Make sure to be prepared for the warmer temperatures if you plan to work or spend time outdoors. - Daily chance for showers and thunderstorms expected next week. && .DISCUSSION... Issued at 1118 PM CDT Thu May 28 2026 Patchy fog is expected to develop over portions of SE Texas early this morning with some dense pockets possible. Onshore winds have also returned, and thus surface moisture should increase across the region. As a result, early morning lows for today will be a tad warmer, in the upper 60s/lower 70s. Amplified ridging is still forecasted to be in place over the Plains/Mississippi River Valley today. While SE Texas will be on the southwestern peripheral of the ridge, it will still feel its influence. Rain chances remain sparse with CAMs keeping convective activity largely east of our CWA this afternoon. Highs will be warm, reaching the upper 80s/lower 90s. Heat indices will also reach the 90s, possibly triple digits in a few spots. With summer heat starting to develop across the area, make sure you're drinking plenty of water and cooling off indoors. Similar weather is anticipated for Saturday as mid/upper level ridging remains over much of the Plains/Mississippi River Valley. Continued onshore flow and moisture advection should result in early morning lows in the 70s across the region. Some weak vorticity impulses could undercut the ridge to bring some weak showers/storms in the afternoon, though rain chances are still anticipated to be low for Saturday. Highs should reach the 80s to lower 90s with heat indices in the 90s to triple digits. Sunday is still poised to be another warm day with sparse rain chances. Heading into next week, several impulses may undercut the mid/upper level ridge. This, along with decreasing subsidence should bring daily chances for showers and storms throughout next week. Highs are forecasted to remain in the 80s/lower 90s with lows in the upper 60s/lower 70s. Heat indices remain generally around the 90s to triple digits, easing down slightly during the later half of the week. 03 && .AVIATION...
