.DISCUSSION...

It looks like the moisture outran the freezing temperatures
tonight, which meant no snow for areas west of the Plateau.
There`s a small chance of light snow on the upper Plateau, but
that is quickly diminishing as the little remaining moisture exits
to the northeast. There may still be a few slick spots on back
roads during the morning commute as wet roads freeze. Thursday
will start cool, but temperatures are expected to warm near 40 in
the west and in the mid 30s in the east. We may even see a glimpse
of sun in the afternoon hours as the lower levels mix out and
clouds thin. A quick moving shallow band of moisture is forecast
to swing through the mid state overnight Thursday night and could
bring a few flurries to the area. No accumulation is expected.
This wave will also bring a surge of arctic air and drop
temperatures into the teens by early Friday morning. With cold air
advection still in place, Friday will be a cold day. Temperatures
may struggle to rise above freezing, although skies should be
mostly clear.

Northwest flow will continue this weekend as the persistent upper
trough remains in place. Afternoon temperatures are expected to
rise into the 40s both Saturday and Sunday. Another quick clipper
system could bring light snow to the Upper Cumberland late
Saturday night and early Sunday morning. Very little accumulation
expected with this wave. A brief warmup on Monday is forecast to bring
temperatures into the 50s for much of the area, but rain will be
on the heels of the warmer temps as the next storm system sweeps
across the mid west and into the Tennessee Valley Monday night.
Precipitation will enter from the northwest as rain, but will
transition from rain to snow as temperatures fall below freezing
Tuesday morning. Temperatures will likely fall throughout the day
on Tuesday, forcing any remaining moisture to transition to snow.
Some accumulation is possible on Tuesday, but amounts remain
unclear and changes in this system are likely as this is still
over 5 days out. Model agreement is okay right now, with minor
differences in moisture depth and speed of the system. Either
way, we should see a surge of arctic air behind Tuesday`s front
that will likely stick around for at least a couple of days,
making for a frigid middle and end of the work week. Currently
expecting lows in the teens and daytime highs near freezing.

12Z TAF DISCUSSION.

Snow showers near CSV expected to move out early this morning
and a clearing trend is expected to begin. MVFR/IFR CIGs will
improve this morning first at CKV then quickly BNA/MQY, then
finally CSV around midday. CIGs will return tonight...and
possibly a few flurries as an arctic front sweeps by. CIGs
are largely expected to remain above 3kft except maybe CSV.
This front will bring gusty northwest wind back to the area
for most of tonight.
