday. Daily heat index values could reach 104-112 during the afternoon hours (higher in locally warm spots like asphalt/synthetic turf/etc). Overnight lows will not offer much relief with early morning temperatures in the mid 70s/lower 80s. Heat stress on the human body (based on WBGT) will peak at Extreme levels each afternoon for many spots. Heat advisories are likely to be needed for at least some duration during this period, thus heat safety should be practiced closely. 03 && .AVIATION...
