KEY MESSAGES

- Warmer and drier weather through Friday.

- Low rain chances return over the weekend and continue into next week.

UPDATE

Issued at 527 PM CDT Wed May 27 2026

Adjusted grids by lowering current temperatures across our eastern zones,have lowered dew points and morning lows area wide as well through tonight. PoPs have been taken out for the rest of the day. Added in patchy fog for areas east of the Escarpment given the ground moisture from the recent rains and light winds.

SHORT TERM

(Tonight through Thursday night) Issued at 1249 PM CDT Wed May 27 2026

The secondary storm complex with developed further south than the main line from yesterday into early this morning is finally east of the area. Mainly dry conditions are now expected for the rest of the afternoon and evening, though an isolated shower or non-severe storm cannot be ruled out along and east of I-35 if the atmosphere has time to destabilize. Our departing shortwave will allow for brief, weak ridging to return over the area through Friday bringing drier and warmer weather back to South Central Texas. Humid conditions will stick around late week as highs climb into the upper 80s and low 90s by Friday bringing heat index values into the mid and upper 90s.

LONG TERM

(Friday through next Wednesday) Issued at 1249 PM CDT Wed May 27 2026

A deep, upper low will be lifting northeast towards the Rockies Friday into Saturday shifting our upper ridging east. Southwesterly flow returns aloft bringing back opportunities for disturbances to propagate towards the area in conjunction with the return of near to above average moisture; hence, the periods of low to medium precipitation chances for the weekend into the middle of next week. Model guidance continues to unorganized in this pattern not giving a good glimpse into the better times for any possible showers and storms during this period. Warm highs and lows continue during this period with clouds expected to develop each night.

AVIATION

(18Z TAFS) Issued at 1249 PM CDT Wed May 27 2026

Some spotty low CIGs, mainly MVFR, will hide under the thick cirrostratus canopy for a couple hours, but we expect most to be east of the I-35 sites for the afternoon. Mostly clear skies should take over for the evening, and with light winds, the conditions should become favorable for patchy fog and low clouds with all the rain that was received. Will keep AUS VFR on CIGs but this could be replaced by patchy fog that could briefly go VLIFR. The return flow winds over SAT/SSF/DRT could support some IFR conditions, but we show MVFR skies there, since DRT got less rain in the area. MVFR cigs could last well into the morning and early afternoon.
