KEY MESSAGES

- Steady warming trend through Wednesday.

- Low (20-40%) rain/storm chances return for the middle to end of the week.

SHORT TERM

(Tonight through Monday night) Issued at 1247 PM CDT Sun May 3 2026

Abundant sunshine with the return of south winds will bring highs into the mid 70s to low 80s today, roughly a 5 degree jump from those seen yesterday. Low level southerly flow increases late tonight bringing another increase in both temperatures and humidity for Monday. Wind increases in the morning tomorrow with a rather breezy day in store with gusts from around 20-25 mph. Low clouds return Monday night bringing back our warmer than normal low temperatures in the mid and upper 60s.

LONG TERM

(Tuesday through next Sunday) Issued at 1247 PM CDT Sun May 3 2026

Warm and humid conditions are expected into the middle of this week with highs from the mid 80s to mid 90s Tuesday and Wednesday. An upper trough moves across the Plains Wednesday with a cut off low meandering near the Baja Peninsula through late week. At the surface, a dryline will be over the southern Edwards Plateau Tuesday night where isolated thunderstorms could develop and move into the Hill Country by Wednesday morning with low precipitation chances spreading east to the portions of the I-35 corridor and coastal plains Wednesday. That said, the presence of a strong cap looks to be in place ahead of the dryline which will likely limit the ability for storms to develop.

A cold front arrives Wednesday night into Thursday morning briefly cooling temperatures for the latter half of the week. Highs in the 70s and low 80s are expected Thursday and Friday, with lows in the upper 50s and 60s. Low rain chances continue late week due to the aforementioned cut off low slowly drifting east towards the area with the potential for some disturbances to move out ahead of it. This upper low may finally shift over Texas this weekend bringing continued opportunities for rain.

AVIATION

(00Z TAFS) Issued at 600 PM CDT Sun May 3 2026

Winds will remain east-southeasterly to south-southeasterly across the region.
