  southeastern Kentucky. Light snow accumulations up to about 1
  inch is possible.

* A roller coaster of temperatures awaits us over the next several
  days. We will see highs in the low 30s and highs in the upper 40s
  on and off each day as cold fronts move through.

.UPDATE...
Issued at 907 PM EST Thu Dec 4 2025

At this hour, the initial surge of heavier precipitation is moving
through our Lake Cumberland counties. The 01Z RAP analysis shows the
850 mb 0C isotherm very close to that area, with the warmest
temperatures aloft actually showing up around 800 mb per RAP
soundings. As a result, areas along the TN border (in particular
Monroe, Cumberland, and Clinton County) appear to have changed over
to a wintry mix with sleet and possibly some rain mixing in. This
will likely cut down on snowfall totals, though some areas could
still see around 1 inch of snow and sleet through early tomorrow
morning.

Farther to the north and west, precipitation is all snow, though
precipitation rates are generally lighter. An additional band of
flurries and light snow showers is beginning to develop from around
Bowling Green back to near Clarksville, TN. Hi-res guidance suggests
this band should continue to strengthen over the next few hours and
pivot off to the east of I-65. The SPS looks to be well placed for
areas which could receive light accumulations of snow through early
Friday morning.

Along and north of the Parkways, cloudy, dry conditions continue
tonight, with temperatures in the upper 20s and low 30s. The main
changes to the forecast at this time were to increase sleet mention
across the Lake Cumberland region over the next few hours, resulting
in a decrease in overall snowfall totals.

.SHORT TERM /THROUGH SATURDAY/...
Issued at 307 PM EST Thu Dec 4 2025

Low-level moisture under an inversion continues to keep low stratus
over the region. We have seen some areas in southern Indiana and
northern Kentucky break out a bit. This has helped temperatures to
increase just above freezing.

This evening, a weak trough and plenty of CVA will move through the
region. An upper jet will place southern Kentucky under the right
entrance region. At the surface, a low pressure system over the Gulf
coast will extend an inverted surface trough into the lower Ohio
Valley. Present moisture (0.75-0.9 inch PWATs) and large scale lift
will allow for stratiform snow to move over southern Kentucky. There
is a region of enhanced frontogenesis and low-level convergence
along the trough that may lead to moderate snowfall over the Lake
Cumberland region for a few hours. Both deterministic and ensemble
guidance has indicated slightly higher snow totals as well.
Therefore, have issued a Winter Weather Advisory for the Lake
Cumberland region from 0Z to 12Z for snow totals around 1 inch. The
southeastern portion of the region (outside of the advisory) have an
SPS for totals around 0.5 inches. It is possible that some localized
areas will see slightly higher totals. Looking for a pretty wet snow
(lower than normal snow to liquid ratio). Therefore, we could see
some slick spots develop on roads.

Snow will push east of the region before sunrise, but clouds will
remain through most of the day. In the afternoon, we will begin to
break out from NW to SE. Conditions will remain dry and temperatures
a bit warmer than the previous days, in the upper 30s and some lower
40s. Friday night, low stratus will likely increase as low-level
moisture is present.

.LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/...
Issued at 307 PM EST Thu Dec 4 2025

On Saturday, a cold front will approach the region from the
northwest, as the parent upper trough swing through southeastern
Canada. This front will likely stall just northwest of the region.
Meanwhile, the lower Ohio Valley will see some WAA, which will help
temperatures increase into the upper 30s to mid 40s for highs on
Saturday.

On Sunday, a shortwave riding along the broader troughing will push
the cold front through the region and bring a chance for precip.
Given the previous WAA and timing of the system, would expect this
system to bring mostly rain, though it could begin as frozen precip
Sunday morning.

After the front pushes through, high pressure and strong CAA will
build in behind. Temperatures on Monday will be chilly. Wind chills
in the morning will be in the teens over most of the region.

Tuesday, we will see ridging build over the region and temperatures
warm to slightly below normal levels. Deep troughing looks to swing
through the region on Wednesday, bringing a low pressure system
through the northern Ohio Valley. Since we will be under WAA, expect
precip associated with this system to be mostly rain. Though strong
CAA and an occluding low could bring a cold air chasing wrapped
moisture scenario where we see some light frozen precip on Thursday.

.AVIATION /06Z TAFS THROUGH 12Z SATURDAY/...
Issued at 1222 AM EST Fri Dec 5 2025

Restricted flight categories will continue this morning as an area
of low pressure passes through the region and support continued low
cigs for the terminals. Periods of IFR and MVFR are expected through
at least the morning hours, however there is confidence that we will
begin to break out of this persistent stratus deck and may see
terminals return to VFR later on this afternoon and evening. Winds
for today will generally be from the south-southwest.
