DISCUSSION

Issued at 1116 PM CDT Wed May 27 2026

Patches to areas of fog will be possible early in the morning, especially in fog-prone areas that received heavier rains, with model guidance showing visibility quickly deteriorating in the pre-dawn hours leading up to sunrise. Dense pockets will be possible during this early morning period as well. Early morning lows will range from the 60s to lower 70s. The shortwave trough currently overtop of SE Texas will be slowly filling to the east- northeast throughout today. As a result, rain chances should be decreasing, though some isolated/scattered lingering showers cannot be ruled out, mostly east of I-45. Otherwise it'll be a very warm day with highs in the 80s, with a few spots potentially hitting the 90 degree mark.

Onshore winds return overnight, bringing moisture return into the early morning hours of Friday. Morning lows for Friday will be slightly warmer as a result, mostly in the 70s with isolated upper 60s in a few spots. Amplified ridging will be in place over the Plains/Mississippi River Valley during the day, with SE Texas placed along the ridge's southwestern peripheral. Rain chances will be sparse, though some isolated showers could occur around peak heating. Highs will be in the 80s to lower 90s.

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.

Rain chances increase into Sunday as several impulse undercut the mid/upper level ridge. Decreasing subsidence should bring daily chances for showers and storms through at least mid week. Highs are forecasted to remain in the 80s/lower 90s with lows in the upper 60s/lower 70s.
