.DISCUSSION...
Issued at 1001 PM CST Mon Nov 24 2025

Will be brief as active weather still plaguing southern and
eastern portions of our CWA. Tornado Watch #639 still in effect
for portions of Deep East Texas and Northern Louisiana through
1 am. Radar trends over the last hour or so has shown a decrease
in convective intensity but there is still a west to east oriented
warm front bisecting northern Louisiana south of the I-20
Corridor. Most intense portion of the broken line of storms is in
this warm sector or due east of the Toledo Bend Reservoir so we
are not out of the woods per say yet but near or after 1 am we
should be close clearing the strongest convection east of our
region.

What we are seeing in the wake of this convection is very
low ceilings which continue to lower and the end product will be
areas of dense fog setting up across the western third of NE TX
into SE OK attm. Will wait to see how this fog progresses eastward
with time overnight but I would not be surprised if a Dense Fog
Advisory becomes necessary for at least portions of our region
through the mid morning hours on Tuesday. One more warm day
forecast today ahead of a strong cold front that will enter our
region late into the afternoon but more likely during the evening
and overnight hours Tuesday Night bringing with it much cooler
temperatures and dewpoints.

Near normal temperatures for late November can be expected with
this post frontal airmass coming in with freezing temperatures
likely Wed Night and Thu Night across our far northern and
northeastern zones both nights.

Rain returns as early as Saturday across the entire Four State
Region in advance of a weaker upper level trough and while this
trough is not nearly as amplified as the current one we are
dealing with, southwest flow aloft will follow the weekend trough
which will keep rain chances in the forecast through the early to
middle part of next week as well.

.AVIATION...
(06Z TAFS)
Issued at 1153 PM CST Mon Nov 24 2025

For the ArkLaTex terminals, line of TS from Toledo Bend Dam to
just now working east of KIER/KMLU. Cloudy in the wake of the line
with 0-2 degree T/Td spreads and heavy fog and low stratus likely
to affect many of our sites with 0-5KT of wind until after
daybreak. Looking at VLIFR for many sites by then, but with a
decent pace to lift and scatter as the W/NW wind attains some
speed 5-10KT by 15Z-18Z. The fropa will occur late day and remain
dry under fair skies, but turning much colder for Thanksgiving. /24/

.SPOTTER INFORMATION STATEMENT...
Issued at 1001 PM CST Mon Nov 24 2025

Spotter activation will likely continue across portions of the
region for the next few hours. The remainder of the week looks
uneventful weather wise and spotter activation is not likely.
