.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) Issued at 1200 AM CDT Mon Sep 15 2025
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.
