.DISCUSSION...
(Tonight through next Wednesday)
Issued at 1015 PM CST Wed Nov 19 2025

A stalled front is located from Clarksdale, MS to Savannah, TN.
Light winds, low dewpoint depressions and some recent rain invof
the stalled boundary is setting the stage for dense fog. Several
sites have already dropped below one half mile. The latest HRRR
indicates additional dense fog development across NE MS and
eastern AR later tonight. Decided to go ahead with an area wide
Dense Fog Advisory through 10 AM Thursday.

An upper trough will begin lifting out of the SW US/northern Mexico
on Thursday. Increasingly moist SW flow aloft will impinge on the
stalled frontal boundary resulting in numerous showers and
embedded thunderstorms across much of the Mid-South, especially
along and north of the TN/MS line, Thursday into Thursday night.
South of the front, across north MS, coverage will be less and
temps will again approach 80 degrees on Thursday. By Friday, a
weak cold front will approach the area with rain chances spreading
over the entire Mid- South. Severe chances look very low with
poor instability and fading upper level support as the upper
trough rapidly weakens as it spread northeast. The weak cold front
will move through Friday night with the heavier precip
dissipating or pushing east.

Saturday will start out damp as the area remains under cyclonic
surface flow. Low clouds and some drizzle will likely prevail at
least in the morning with some improvement in the afternoon as
weak high pressure moves in. Saturday night looks foggy from this
far out. Upper ridging ahead of the next system and weak surface
high pressure should produce a nice day on Sunday with temps in
the 60s and 70s.

The next system will eject from the SW US/northern Mexico early
next week with rain chances Monday into Tuesday. This system
looks a little more potent though the details are still
unfolding. Enough moisture and instability may advect into at
least southern parts of the Mid-South to result in a low severe
weather chance.

.AVIATION...
(06Z TAFS)
Issued at 1015 PM CST Wed Nov 19 2025

Messy TAF set remains this issuance. A warm front has brought IFR
with intermittent LIFR conditions across the airspace and will
continue into the morning hours. Conditions should improve to
MVFR conditions by the afternoon. Prevailing -SHRA will also
impact terminals through much of the TAF period aided by the
aforementioned front. Light east winds will shift more
south/southeast by the afternoon hours.

Wetting rain chances return on Thursday and will persist through
the end of the week. MinRH values will remain above 50% for the
foreseeable future with additional rain chances returning next
week. Fire weather concerns remain low.
