DISCUSSION

Issued at 1115 PM CDT Fri Aug 7 2026

No major changes to the forecast. Hot weather and daily rain chances can still be expected through early next week. Ridging is currently situated over the Four Corners/off the East Coast. A weakness between both has resulted in lower heights & subsidence, which should allow for scattered showers and storms each day into next week. Expect most of this activity to occur during the daytime along the sea breeze, generally across the southern 2/3rds of our CWA. Lowering heights and the arrival of deep tropical moisture will bring the highest rain chances on Sunday and Monday. Daytime temperatures throughout the time frame will still be fairly hot, especially in spots that don't receive rainfall, with highs in the 90s and heat indicies in the triple digits. Would be worth practicing heat safety still, especially for those spending extended time outdoors. Patchy fog may develop in spots during the early morning hours.

Around Tuesday, 850mb temperatures begin to rise again as ridging builds across the northwestern Gulf. Afterwards, temperatures and heat indicies slowly rise while rain chances decrease.

AVIATION

(00Z TAF Issuance) Issued at 757 PM CDT Fri Aug 7 2026

VFR conditions expected for much of the TAF period, with the exception of MVFR cigs and reduced visibilities (from patchy fog) developing Sat morning from 10-14Z. Cigs will lift and scatter out and fog (if any) will burn off shortly after 15Z. Winds will be shifting from S-SW to S-SE Sat afternoon, with speeds around 08-14 KTS. There's also the potential for iso-sct showers and storms in the afternoon. IAH, HOU, CXO, and SGR are the most likely sites to be affected by these storms. Expect VRB and gusty winds, lightning, and periods of heavy rain with these storms. Rain chances decrease in the evening as diurnal heating decreases and the environment becomes more stable. Look for clearing skies and winds gradually decreasing early Sat night.

Cotto

MARINE

Issued at 1115 PM CDT Fri Aug 7 2026

Onshore winds 10-15 knots and seas of 2-4 feet are expected throughout the next several days. Rain chances increase slightly through early next week. Chances for scattered showers and storms will be greatest during the early morning through early afternoon hours for the Gulf. Shower and storm coverage may become more widespread on Sunday and Monday.
