DISCUSSION

Issued at 1100 AM CDT Fri May 29 2026

Benign conditions are expected to persist into the end of the weekend as the mid to upper level ridge over East TX and LA remains as the dominant feature. Southerly flow will continue to feed in warm moisture air from the Gulf, thus, warm conditions are expected with highs in the upper 80s to lower 90s for much of Southeast TX today into early next week. Today's heat indices are expected to peak in the upper 90s with isolated spots possibly reaching the lower 100s. But during the weekend, we could see more areas reaching the lower 100s, in particular on Sunday and Monday as PWs increase to 1.6-2.0 inches. Make sure to be prepared for the heat if you plan to work or spend time outdoors through early next week. Drink plenty of water, take several breaks from the heat/sun, and wear appropriate clothing. The night's will also be rather warm with lows going from the lower 70s tonight, rising into the mid to upper 70s for much of Southeast TX by Sunday night. The lows along the coasts are expected to be in the upper 70s to lower 80s.

We could have slight chances of showers over the Gulf waters Sunday night and early Monday, which can move into our coastal locations from time to time. Rain chances would then increase Monday afternoon as moisture further increases over the area and the ridge weakens while weak disturbances embedded in the western periphery of the ridge move aloft. Daily chances for showers and thunderstorms will continue for much of the work week as upper level disturbances continue move through the region and southerly flow supplies warm moisture air into Southeast TX. The best opportunities for development of thunderstorms look to be during the afternoon and evening hours when diurnal heating and instability are at its best. The forecast still shows at our high temperatures falling back into the upper 80s by mid-week.
