KEY MESSAGES

Updated at 542 AM CDT Tue May 12 2026

- Seasonal temperatures and drier conditions this week.

- Rain chances increase by late weekend.

DISCUSSION

Issued at 129 AM CDT Tue May 12 2026

Surface high pressure will shift eastward today, allowing winds to become lighter and gradually transition to become south- southeasterly. This will increase low-level moisture, beginning a gradual warming trend and increasing humidity through the middle of the week. Although mid-level ridging will dominate the large-scale pattern and suppress precipitation, increasing Gulf moisture may lead to periods of greater cloud cover, especially during the overnight and morning hours. Afternoon highs over the next several days are expected to steadily climb into the upper 80s and low to mid-90s inland, with overnight lows eventually reaching the upper 70s as humidity increases.

By the weekend, the aforementioned ridge is forecast to weaken, and a more west-southwesterly flow develops aloft as a trough digs south and eastward. This pattern may allow weak disturbances to approach from the west, leading to the return of isolated shower and thunderstorm chances (20-30%) late Sunday into Monday. Given the extended forecast timeframe, confidence regarding precipitation potential and overall coverage remain on the lower side at this time. Forecast details will continue resolve as we go through the week.

AVIATION

(12Z TAFS) Issued at 542 AM CDT Tue May 12 2026

VFR conditions will continue through the TAF cycle. There is a low chance of patchy fog around sunrise for VCT and ALI, but with relative humidity values currently below 95%, have not put this mention into the TAFs. Light north to northeasterly winds will gradually turn back to the southeast through today.

A gentle to moderate northeasterly breeze (BF 3-4) is expected to continue through Tuesday before turning to the southeast and relaxing to a light to gentle breeze (BF 2-3) Tuesday night through Thursday. Winds will increase to moderate levels once again Thursday night and continue into the weekend. Little is expected in the way of precipitation through the period.
