PREV DISCUSSION... /Issued 625 AM EST Tue Dec 11 2018/

SHORT TERM /Today through Wednesday/...

Clearing skies and moderating temperatures today as the complex
system that has plagued the region over the past several days
finally exits. Still looking at a chance for some patchy black ice
early this morning, generally from the northern and western Atlanta
suburbs northward. Temperatures have been a bit slow to fall outside
of the far north/northwest, but should dip to around or below
freezing north of the I-85 corridor. Patchy fog early this morning
is expected to diminish quickly as well, mainly by or soon after sun-
up.

Otherwise, dry with seasonal temperatures through Wednesday as the
upper flow transitions quickly from northwesterly today to
southwesterly tomorrow ahead of the next trough digging into the
center of the country.

LONG TERM /Wednesday Night through Monday/...

The next major trough deepening into the southwest will begin to
affect our area at the start of the long term. The latest model
runs have been a bit slower on bringing moisture back and it looks
as if any rain may hold off until after sunrise Thursday. So...no
mention of winter precipitation for Wednesday night. Best rainfall
chances still on track for Thursday night into Friday night. Rain
should be diminishing Saturday as the closed upper low pulls
northeast into the southern Appalachians. A mention of
thunderstorms still looks okay for Friday ahead of the surface
low. ECMWF still slower and farther south with the upper low for
Sunday with the possibility of a few lingering showers. However
for now have continued with the drier solution with no mention of
pops Sunday through Monday.
