Area Forecast Discussion
National Weather Service Morristown TN
323 PM EDT Mon Oct 16 2017

.SHORT TERM...(Tonight and Tuesday)...
Higher pressure is building in across the region behind last
nights cold front this afternoon with skies mostly sunny
southwest and partly cloudy northeast. Temperatures were slow to
warm into the 50s and 60s from lows in the 40s and 50s this
morning. Strong north to northeast winds have also added to the
fall chill in the air this afternoon. Gusts from 20 to 30 miles
per hour occurred over the southern Tennessee valley earlier
today. Tonight skies will be mostly clear with winds subsiding
this evening but will stay up enough that temperatures will fall
slowly to the upper 30s to lower 40s. The highest elevations of
the mountains in east Tennessee and southwest Virginia lows will
drop to around freezing and in higher valleys of northeast
Tennessee...southwest Virginia and southwest North Carolina where
winds become light...patchy frost will likely form. The areal
coverage however will not be big enough to issue an advisory.
Tuesday temperatures will be a few degrees warmer as the surface
high shifts east and winds become light northeast.

.LONG TERM...(Tuesday night through Sunday)...
High pressure will dominate area weather through much of the
extended. This will allow for continued dry conditions with mostly
clear skies. Cool air filtering into the area will allow lows
Tuesday night to fall into the mid 30s to mid 40s range. Locations
where temperatures drop into the mid 30s may see patch frost
develop early Wednesday morning. By Wednesday afternoon...will see
a warming trend begin with temperatures warming each day. By the
weekend...expect both highs and lows to average around 5 degrees
above normal. The next weather system...a weakening cold
front...will be approaching the area around the Monday time frame.
Confidence low on timing and strength...but will introduce a
chance of showers.
