KEY MESSAGES

- Warm and humid Monday.

- Chances for showers and thunderstorms Tuesday through Saturday.

UPDATE

Issued at 656 AM CDT Mon Jun 1 2026

Areas of fog have developed over the eastern half of the CWA this morning. A few spots will drop to 1/4 mile visibility. Generally visibility will be 1-3 miles.

SHORT TERM

(Today through Tuesday) Issued at 1243 AM CDT Mon Jun 1 2026

GOES East water vapor imagery shows lingering convection that sparked off the dryline over West Texas and weak mid-level ridging still in place over south central Texas. This shortwave ridge should start to slide a bit further east on Monday, but convection will remain west of the service area. Temperatures should climb into the upper 80s to lower 90s along with continued stubborn mid-level clouds. Tuesday will start the transition to a more active pattern with continued southerly to southeasterly surface flow sending PWATs up above 1.5 inches. Showers and storms are possible Tuesday afternoon and evening, particularly over the northern half of the area as a weak inverted trough over the northern Gulf moves westward into South Central Texas. Locally heavy rainfall and tropical-like downpours look like the primary hazard, but gusty winds are also a possibility.

LONG TERM

(Tuesday night through Sunday) Issued at 1243 AM CDT Mon Jun 1 2026

Wednesday continues the stretch of active weather with daily rain and storm chances through the end of the week. This time, it'll be more due to the increased southwesterly flow aloft and weak disturbances each day bringing the threat for continued beneficial rainfall. By Thursday-Friday, and upper-level low over the Baja of California will lift north and east, and increase divergence over the region, providing a favorable environment for efficient rain- producing storms. The pattern will be rather favorable for rain, but predicting when individual rounds of rain and storms arrive is an exercise in futility at this distance. While there are signs that mid-level ridging could return by early next week, the active pattern is expected to continue through this forecast package.

AVIATION

(12Z TAFS) Issued at 538 AM CDT Mon Jun 1 2026

MVFR and IFR cigs are likely to continue across the local area terminals through 16Z. Afterward, VFR conditions prevail through late tonight/overnight. Light southerly winds are forecast through the period with gusts of 15 to 20 knots for KDRT this afternoon. MVFR cigs return overnight with patchy to areas of fog developing across the Coastal Plains. Can't rule out for fog to affect some areas along the I-35 corridor during the overnight/Tuesday morning period.
