Area Forecast Discussion
National Weather Service Morristown TN
404 AM EST Wed Jan 3 2018

.SHORT TERM (Today and Tonight)...
Kind of a lull today as the surface ridge slides to the east and
valley temps get above freezing for the first time in a few days,
then another cold front moves in tonight with gusty winds and very
cold wind chills.  Will have a wind chill advisory for parts of the
area, generally higher elevations, where temperatures will be
colder, but the winds will be quite a bit higher.  Also, the
temperatures coming in with this airmass will be in the dendritic
growth regions, even below 850 mb, so have included snow showers and
flurries for late tonight for the northern half of the area, but
with minimal accumulations for these few hours (since this forecast
period ends early Thursday morning) in the higher elevations.  These
conditions including the Wind Chill Advisory will continue into the
next period.

.LONG TERM...(Thursday through Tuesday night)...
A shortwave will dive southward and amplify the longwave trough
across the region on Wednesday night and Thursday with surface
high pressure to our northwest and a developing coastal surface
low off of the SE coast. The tight pressure gradient will result
in a northwesterly wind advecting in another shot of cold, Arctic
air to the forecast area. This also appears to be a favorable
setup for some northwest flow snowfall across the higher
elevations. Moisture will be limited, but Great Lakes influence on
air parcel trajectories should provide some additional, but
limited, low-level moisture. Also, the following factors seem to
support northwest flow snowfall: 1) the very cold airmass placing
the DGZ near the surface; 2) 850mb winds at 20-30 kt providing
good orographic lift across the higher terrain; and 3) an 850mb
trough axis dipping into the Southern Appalachians on Thursday
morning providing steep low-level lapse rates. These factors
support the potential for orographically enhanced precipitation
across the higher elevations and at least some flurries across the
lower terrain. With such a cold air mass, any small amount of
moisture and lift may produce at least a few flurries on Thursday
and Friday. Troughing remains for Friday and Saturday with
continued cold and max temperatures about 20 to 25 degrees below
normal. High pressure over the area should bring us mostly sunny
conditions on Friday, and especially Saturday, as high pressure
builds over the region.

Ridging at 850mb and southwest flow increases Saturday night ahead
of the next system which will allow us to warm up above freezing
across the forecast area on Sunday. Weak isentropic lift should also
lead to increasing high and mid-level clouds during the day. The GFS
and ECMWF are coming into better agreement on the Sunday night and
Monday system, but timing is still slightly different. Precipitation
increases from the west on Sunday night with likely PoPs over the
entire area by Monday and Monday afternoon. The GFS is quicker with
precipitation ending for most areas by Monday night, but the ECMWF
is slower and deeper with the upper-low and hangs onto precipitation
longer. Regardless, should still see at least some lingering
precipitation across the higher elevations on Monday night with
northwest post-frontal winds and orographic lift. On Tuesday into
the middle of the week, the model solutions diverge greatly with the
0z GFS showing another trough diving across the Eastern CONUS and
the 0z ECMWF showing ridging building across the Southeast with
warmer and above normal temperatures. Current forecast has been a
blend of both, but there is definitely a lot of uncertainty on the
exact evolution of systems and the overall pattern toward the middle
of next week.
