.SHORT TERM...
(Today through Wednesday night)
Issued at 322 AM CST Mon Nov 25 2024

High pressure continues to depart the southeast states as a low
pushes into the plains. A cold front is also moving south across
the TX Panhandle and OK. Between these systems the local south
flow is increasing moisture and temps. A few sprinkles are noted
over the gulf waters this morning. While not mentioned in the
forecast, a very brief light shower is possible along the coast
through the morning, but overall coverage is minimal.

Today the front will advance southeast across TX. A few showers
will become possible during the late afternoon across interior SE
TX and Cen LA as the front moves closer. The boundary will
advance through Acadiana by early morning Tuesday. Showers, even a
thunderstorm or two may be possible, but overall accumulation is
anticipated to be light.

A brief cool down and drying out is expected behind the boundary
that will last into Wednesday. The warm front will lift north by
afternoon or early evening as yet another low pressure system
pushes across the southern plains and Mississippi Valley. The
associated cold front will move into the SE TX Lakes region during
the early morning Thursday or just past midnight. While
instability will be lacking an isolated strong storm can not be
completely ruled out ahead of the approaching cold front that
should clear the gulf coast early during Thanksgiving. Gusty winds
will be the main concern with any strong storm, but overall
chances for rain is a low 10 to 30 percent.
