New SHORT TERM, LONG TERM
KEY MESSAGES
- Dry weather along with above normal temperatures continue through the weekend and into early next week.
- Elevated heat index values later in the week, especially along and east of I-35 and across most of the Rio Grande plains.
SHORT TERM
(Tonight through Wednesday night)
Issued at 1257 PM CDT Tue Jun 23 2026
The subtropical ridge is back over Texas. The low level flow continues to be from the southeast across South-Central Texas and the airmass over our CWA remains warm and moist with temperatures and dewpoints within a couple of degrees of where they were 24 hours ago. The subtropical ridge will strengthen over the next 24 hours and the low level flow will continue from the southeast. The upper ridge will suppress any convection. Temperatures will be steady through the short term. Lows Wednesday and Thursday will be about the same in the low to mid 70s. Highs Wednesday will be about the same as today in the 90s. Dewpoints will be a few degrees lower than the last several days and heat indices will be mostly below 100 degrees.
LONG TERM
(Thursday through next Tuesday)
Issued at 1257 PM CDT Tue Jun 23 2026
The subtropical ridge will continue to dominate over the region through the rest of the week. The low level flow will also continue from the southeast. There will be little change in the weather through the long term period. Temperatures will be fairly steady through the end of the work week and good mixing will keep heat indices below advisory criteria.
AVIATION
(18Z TAFS)
Issued at 1215 PM CDT Tue Jun 23 2026
Low level mixing has begun to increase which is allowing MVFR ceilings to lift to VFR for the start of the 18z TAF cycle. As ceilings diminish, an increase in gusty southeasterly winds is expected. These gusty winds will persist until sunset. Another MVFR deck is anticipated to develop once again after midnight for each terminal much like the previous nights. Hi-res models continue to show potential for spotty IFR ceilings along the I-35 corridor however, confidence on which terminal sees these degraded ceiling and at what time is too low to insert into prevailing.
The low ceilings will mix out Wednesday after 16z for each terminal.
