KEY MESSAGES

- Seasonably hot with highs in the 90s and heat index values 100-107F each day. - An isolated late day shower can't be ruled out along the seabreeze later today and Wednesday, but most locations will remain dry. - Slightly better rain chances expected Thursday into early next week for southern parts of the region as some deeper moisture flows back inland.

DISCUSSION

Issued at 1251 PM CDT Tue Aug 4 2026

No significant changes were made to the ongoing forecast. With the exception of an isolated seabreeze/baybreeze shower or thunderstorm, subsidence and modest moisture levels should keep rain chances fairly low for the vast majority of the region. As the days progress Thursday into early next week, we should see heights fall just a touch across our coastal areas as the western ridge repositions just a bit further north. This, along with a developing fetch of SE llvl winds and higher PW's should allow for some better rain chances (mainly just scattered diurnally driven coverage) for our southern 2-3 tiers of counties. High temperatures should trend down a few degrees as well with the SE flow and more cloud cover. 47

AVIATION

(00Z TAF Issuance) Issued at 710 PM CDT Tue Aug 4 2026

Current VCTS associated with the afternoon sea breeze are being monitored around IAH. Remnants of the sea breeze will keep S winds elevated around 10 kts, gusting between 15-20 kts. Winds will relax becoming variable at 03-05 kts in the early morning hours between 05-12Z. Just before sunrise, CIGs and VSBYs could drop to MVFR and even VFR at some terminals such as SGR, LBX, IAH, and CXO due to light winds and overnight moisture supply. After sunrise, CIGs will gradually lift and scatter out and fog, if any, will burn off quickly and return to VFR conditions throughout the period. Winds will strengthen around 10 kts throughout the afternoon out of the S-SE. Sea breeze again brings gusts 15-20 kts and another round of PROB30 -SHRA, mainly around the I-10 corridor.
