  than normal night time lows tonight.
- Temperatures will warm Wednesday and the latter part of the

.SHORT TERM...
(Tonight through Friday night)
Issued at 1244 PM CDT Wed Sep 10 2025
Some low level moisture moving west along the coast this afternoon
may allow for an isolated shower or storm, however anything that
forms is expected to dissipate with the loss of daytime heating at
sunset leaving the first period shower free.
For the remainder of the short term, expect an upper level ridge
over Texas to build eastward into the forecast area reinforcing
the dry and subsident air aloft. This is expected to keep any
significant shower activity from developing.
The air mass over the forecast area will gradually modify with
daytime temperatures around the summertime hot values with night
lows close to the climo norms. Meanwhile, afternoon heat index
values will be kept in check by mixing and lowering afternoon dew
points.

appreciable chance for rain in the forecast.
With mainly sunny skies, and a light east-southeast flow in the
low levels, air temperatures are expected to be summertime hot
during the daytime and mild at night. Afternoon mixing with the
dry air aloft is expected to keep max heat index values in check
and near or slightly above the air temperature.
