.DISCUSSION...
(Sunday through next Saturday)
Issued at 1046 PM CST FRI NOV 28 2025

Saturday will be dry with moisture slowly returning late in the day
as low level flow transitions to out of the south and southwest.
Saturday night, a low pressure system will move across the Ohio
Valley, with a trailing frontal boundary moving through the
southeastern US. The front is expected to moved west to east late
Saturday night into Sunday morning, weakening as the parent low
moves north and weakens. There is little to no instability for any
activity to work with, though with a strong mid level jet associated
with the boundary, there is plenty of 0-1 km shear, especially
across the north and west where the front and forcing will be
strongest.

Would expect general showers and thunderstorms through the night and
Sunday morning, with activity weakening and moving to the east with
the boundary through Sunday afternoon. Sunday night, a weak low will
develop across the lower MS River Valley, with a warm front moving
north through the area beginning Monday morning. There is a fairly
decent chance of low level moisture remaining from the south and
southwest Sunday afternoon behind the front. Lows Sunday night will
be in the mid 20s in the north and lower 40s in the south. However,
winds are expected to be brisk enough for wind chill values to be
around 5 degrees lower than the posted temperature, with values in
the north to be around the upper teens.

Moisture will slowly increase through the day Monday from south to
north, with values ranging from less than 90th percentile for this
time of year to near max by the afternoon. A cold front will then
swing through the area from the west late Monday night into Tuesday
early afternoon. Similar parameters as the Saturday night system
with little to no instability, weak forcing, but plenty of low level
shear. Will advertise a few strong storms possible, but nothing
severe on radar at this time.

By Tuesday night, models are in decent agreement about high pressure
and cool and dry air advecting into the state. Lows Tuesday night
will be in the low to mid 20s in the north to the low 30s in the
south. Dry weather will prevail for a couple of days when models
begin to diverge slightly on the next system. General consensus is
of a trough and low pressure moving across the northing extent of
the CONUS, with rain beginning as early as Thursday night for some
models, and Friday afternoon for others. Will leave as a
compromise through the middle and adjust as we get closer.

.AVIATION...
(06Z TAFS)
Issued at 1046 PM CST FRI NOV 28 2025

VFR conditions will prevail through the TAF period. A front will
bring an increase in moisture with increasing cloud cover, though
there is a low chance this will occur before the end of the TAF
period. With low confidence is these impacts, let mention out of
each TAF for now.

.FIRE WEATHER...

A very dry airmass will persist through Saturday with afternoon
RH values around 25 percent, especially at a few spots in our
southeastern counties. 20 foot winds of 5 to 10 mph are expected
Saturday, shifting from the northwest on Sunday. Moisture will
increase Saturday night as a wet pattern takes shape through
Tuesday.
