.KEY MESSAGES...
- Seasonably hot and humid weather will continue through the
weekend with little to no chance for rain.
- A low chance for showers and storms will return to parts of
Central and East Texas next week.
&&
.SHORT TERM... /Issued 1243 PM CDT Sat Jun 21 2025/
/Through Sunday/
Seasonable June weather will continue this weekend, with high
temperatures in the low to mid 90s and morning lows in the 70s. Rain
chances will be nil across the region as we remain on the periphery
of a strong upper level ridge centered over the eastern CONUS
(the feature responsible for the ongoing heat wave across the
eastern half of the country). Fortunately for us here in North and
Central Texas, the heat will remain relatively tolerable, with
temperatures running near normal for mid to late June. Breezy
south winds will continue through the weekend with wind speeds
near 10-20 mph and gusts up to 25-30 mph.

.LONG TERM... /Issued 1243 PM CDT Sat Jun 21 2025/
/Sunday Night Onward/
The upper level ridge axis will shift further north and east this
week, becoming increasingly displaced from North and Central
Texas. While weak ridging will continue to keep most locations
rain-free, low storm chances will return to portions of Central
and East Texas as seabreeze convection makes a run at our
southern zones during the afternoon most days this week.
Temperatures will remain near normal throughout the week, with
afternoon highs mostly in the low to mid 90s and morning lows in
the 70s. Heat index values will generally remain in the 95-102
degree range.
