KEY MESSAGES

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

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

SHORT TERM

(Tonight through Saturday night) Issued at 102 PM CDT Fri May 29 2026

Mid-level ridging over Central Texas gradually shifts east through this evening as a trough over the western US pivots towards the Northern Rockies. This pattern brings back west to southwesterly flow over our area by late this afternoon and continues through the weekend. Weak embedded disturbances within the mid-level flow in addition to the dry line in West Texas may trigger some isolated to widely scattered thunderstorms this afternoon and evening. Storms would initiate west of the area, but could approach or move into the southern Edwards Plateau before dissipating with the loss of daytime heating. This same pattern of storms firing off in West Texas or Mexico and potentially moving into our far western areas continues Saturday and again Sunday with little change in the overall pattern.

For the rest of the region, dry weather is anticipated through the weekend with seasonable temperatures ranging from the upper 80s to mid 90s. South to southeasterly flow will generally be light though the weekend with mostly clear skies today becoming partly cloudy tomorrow due to increasing mid-level moisture.

LONG TERM

(Sunday through next Friday) Issued at 102 PM CDT Fri May 29 2026

The Sunday forecast remains similar to earlier in the weekend, then above average moisture returns to the area Monday and continues through the rest of next week. Forcing will be weak much of next week with precipitation chances mainly driven by diurnal heating or some seabreeze activity accompanied by mid-level disturbances. Guidance still does seem to favor the middle to late week timeframe for the better rain chances with highest chances each afternoon and evening.

With increased moisture we will get back into a pattern of clouds developing overnight bringing warm lows in the 70s for much of the area with highs in the upper 80s and 90s. Towards the middle or end of the week clouds may stick around during the day with the forecast trending a few degrees cooler with highs mainly in the 80s.

AVIATION

(00Z TAFS) Issued at 621 PM CDT Fri May 29 2026

Generally light south to southeast winds continue across the region with VFR conditions, followed by another cycle of MVFR to IFR CIGs redeveloping over most of the region with highest confidence at KSAT/KSSF before lifting and clearing for all areas in the afternoon. Low potential exists for isolated SHRA/TSRA near KDRT after 21Z.
