.WHAT HAS CHANGED...
No changes were made to the Cold Wx Advisory at this issuance,
though temperatures and wind chills have been updated. A Special

to highlight widespread black ice and hazardous road conditions
this morning.

Updated aviation discussion for 00z TAFs.

.KEY MESSAGES...
1. Very cold temperatures this morning. A Cold Weather
Advisory is in effect for much of the area thru 9 AM, with a
risk of hypothermia and/or frostbite if precautions are not
taken. Widespread black ice is also expected thru the morning
where roads have frozen over due to snowmelt on Sunday, causing
hazardous road conditions.
2. Temperatures gradually warm thru the first half of the
week. Precipitation chances return late Tuesday and linger into

.DISCUSSION...
Key message 1: Very cold temperatures this morning. A Cold Weather
Advisory is in effect for much of the area thru 9 AM, with a risk of
hypothermia and/or frostbite if precautions are not taken.
Widespread black ice is also expected thru the morning where roads
have frozen over due to snowmelt on Sunday, causing hazardous road
conditions.

Ridge of high pressure extends thru the Deep South and Ohio Valley
from anticyclone near the Louisiana coast, with slightly confluent
northwesterly upper level flow upstream of trough off the East
Coast. On the periphery of the ridge, a modest sfc/upper pressure
gradient persists over the southern Appalachians. This morning, wind
chills will remain largely below -5F in the mountains east/northeast
of Asheville, and mostly 0 to 5 in the lower elevation areas east of
I-26. Cold Weather Advisory remains in effect for those portions of
the CWA through 9 AM. Wear appropriate clothing, a hat, and gloves
when venturing out this morning. Ensure portable heaters are used
correctly. Do not use generators or grills inside.

Temps are below freezing throughout the area this morning leading to
black ice where roads hadn`t dried on Sunday. Temperatures are not
expected to warm above freezing until noonish in the Piedmont and
mountain valleys, though some higher elevation areas will remain
below freezing through the day. Sunny skies likely will lead to more
melting/drying over the course of the day. However, for at least the
morning, be extremely careful due to the potential for black ice on
roads, parking lots, sidewalks, driveways, bridges, and overpasses.
A Special Weather Statement was issued to highlight this possibility
across the CWA. If traveling, be prepared for hazardous road
conditions, especially on bridges and overpasses as well as on
untreated roadways. Use extra caution when walking on sidewalks,
driveways, and in parking lots. Temperatures are not expected to be
as cold tonight, with warmer and more humid air beginning to return
to the region ahead of an approaching weak low pressure system.
Nevertheless patchy black ice could remain a problem tonight into
early Tuesday.


Key message 2: Temperatures gradually warm thru the first half of
the week. Precipitation chances return late Tuesday and linger
into Thursday with mostly dry conditions expected for the remain-
der of the week.

Flat upper ridging will be translating across the Ohio Valley and
the Appalachians by Tuesday morning while upper shortwave energy
dives down the eastern flank of a tall west coast upper ridge. This
will carve out a positively tilted upper trof over the Southern
Plains with a broad zone of mid/upper level SW flow extending from
the Gulf states into the Carolinas. At the same time, a sfc cold
front will drop SE across the Midwest and into the Ohio Valley/TN
with a broad area of precipitation ahead of the bndy. The leading
edge of the precipitation is expected to reach the NC mtns late
Tuesday evening where rain chances are the highest. The latest
guidance continues to struggle to maintain much precip coverage
east of the mtns due to the upper trof orientation, lack of any
stronger forcing, and a poorly-developed sfc low. The latest gui-
dance hasn`t changed much wrt temperatures late Tuesday thru early
Thursday, with most ensembles members not quite cold enough for
wintry precip east of the mtns. Nonetheless, I still have a low-
end chance for a rain/snow mix east of the mtns but no real accu-
mulations. Any snow accumulations in the mtns are still expected
to be below Advisory criteria. Beginning Thurs afternoon, things
look mostly dry for the rest of the week and thru the weekend.

.AVIATION /12Z MONDAY THROUGH FRIDAY/...
At KCLT and elsewhere: Dry and VFR through Tuesday morning. All
sites except KAVL pick up from the SW by mid-morning; KAVL remains
light NW. Winds become light and variable overnight. A few cirrus
will drift in this morning with some stratocu or altocu also seen
during the day over the TAF terminals; some MVFR level clouds could
bank along the TN/NC border tonight but not likely affecting KAVL or
other TAF sites.

Outlook: Dry and VFR through at least midday Tuesday. A cold
front brings precipitation and possibly periodic restrictions back
Tuesday night into late Wednesday. Brisk winds and some rain or
light snow chances may return to the mountains late Friday.
