Issued at 127pm CDT Tuesday April 14 2026 High pressure over the Gulf will maintain warm, dry, and breezy weather through the remainder of this week. Above average temperatures with highs around 90 (80s near the coast) and morning lows in the low 70s will continue through Saturday. Breezy southeasterly winds will continue, with gusts of 30-35 mph possible each afternoon, with the breeziest afternoon being Friday.

Ensemble PWAT (Precipitable Water) values are forecasted to be greater than the 90th percentile of climatological normals (1.7- 1.9").
