KEY MESSAGES

- Shower and thunderstorm chances and coverage will be diminishing today and Friday compared to previous days.

- A more typical summertime pattern is expected this weekend and into next week with even lower (if any) rain chances.

- With more sun and drier air moving back in, look for daytime highs to climb back into the mid 90s.

DISCUSSION

Mid-upper trough that has been responsible for all the rain this week will continue tracking further west as higher pressure builds into the region from the east. PW's, previously in the 2.0-2.3" range, will be lowering...but still a respectable 1.7-2.0" at times through Friday. So, even though overall rain chances and coverage should be on a decline...I'd still anticipate some isolated-scattered activity the next few days.

Heading into the weekend and next week, lower moisture values combined with more predominate ridging (both in the llvls and aloft) should keep rain chances at a relative minimum. With the drier air place, we should see daytime highs climb back well into the mid 90s. 47

AVIATION

(00Z TAF Issuance) Issued at 639 PM CDT Wed Jul 15 2026

Rain chances will continue to decrease late this evening and winds will relax to 5 KTS or less tonight. MVFR cigs are possible over sites north of I-10 during the overnight to early morning hours, along with areas of patchy fog. Fog, if any, will burn off around 14-15Z. Cigs will gradually rise during the morning hours, but may remain overcast (mostly VFR) for much of the day. Iso-sct showers and iso thunderstorms can be expected throughout the day, mainly for sites north of IAH. Winds will be generally S-SE at 5-10 KTS Thu, relaxing to 5 KTS or less by the early night hours. MVFR cigs are possible again late Thu night into early Fri morning.

MARINE

Issued at 1235 AM CDT Thu Jul 16 2026

SE/S winds in the 12-17kt range will prevail for the next several days. Speeds will be highest at night offshore and during the afternoons/evenings in the bays. Scattered shower and storm coverage will be trending down from what we have experienced the past several days today and Friday...and even moreso this weekend and next week. Seas should mostly be in the 3-4ft range...maybe a touch higher beyond 40nm offshore. The center of surface high pressure will be moving into the northwest Gulf late in the weekend and early next week which should cause a reduction in speeds/seas and a more SSW component to the winds. 47
