KEY MESSAGES
Updated at 135 AM CDT Sun Aug 30 2026
- Hot and dry weather returns with temperatures in the mid to upper 90s to near 103 through the next week.
- Slight chances for seabreeze showers and storms early next week especially for the Coastal Plains.
SHORT TERM
(Today through Monday) Issued at 135 AM CDT Sun Aug 30 2026
Humidity should drop off a bit Sunday as increased sunshine and dry weather continues for the second half of the weekend. The Subtropical Ridge remains centered over north Texas early this morning but will slowly migrate to the east on Monday. This will keep things hot, but not as hot as we'd seen in the 2 weeks leading up to Thursday and Friday's rains. Sunday and Monday will be hot and dry with weak flow aloft and highs in the mid to upper 90s to around 100.
LONG TERM
(Monday night through Saturday) Issued at 135 AM CDT Sun Aug 30 2026
On Tuesday, an inverted trough will move inland from the Gulf, but it will be an open wave with very little upper-level support. The only areas that might see some rain Tuesday and Wednesday are the Coastal Plains as seabreeze showers and storms attempt to move further inland. Ridging may finally begin to breakdown by next weekend, with a more active pattern possible as flow turns more northerly. For now, we will remain optimistic about a pattern shift for the region.
AVIATION
(06Z TAFS) Issued at 1228 AM CDT Sun Aug 30 2026
VFR skies continue early this morning as winds remain from the south to southeast along I-35, with easterly winds out west at DRT. There is some potential for low cloud development early this morning and for now, we will go with SCT low clouds for the I-35 sites around sunrise. For this afternoon and evening, south to southeast winds are expected along with VFR skies.
