FXUS64 KHGX 230010 AFDHGX Area Forecast Discussion National Weather Service Houston/Galveston TX 710 PM CDT Mon Jun 22 2026 ...New AVIATION... .KEY MESSAGES... - Hot conditions will continue this week, with potential for heat stress issues as heat indices approach 107F (41-42C) each day. - A high risk of strong rip currents will continue early this week. && .DISCUSSION... Issued at 135 PM CDT Mon Jun 22 2026 Upper ridging will continue to build into the region today, with high pressure at the surface. Despite some cloud cover, the height rises have allowed temps to warm into the lower 90s across most of the area. Fortunately, with the drier air working its way in with the ridge, dewpoints have fallen into the mid 70s. This has tempered the heat indices from rising above 107, however some heat concerns will persist. Dry conditions will prevail through the remainder of the period as the ridge settles in across the area. Several disturbances to our north will spark convection over the Mid West and Central Plains, but the building ridge will provide enough subsidence over the area to keep a dry forecast. The only concern remains the potential for heat related issues, as daytime highs climb into the mid 90s each afternoon and overnight lows fall into the mid to upper 70s. The lower dewpoints will also persist, so we will likely remain below heat advisory criteria. Those most vulnerable may still be susceptible to the heat, so heat safety actions should be in place each day. && .AVIATION...
