SHORT TERM

(Tonight through Tuesday night) Issued at 1226 PM CDT Mon Mar 30 2026

Weak zonal flow will continue today and Tuesday with temperatures above normal for the final two days of March. Temperatures climb into the 80s today and tomorrow with morning clouds giving way to afternoon sunshine and breezy southerly winds. A notable rise in humidity is expected as gulf moisture and return flow ramps up ahead of an approaching storm system moving into the region on Wednesday.

LONG TERM

(Wednesday through next Monday) Issued at 1226 PM CDT Mon Mar 30 2026

An active weather pattern will get the ball rolling for the month of April as a mid-level trough over the west coast ejects out over the High Plains on late Wednesday/early Thursday. A surface low will strengthen in the lee of the Rockies over southwest Kansas Wednesday night, sending a dryline further east into South Central Texas Wednesday afternoon and evening and weak frontal boundary into the Hill Country Wednesday night. The RRFS and some other experimental CAMs are on board with a line of storms developing and pushing east out of the Edwards Plateau/Hill Country and into I-35 Corridor Wednesday night and early Thursday morning. At this time, severe storms are not anticipated given the timing, but if things speed up, then a conditional threat may develop given modest instability and favorable lapse rates, a strong storm or two would be possible, particularly out west. Storms could redevelop Thursday

After storms exit late Thursday morning or early afternoon, warm and dry weather resumes on Friday. Temperatures quickly rebound into the upper 80s but the warm up is short-lived as an even stronger storm system takes shape for Easter weekend. A powerful upper-level low will take shape over the northern Rockies allowing for a strong trough to dig southward over Texas on Saturday. A cold front associated with this storm system will move through our region bringing the best widespread chance at rain for the region since the 1st week of March. Much cooler air along with lingering showers is expected Sunday with highs in the 60s. Cool air lasts through the end of this forecast period with highs in the 60s next Monday as well.
