Area Forecast Discussion...UPDATED
National Weather Service Morristown TN
1045 AM EST Tue Nov 20 2018

.DISCUSSION...A upper trough axis is moving across the area this
morning with colder air aloft helping to steepen the lapse rates.
The low-level instability is producing scattered showers. Some of
the precipitation will be snow across the highest elevations,
generally at or above 4kft. So places like NewFound Gap, Roane
Mountain, and High Knob will see some snow showers. Snow
accumulations less than 1 inch expected.

Have made some minor changes to hourly temperatures and highs
given readings are running a couple degrees warmer than forecast.
Cold air advection behind frontal boundary will keep temperatures
from rising much if any today.

Have a great day.
