A strong cold front will bring much colder air to East Tennessee and the Southern Appalachians by Friday, Nov. 13. Rain is expected to turn to mountain snow showers.
The National Weather Service in Morristown says highs will stay in the 40s Friday and Saturday, running 10 to 15 degrees below normal.
First snow in the mountains
Scattered rain will change to snow showers in the mountains late Thursday night into Friday.
Higher elevations can expect minor snow accumulation Friday into Saturday. NWS rates the impact as minor, meaning winter driving conditions and a few inconveniences.
Forecasters say there is still uncertainty over how much precipitation will fall as snow rather than rain.
Wind chills in the 10s and 20s
Brisk northwest winds will drive mountain wind chills into the 10s and 20s Friday and Saturday night.
Valley lows fall to the upper 20s and low 30s Friday and Saturday nights, well below the mid 40s to low 50s of midweek.
A sharp turn from midweek warmth
Wednesday is the last pleasant day of the week, with sunshine and highs of 65 to 70 degrees.
A cold front moves through Thursday with showers. Highs reach only 54 to 60 degrees, and lows drop into the mid 30s.
Friday brings isolated showers with highs of 41 to 50. Saturday is partly sunny and similar, at 42 to 51.
What to do
Dress in layers and protect pets and sensitive plants from the cold.
Use caution on mountain roads Friday morning. Monitor weather.gov/mrx for updates.
