.SHORT TERM... (Today through Friday night) Issued at 257am CDT Wednesday May 14 2025

A steady rise in temperatures can be expected starting today and over the remainder of the short term period. Modest southerly flow is driving Gulf moisture back into the region making for oppressive overnight mugginess and very hot-feeling daytime temps. High temps should top out in the upper 80s to lower 90s, but heat indices in the 90s to near 100 are expected today, Thursday and Friday.

High pressure ridging into the region will keep the forecast hot and without precipitation chances. A tightening pressure gradient between high to the southeast and shortwave moving through Texas will result in breezy southerly winds today. Speeds should remain below Wind Advisory conditions, so the product was not issued with this forecast package.

Long Term
(Saturday through Wednesday) Issued at 257am CDT Wednesday May 14 2025

No major departures from the previous forecast thinking. High pressure riding remains in majority control over the longterm period. While a series of trough. move across the central US, high pressure blocks any appreciable lift from entering the CWA. There could be some periods of cloudy skies, but ultimately no rain chances are expected.

Very hot weather is the greater concern as the oppressive heat wave continues for several more days. Temperatures in the upper 80s to lower 90s will prevail each day. Elevated humidity will drive daily heat indices into the upper 90s to lower 100s each day as well. While we won't be hitting traditional heat advisory criteria, a Heat Risk of moderate to major impact can be expected due to longevity of heat, departure from normal this time of year and humidity.

Marine
Issued at 257am CDT Wednesday May 14 2025

A weak shortwave moving near the region will tighten the gradient against high pressure in the north Gulf, resulting in breezy onshore flow around 20 knots gusting to 30 knots through this afternoon. Another round of elevated winds are expected during the day Thursday. Long southerly fetch in the west Gulf will keep elevated seas in the forecast through Thursday as well. Thus, Small Craft Advisory conditions are expected to continue. Otherwise, ridging remains in control and no rain is expected through the forecast period.
