.LONG TERM /THURSDAY NIGHT THROUGH SUNDAY/...
As of 130 AM EST Monday: Starting at 00Z Friday with the 500mb
pattern showing a broad trough from the Rockies to the East Coast
with a series of clipper type systems moving SE from NW Canada
toward our region. Weak high pressure will keep us dry for
Thursday night then the first clipper system arrives Friday morning.
The current run of the EC has a brief shot of snow only affecting
the northern NC mountains around 12Z Friday. The EC has this feature
lifting out quickly. The GFS has a more robust front reaching the
length of the TN and NC border in mid day Friday with some spill
over east for late day Friday across the foothills and piedmont.
Some light NW Flow snow lingers along the TN border into early
Friday night on the GFS. Medium range models have cold high pressure
passing over our area Friday night into Saturday. The next shortwave
and front increases moisture Saturday night into Sunday with a low
forming near the Gulf coast then moving across Florida. The GFS
fades out the frontal moisture as it crosses the mountains in mid
day Sunday keeping us dry through Sunday night. The EC has a much
more robust low pressure crossing northern Florida Sunday and moving
up the Carolina coast Sunday night dropping a few inches of snow on
the Piedmont Sunday night. Obviously, with varying solutions as to
what may happen next weekend we cannot place any great certainty on
any one scenario. Temperatures will be 5 to 10 degrees below normal
Friday through Sunday.
Not sure why GSP is not considering FV3??
