FXUS64 KHGX 241806 AFDHGX Area Forecast Discussion National Weather Service Houston/Galveston TX 106 PM CDT Wed Jun 24 2026 ...New DISCUSSION, MARINE... .KEY MESSAGES... - Hot conditions will continue this week, with potential for heat stress issues as heat indices approach 105-107F (41-42C) each day and WBGT risk peaks in the red category. && .DISCUSSION... Issued at 105 PM CDT Wed Jun 24 2026 Not too much to write about, as high pressure and upper ridge settle in across the area. The building ridge will keep dry conditions in place through much of the period, with drier air helping to alleviate the higher heat indices we've experiences the last week or so. That said, heat may still be a factor for those spending a lot of times outdoors or those vulnerable to heat, so caution should be used if spending time outdoors. Otherwise, expect highs to warm into the lower to mid 90s and overnight lows in the lower to mid 70s. Moisture will begin to increase this weekend, as the ridge moves east of the area. Meanwhile, weaknesses in the upper ridge may provide some forcing for convection, if any mesocale features lead to a focus for CI. We'll see an increase in afternoon rain chances, typical of our summertime pattern. && .AVIATION...
