.SYNOPSIS...
High pressure will persist over the area through Monday. A
passing cold front brings a chance for brief showers on Tuesday,
followed by dry weather Wednesday. Then a second front will bring
more widespread rain for Thanksgiving Day and much colder temps for
the end of the week.

.NEAR TERM /THROUGH TONIGHT/...
As of 215 AM EST Sunday: Flat upper ridge will build in across
the eastern US, with some cirrus spilling over the axis across the
forecast area from time to time today. But overall, sunny skies
expected with a large diurnal temp range. Lows this morning will
start out below normal, but warm to a few deg above normal for aftn
highs. Winds will be light, making for a pleasant day across the
area. The axis of sfc high pres will slide to the East Coast
tonight, allowing for a light SWLY flow to set up atop the forecast
area. It will be another good night for radiational cooling with
mostly clear skies and light wind, but lows will not be as cold as
this morning, basically near normal.

&&

.SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/...
As of 3:05 AM EST Sunday: The short-term fcst picks up at 12z
on Monday with low-amplitude upper ridging centered along the
Appalachians. Over the next 24 to 48 hrs, another upper trof
will translate over the Great Lakes from the west with the trof
axis passing just to our north on Tuesday and then lifting NE
and over the New England Coast by the end of the period early
Wednesday. At the sfc, broad high pressure will be centered
just to our SE as the period begins early Monday. Over the next
24 hrs or so, the high will get suppressed and shift further
offshore as a robust low lifts up and over the Great Lakes and
pushes a cold front thru our CWA. The front is progged to be
east/south of our fcst area by Tues afternoon with broad high
pressure spreading over the region in the front`s wake. Any QPF
associated with this system still appears minimal and it should
all be liquid. We can expect some gusty winds with the fropa on
Tues, especially over the mtns, but values should remain below
Advisory criteria.

&&

.LONG TERM /WEDNESDAY THROUGH SATURDAY/...
As of 2:55 AM EST Sunday: The extended fcst picks up at 12z on
Wednesday with more mid/upper zonal flow over the Southeast and
very broad upper trofing well to our north over SE Canada. By the
end of the week, another round of broad upper trofing is expected
over the eastern CONUS that will likely linger into the weekend.
At the sfc, transient high pressure will briefly move over our
area on Wednesday, and then offshore by early Thursday. At the
same time, another sfc low will quickly eject out of the southern
Plains and track over our area or just north of it. Most of the
latest long-range guidance continues to trend faster with this
system, and now has the low lifting NE of our fcst area by late
Thursday with another round of high pressure spreading over the
area on Friday and lingering well into the weekend. As for the
sensible fcst, Thanksgiving still looks wet with the potential
for a decent amount of QPF across most of our CWA. I did lower
PoPs earlier on Friday to reflect the faster movement of the
low. I also still have some amount of NW flow snow over the NC
mtns early Friday as temperatures have been trending lower.

.AVIATION /09Z SUNDAY THROUGH THURSDAY/...
At KCLT and elsewhere: VFR conditions will prevail at most terminals
through the TAF period, as dry high pressure settles over the
region. Winds have gone light or calm and will continue thru
mid-morning, then pick up out of the SW but remain light. Any
restrictions will be due to lake fog at KAND and KHKY around
sunrise as the air temperature cools significantly below the lake
water temperature with calm winds conducive to fog development.

Outlook: A weak cold front may bring scattered rain showers and
associated restrictions on Tuesday. Dry high pressure briefly
returns Wednesday. A more significant storm system may bring
widespread rain and restrictions on Thursday.
