Heat Advisories are likely at times next week. - Later in the week, upper ridging begins to lose its control overhead, allowing temps to moderate slightly and rain chances to return to the forecast && .DISCUSSION... (This evening through next Saturday) Issued at 1217 PM CDT Sun Jul 26 2026 Hot weather will continue to be the main concern across the region. Aloft, ridging is centered over the Four Corners region and extends to the Gulf Coast. This is a fairly strong ridge for this July, with 500 mb heights over the CWA above the climatological 90th percentile. Persistent sinking air associated with this ridge will keep our skies clear and rain chances below 10%. At the surface, high pressure is located in the eastern Gulf, creating continuous but weak onshore flow. Dew points will slowly increase, then plateau into the mid-70s inland and the upper 70s along the coast. With the clear skies daytime heating will help mix down some of the dry air limiting dew points. Temperatures will also steadily increase, with highs in the upper 90s and close to triple digits for northern parts of the CWA. Heat index values will approach the +108 criteria for a Heat Advisory each day during the work week, with the hottest days of the week looking like Tuesday and Wednesday. Even without heat advisories, make sure to stay hydrated and take plenty of breaks from the heat. This pattern will remain stagnant for the next several days with little change to our synoptic setup. We will start to see the ridge begin to weaken and rebuild in the desert southwest. This will allow for troughs to rotate around the ridge increasing our rain chances for the end of the week. With the increase in rains temperatures will decrease slightly back down into the mid 90s. && .AVIATION... (00Z TAFS) Issued at 619 PM CDT Sun Jul 26 2026 A few clouds near 5000ft will continue to stream across the region as we head towards sunset, giving way to mostly clear skies overnight. Light to moderate SW winds will become light to near calm overnight, which may allow for some patchy fog to develop at AEX. Otherwise, VFR conditions prevail. && .MARINE... Issued at 1217 PM CDT Sun Jul 26 2026 Light onshore winds and calm seas will continue for the next five days. Rain chances will return on Thursday. && .FIRE WEATHER... Issued at 1217 PM CDT Sun Jul 26 2026 Hot and dry weather will continue well into the work week. Rain chances will be near zero until Thursday. MinRH will be between 40 and 60 percent through next Friday with RH recovery around 90%. && .LCH WATCHES/WARNINGS/ADVISORIES... LA...None. TX...None.
