Area forecast discussion...updated 
National Weather Service Morristown Tennessee 
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.
