DISCUSSION

Issued at 141 PM CDT Wed Jul 29 2026

High pressure will remain in control of the pattern through the end of the week, continuing our hot and dry weather. The HeatRisk will remain moderate to major, with isolated locations experiencing an extreme HeatRisk. With no significant shift in the pattern, have used the observed forecast dewpoints as guidance for 04Z-19Z Thursday as models continue to forecast values a bit higher than recent observations. Based on this, it looks like a heat advisory will not be necessary for Thursday, though isolated locations could have heat index values around 110. Moisture will likely return this weekend, returning the need for Heat Advisories. Folks spending time outdoors this weekend should practice heat safety as heat index values of 110+ will be likely along the inland Coastal Bend.

The forecast begins to get a little murky by Sunday as the trailing edge of mid-level trough to our northeast moves across the eastern periphery of the high pressure. This could introduce a few showers across South Texas, with the main focus over the Victoria Crossroads and Coastal Bend.

AVIATION

(18Z TAFS) Issued at 141 PM CDT Wed Jul 29 2026

With little to no change in the pattern, have mostly used last night's observations as a guideline for tonight through Thursday morning. If conditions hold as expected, there will be brief MVFR ceilings at ALI and COT in the early morning hours. It is possible that CRP could experience this as well, but it seems less likely so have not included this in the TAF.

MARINE

Issued at 141 PM CDT Wed Jul 29 2026

A gentle to moderate (BF 3-4) onshore flow will persist through most of the period, with fresh (BF 5) breezes the evening and overnight hours across the southern bays and nearshore waters. Winds will increase slightly to a moderate to fresh (BF 4-5) over all the waters Sunday, before returning to a gentle to moderate flow early next week. Seas will remain around 2-4 feet. Dry conditions are expected through the forecast period, though a low (15-20%) chance of showers and storms will return to the northern offshore waters this weekend.
