.SHORT TERM...
(Tonight through Thursday)
Issued at 1011 PM CDT TUE MAY 20 2025

Right now a small area of showers and thunderstorms is moving
through the northern third of the area this evening. We are seeing
some additional activity developing in central MS and sliding
northeastward as well. Around midnight we may see both areas begin
to fill in and form a descent line as it moves southward. The
storms that have develop have been troublesome at times, so would
expect it to continue through the next few hours. PoPs are updated
and out.

.LONG TERM...
(Wednesday night through next Monday)
Issued at 1245 PM CDT TUE MAY 20 2025

Very little change with this long term forecast update. We remain
dry and slightly cooler in the wake of a cold front. Our "coolest"
day looks to be Friday with highs in the 70s and lows in the 50s for
those across our northern counties. Our unsettled pattern returns
over the weekend as a series of upper level waves move through the
region. This will bring low to moderate chances for showers and
storms through the holiday weekend and into next week.
