.DISCUSSION...
(Tonight through next Thursday)
Issued at 1056 PM CST Thu Dec 4 2025

The precip from the shortwave that moved through early Thursday
afternoon has largely come to a close, clearing out much faster
than guidance had anticipated. What we are left with around
midnight is a few light returns on the radar, which is more of a
fine mist than any falling precipitation. This does raise a
little bit of a concern about freezing fog overnight since
temperatures are already right around freezing and will continue
to fall overnight. On that same note, a Special Weather Statement
has been issued for patchy black ice for much of the area through
sunrise Friday. Several areas along the I-40 corridor still have
water on the ground from Thursday`s rainfall, which has the
potential to flash freeze into slick spots. This will mainly
impact bridges and overpasses, especially in rural areas. This
black ice threat should be over by mid morning at the latest;
temperatures will rise back above freezing and roads will have
plenty of time to dry up throughout the day.

With the exception of some light showers (15-20% chance) on
Sunday associated with a messy surface pattern, chilly and dry
conditions will prevail through the beginning of next week. We`re
locked into a pattern that is leaning below normal (40% chance)
for at least the next week due to persistent northwest flow
aloft. For early December, "below normal" means lows generally
around freezing and highs in the upper 40s to low 50s. With
little to no moisture upstream, it`s looking like the forecast
will remain predominantly dry through midweek. Another weak
frontal passage may encourage another round of showers on
Wednesday, but temperatures will be far enough above freezing to
preclude any winter impacts.

.AVIATION...
(06Z TAFS)
Issued at 1056 PM CST Thu Dec 4 2025

LIFR conditions across the airspace with the exception of JBR as
mist has developed accompanied by low cigs for much of the area.
Very little confidence that conditions will improve overnight, so
doubt there will be many improvements until the morning when
clouds will finally begin to lift. Considerable uncertainty into
tomorrow night, Generally northerly winds will become southerly
by the end of the current TAF period, remaining between 5 and
7 kts.

&&

.FIRE WEATHER...
Issued at 1056 PM CST Thu Dec 4 2025

No fire weather concerns for the foreseeable future with MinRH
values remaining above 40%. Other than some sporadic showers on
Sunday, chilly and mostly dry conditions prevail through midweek.
