A Winter Weather Advisory remains in effect from 3 a.m. to 6 p.m. CST Thursday.

Main impact: 1 to 3 inches of snow accumulation. The snowfall will stick to road surfaces with no melting and strong northwest winds will cause a period of blowing and drifting snow. This will cause travel problems or delays across the mid-state.

Aa surge of Arctic air will move into the midstate in the wake of the system and will drive temperatures into the single digits Friday night... with wind chill readings below zero.

A Winter Weather Advisory means that periods of snow will cause travel difficulties. Be prepared for slippery roads and limited
visibilities and use caution while driving.

Snow will accompany Arctic blast

A reinforcing Arctic airmass is diving down through the northern plains with temperatures in the single digits across the Dakotas at early afternoon. The leading edge of the Arctic airmass will move down into western Missouri this evening and into far western Tennessee around daybreak Thursday. Snow is already falling in advance of this system which will move into western middle Tennessee just before daybreak and then advance eastward during the morning and continue into the afternoon before tapering from the west.

The leading edge of the Arctic airmass is expected to pass through Nashville during the early afternoon on Thursday with winds shifting
to the west and becoming gusty. The leading edge of the Arctic air mass is expected to reach the plateau by 5 PM CST. Snow amounts
are expected to range from 1 to 3 inches.
