KEY MESSAGES
Updated at 557 AM CDT Sat Aug 29 2026
- Hot and dry weather return with temperatures in the mid to upper 90s through the next week.
- Slim chances for seabreeze showers and storms early next week, but primarily for the Coastal Plains.
SHORT TERM
(Today through Sunday) Issued at 1243 AM CDT Sat Aug 29 2026
Active convection from earlier has ended. Temperatures should quickly fall into the 70s for any areas that have not yet already. On Saturday, mid-level ridging starts to push eastward into Texas again, and this will shut off our northerly to northeasterly mid- level flow that we've had the past 2 days, which has led to widespread showers and storms with gusty winds and heavy rainfall. Things continue to dry out on Sunday as the ridge slides east over northeast Texas, and highs will climb into the upper 90s to around 100.
LONG TERM
(Sunday night through Friday) Issued at 1243 AM CDT Sat Aug 29 2026
An inverted trough will try and slide under the ridge Monday into Tuesday, but at this point, it doesn't look like we'll see much beyond some seabreeze activity in the Coastal Plains, while dry weather persists everywhere else. Ridging remains to our north over the remainder of the week and that may open the door for additional tropical moisture to work inland by the end of the week.
AVIATION
(12Z TAFS) Issued at 557 AM CDT Sat Aug 29 2026
Satellite data hints at some low clouds developing east of the I-35 corridor early this morning. For now, we will keep the forecast VFR as low-level moisture looks favored farther east into the coastal plains. Otherwise, little change has been made to the current forecast with VFR expected through the period. We will continue to monitor for the possibility of some isolated convection over the coastal plains region today. With low confidence, we will not mention in the I-35 sites.
