KEY MESSAGES

- Mostly stable weather for the work week with just some sea-breeze showers and thunderstorms today and Tuesday.

- Humid air could send heat indices into the the triple digits for most areas through the week.

SHORT TERM

(Tonight through Tuesday night) Issued at 129 PM CDT Mon Jun 8 2026

Regional radar imagery shows seabreeze showers and occasional thunderstorms over the I-35 Corridor and eastward into the Coastal Plains. With additional cloud cover expected under these showers, opted to lower Max T's a couple degrees further in line with CONSall/NBM blend. Expect highs in the upper 80s to lower 90s, with mid 90s expected along the Rio Grande. A muggy and warm night is expected with temperatures falling into the lower to middle 70s along with mostly cloudy skies.

Tuesday will feature yet another shot at rain, but it'll be quite a bit lower as mid-levels dry out a bit more and the seabreeze weakens as mid-level ridging strengthens. We will still carry 20-30% PoPs from east to west, with the higher chance for rain out west along the Rio Grande. Temperatures will climb higher as cloud cover thins out by early afternoon. Expect highs in the lower to middle 90s for most with the exception being in the Hill Country or Edwards Plateau where highs may remain in the mid to upper 80s. Any rain or isolated thunderstorms should quickly fall apart after sunset, as loss of diurnal heating will be their downfall.

LONG TERM

(Wednesday through next Monday) Issued at 129 PM CDT Mon Jun 8 2026

The long term looks hot and dry, but not without humidity as soil moisture remains high due to recent rains. Temperatures will steadily climb as mid-level ridging takes hold Wednesday through Saturday, with highs in the mid to upper 90s. Heat indices may climb into the 105-110 range by late week, but adequate mixing should limit things from getting too muggy in the afternoons. Ridging may start to break down by the back half of the weekend, with the potential for rain to reenter the picture early next week.

AVIATION

(18Z TAFS) Issued at 1239 PM CDT Mon Jun 8 2026

Scattered showers and a few thunderstorms continue across the region early this afternoon. Based on radar trends, we have added a TEMPO group to the I-35 sites for some brief MVFR cigs in SHRA. Will monitor for possible TSRA as well, but coverage of storms should remain fairly limited and mainly confined to areas east of I-35. Otherwise, expect SCT-BKN VFR clouds this afternoon and early evening, with MVFR returning to the I-35 sites around 05Z and to DRT around 07Z.
