.SHORT TERM...
(Today through Wednesday night)
Issued at 1200 AM CDT Mon Sep 15 2025
A ridge aloft remains centered over Mexico this morning while
extending into the NW gulf, TX, and LA. An upper low is over the
SE states while another upper disturbance is over the Pacific NW.
At the surface an area of high pressure is centered along the
Louisiana coast.
Today, much like Sunday, will be warm and generally dry. However
and isolated afternoon shower or storm can not be ruled out. Pops
of 10 to 20% have been added to the forecast today, and chances
look the highest along the sea breeze. The mid lvl inversion in
association with the ridge should keep most convection that does
develop limited, however a lightning strike or two will be
possible.
Tuesday into Wednesday the upper disturbance over the SE states
may slightly retrograde to slightly weaken the ridge aloft
locally. Rain chances are again expected to range from the 10 to
20 percent Tuesday, but increase slightly into Wednesday.
The ridge at the surface is forecast to remain in place keeping
winds light.

.LONG TERM...
(Thursday through Monday)

The upper disturbance over the the Pac NW will move into the
central sections of the country for the second half of the week.
This may erode the ridge slightly and allow the continuance of
isolated afternoon showers and storms.
No fronts are forecast to enter the region. Temperatures will
remain sightly above normal.
