This Hazardous Weather Outlook is for Middle Tennessee.

.DAY ONE...This afternoon and tonight.

A Winter Storm Warning is now in effect from 6 pm this evening
through 6 am tomorrow morning. A Winter Weather Advisory remains in
effect for several counties south of I-40 this evening and tonight.
Light rain will develop across Middle Tennessee this afternoon, with
the rain rapidly changing to snow late this afternoon and evening
before ending. Snow accumulations ranging from a dusting in southern
Middle Tennessee up to 2 inches are possible, with pockets of up to
4 inches near the Kentucky/Tennessee state line and especially on the
northern Cumberland Plateau. Any snow accumulation or leftover rain
water on area roadways will quickly freeze into ice tonight as
temperatures drop, causing hazardous travel conditions overnight and
Friday.

A Wind Chill Warning also remains in effect for all of Middle
Tennessee from late this evening through midday Friday. Gusty winds
up to 40 mph will cause wind chills to drop as low as 25 degrees
below zero at times. Such cold wind chills could rapidly cause
hypothermia, as well as cause frostbite on exposed skin in as little
as 30 minutes. Outdoor pets and other animals should be brought
indoors or given extra protection and shelter to survive these cold
wind chills.

Dangerously cold temperatures are also expected across Middle
Tennessee tonight, with temperatures rapidly falling from the 50s to
near zero. Such a rapid temperature drop combined with gusty winds up
to 40 mph could cause exposed or unprotected pipes to rupture, as
well as result in isolated power outages.

.DAYS TWO THROUGH SEVEN...Friday through Wednesday.

Dangerously cold temperatures will continue across Middle Tennessee
through early Monday, with lows in the single digits and highs only
in the 10s and 20s. Temperatures are expected to remain below
freezing for up to 85 hours, which could cause exposed or unprotected
pipes to rupture, as well as result in isolated power outages.

.SPOTTER INFORMATION STATEMENT...

Spotter activation may be needed. Please relay any information about
observed severe weather to the NWS while following all local and
state guidelines.
