The National Weather Service issued this Winter Weather Advisory:
A cold front will approach Middle Tennessee tonight with moisture increasing ahead of it.
Moisture will overspread a cold air mass already in place while the atmosphere a few thousand feet up will be warming. This will produce prime conditions for freezing rain and sleet.
Temperatures at the ground will gradually warm late tonight and Friday and change most of the precipitation to rain. However the period of time when surface temperatures are freezing will be the time when ice accumulation on trees and power lines will be likely and glazing of roads will be possible.
Eastern of the midstate will likely have the longest period of freezing rain and sleet and, as a result, some of the larger ice accumulations.
The main impact will be icing of trees, power lines and roads. Ice accumulation up to 2/10ths of an inch.
A winter weather advisory means that periods of freezing rain and sleet will cause travel difficulties. Be prepared for slippery roads and limited visibilities – and use caution while driving.
