(This evening through next Wednesday) Issued at 109pm CDT Thu July 16 2026

Other than a few widely isolated showers and thunderstorms, relatively benign conditions are expected through the rest of the week. High pressure will continue building into the region through the end of the week, further lowering precipitation chances. However, per the typical summer pattern in our part of the world, when Probability of Precipitation drop, temperatures do not. A stray storm or two cannot be ruled out, but any rainfall will be negligible.

Both minimum and maximum temperatures will be on the rise as a warming trend begins this weekend. On average, temperatures will run around 3 to 8 degrees above climatological normals, with highs in the upper 90s to lower 100s. This will yield apparent temperatures between 102 and 113. As a result, heat related headlines will likely be needed next week.

Marine
Issued at 109pm CDT Thu July 16 2026

Light southerly flow and low seas are expected to continue through the forecast period with weak surface high pressure centered over the northeastern Gulf. Mainly dry conditions are expected to prevail as high pressure builds overhead. Winds and seas will be locally higher near thunderstorms.

Fire Weather
Issued at 109pm CDT Thu July 16 2026

Light south to southwest winds will prevail through the week and weekend, keeping dewpoints in the 70s and minimum RH values in the 50 to 65 percent range. Ridging will build across the northern Gulf today through early next week, dropping precipitation chances to near zero. While this drier airmass will lower afternoon RH values into the 40 to 50 percent range early next week, no significant fire weather concerns are expected.
