.DISCUSSION...
Light to moderate showers with an isolated thunderstorm or two
continues across many locations this afternoon as strong
shortwave continues to move into the base of long wave trof across
the central US. A weak coastal surface trof is also noted in the
surface analysis this afternoon. The clouds and showers have kept
temperatures from increasing much this afternoon. The cold front
is still situated well to the north of the area but is rapidly
moving to the south.

Showers and isolated thunderstorms will continue to move east
across the area remainder of this afternoon and into south central
louisiana late this afternoon and evening. A brief break in the
activity is possible this afternoon and early evening across
southeast Texas and western Louisiana. But guidance is insisting
on additional activity developing with the front.

Once the front passes, shower activity will come to an end with
temperatures cooling down once again with freezing conditions
likely across much of central Louisiana Thursday morning.
Temperatures will begin to moderate Friday and into the weekend
with dry conditions.
