.DISCUSSION...
(This afternoon through next Tuesday)
Issued at 1030 AM CST Wed Nov 5 2025

Another pleasant, albeit a bit warm, day across the Mid-South with
a few clouds currently traversing the area. Zonal flow aloft will
give way to a weak upper-level ridge into tomorrow, with a weak
trough developing into Friday. This will keep temperatures in the
above-normal range through Saturday, with high temperatures
spanning the mid 70s today and tomorrow and the mid to upper 70s
Friday and Saturday. By Friday, with the developing upper-level
trough, a weak cold front will push towards the area. There is
still considerable uncertainty along this frontal boundary, but
there is the potential for a few strong to severe thunderstorms to
develop. Right now the biggest question mark will be our
instability, with CAMs just now reaching the Friday period not as
excited as some other guidance. Low-level jet will begin to
strengthen by the afternoon to evening, so if we can capitalize on
any instability all modes of severe weather would be possible.
The best potential does appear to be east of the Mississippi
River, with the highest joint probabilities closer to the TN River
and NE MS / NW AL. Certainly something to keep an eye on, but
there is too much uncertainty and spread in the guidance currently
for this to be anything more than a low confidence event. Isolated
to scattered showers will remain in the forecast on Saturday, but
should be confined to the eastern half of the area.

By Sunday, a reinforcing frontal boundary will move through the
Mid-South with a deepening trough axis across the region. This
will usher out any lingering precipitation as well as knock
temperatures back to well below-normal through Tuesday. In
addition, low temperatures will be some of the coldest we have
seen so far this season Monday and Tuesday mornings. There appears
to be a high chance (>70%) of an area-wide freeze with a medium
chance (40-60%) of a hard freeze (
