No major changes will be made to the forecast for the very cold
and snowy weather coming our way. A Winter Storm Warning remains
in place area-wide from 6 PM today until 6 am Tuesday.
Snow was already crossing the Ms River early this afternoon.
Short range models show the snow spreading rapidly eastward into
our area late this afternoon and evening. Snowflakes should start
to fall in our western counties by 4 or 5 PM. By midnight, the
ground will likely be covered for most areas along and west of
I-65 with an inch of fresh powder, and up to 2 inches for some
spots. By daybreak Monday, much of the Mid State will have snow
cover, averaging 1 to 3 inches. Then, the second main wave will
move across the area late Monday morning through afternoon with
the greatest additional accumulations focused along a band from
Waynesboro and Lawrenceburg northeast to Crossville and Jamestown.
Models have become as agreeable and consistent as we can hope for
with winter wx in our region. We are still expecting all snow with event
totals averaging 1 to 3 inches over our northwest counties and 4
to 7 inches across our southern and Plateau counties. Areas around
Clarksville could come up a little short, especially with the
second wave tomorrow falling mostly south of I-40. Some spots in
the main band across the south and Plateau could over-achieve with
7-8 inches under locally enhanced bands. Nashville Metro is on the
edge of the higher band, so a small shift in this band could raise
or lower totals for Metro.
The snow will taper off Monday night as temperatures plunge
further. Lows by Tuesday morning will be around 10 degrees with
wind chills down in the single digits below zero for much of the
area. A wind Chill Advisory will likely be needed, but we will
wait til later tonight or Monday before focusing more on the cold.

After the snow leaves, bitterly cold, dry air will grip the Mid
State Tuesday through Wednesday. A fresh blanket of snow will
enhance the cold temperatures. Highs will be limited to the teens
for many areas on Tuesday and down near zero Tuesday night. The
snow on the ground will not go anywhere through midweek with these
frigid, yet not record-setting temperatures.
Temps will finally climb above freezing Thursday just before
another system comes our way with another chance for snow and
another blast of Arctic cold air. Latest models show potential
for up to an inch of snow with this fast moving system late
Thursday through Friday followed by more bitter cold and dry air
for the weekend.
