KEY MESSAGES

- Fair with warm and mostly rain free conditions during the weekend

- Rain and storm chances returning next week, peaks mid to late week

SHORT TERM

(Today through Saturday) Issued at 1234 AM CDT Fri May 29 2026

Mid-level ridging will be in place heading into today but does nudge eastward slightly by the weekend. It shifts east just enough to allow for some modest west-southwesterly flow to be in place aloft across the area. Within this west-southwest flow could be a few weak embedded pieces of mid-level wind energy. These weak perturbations combined with a West Texas dryline helps initiate isolated to widely scattered storms this afternoon and for each afternoon this weekend in West Texas and across the higher terrain of Mexico. It will be possible for activity approaching or during each evening to approach and/or briefly enter portions of the Southern Edwards Plateau before dissipating with loss of daytime heating and increasing convective inhibition. Elsewhere, the vast majority of our region, remains rain free with typical early Summer warmth. Highs will generally range from the upper 80s into the low to mid 90s while overnight lows generally range from the upper 60s into the low to mid 70s. A partly to mostly clear sky continues under a light southerly flow. Morning patchy fog is possible once again this morning but the signal for fog becomes weaker as we go through the weekend.

LONG TERM

(Saturday night through Thursday) Issued at 1234 AM CDT Fri May 29 2026

(Monday through Thursday period) Moisture levels increase across the region heading into Monday with precipitable water values rising towards the 90th percentile range for this time of year with the low- level south- southeasterly flow increasing slightly compared to the weekend. It would be enough to re-introduce some low end rain and storm chances across much of the region. The high moisture levels persist or even climb through mid to late week as the region looks to remain in-between a possible cutoff low off around the Baja California peninsula of Mexico and broad troughiness across the central-western Gulf. This will result in medium (30-50%) rain and storm chances from Tuesday into Friday but no individual day currently looks any more favored than the rest. We'll fine tune these details as we get closer in time. For temperatures, expect near or slightly above average conditions to continue with higher humidity levels and greater cloud cover given the increase in moisture.

AVIATION

(12Z TAFS) Issued at 531 AM CDT Fri May 29 2026
