Long Term
(Friday through next Tuesday) Issued at 233pm CDT Wednesday July 17 2024

Key Messages:

- Minor to moderate risk of heat-related impacts for the week

- Rain chances increase late this weekend into next week

Good news! There is very little change to the inherited long term forecast package. Models still indicate a more active pattern as the upper level ridge moves west and a trough digs south. A "cold front" will push into Texas, but will stall to our north. Moisture will pool ahead of this boundary with PWATs (Precipitable Waters) increasing to around 2 inches. A series of shortwaves will move along the trough, resulting in moderate (30-60%) chances of showers and thunderstorms across the area through the middle of the week. At this point, I think most of us agree that we will take any days with cloud cover, a chance for some rain, and heat index values below 110.

So...even more good news! With the increased cloud cover and chances for rain, highs will remain in the low 90s to around 100 degrees out west. Heat index values will remain in the 105-109 range, with only a moderate risk for heat-related impacts across the area. At this time, Heat Advisories do not seem likely, though a few locations could see heat index values touching 110 over the inland Coastal Bend.

Marine
Issued at 233pm CDT Wednesday July 17 2024

Weak to occasionally moderate southerly flow will continue tonight through tomorrow night. Rain chances increase tomorrow afternoon with a low to medium chance for rain. Weak to moderate onshore flow is expected with moderate rain chances through the middle of next week.
