.WHAT HAS CHANGED...
Cold weather advisories were canceled earlier this morning as
temperatures and wind chills risen above criteria levels.

The Winter Storm Warning remains in effect through 7 AM Monday.

Forecast snow amounts have decreased while ice accumulations have
increased once again across the southern sections. This is in
response of warm air aloft switching precipitation from snow to
rain, freezing rain and sleet over these areas. However, snow and
wintry mix precipitation still within warning criteria. Despite
shifting precipitation totals, moderate to major travel and
infrastructure impacts are still expected to occur.

.DISCUSSION...
KEY MESSAGE 1...

Temperatures and wind chills across northern WV and southeast OH
have risen above advisory criteria. However, it will remain cold
with lows tonight ranging from the teens into the single digits.


KEY MESSAGE 2...

As a winter storm commences this afternoon and evening, the onset of
precipitation may fall as light snow. Then, strong southwest flow
aloft brings strong WAA, switching precipitation into a mix of snow,
sleet, and freezing rain mainly in the southeast half of the
forecast area, while snow continues to the northwest.

Stronger WAA occurs tonight into Sunday afternoon, transitioning
precipitation to plain rain across extreme southwest VA, central
and southern WV. Although these areas may receive rain, freezing
rain will persist in typical cold spots. Then, strong CAA takes
place Sunday night behind a cold front, switching all precipitation
back to snow Sunday night into Monday morning.

Chances of seeing 4 inches of snow or more reach 100 percent across
SE OH and northern WV, ranging from 60 to 70 percent across the
southern coalfields. Chances of greater than 6 inches of snow range
from 95 percent across SE OH, extreme northern WV, and the WV
northeast mountains. Chances for seeing greater than 8 inches range
from 77 percent across northern SE OH and the northeast WV higher
elevations.

The probability of ice accumulations greater than 0.25 inches runs
65 to 80 percent across southwest VA, extending north along the
central and northern mountains, and tapering to 17 percent at the
Charleston Metropolitan area. The probability of seeing 0.50 inches
of ice is 40 percent and continues over southwest VA and extreme
southwest WV.

Therefore, the Winter Storm Warning is now in effect until 7 AM
Monday. Although precipitation should diminish in coverage on
Monday, upslope snow could persist along the mountains into the
night.

In addition, as warm air transitions precipitation to plain
rain across southwest VA and southern WV, accumulations have
increased to near 2 inches. This rainfall amounts may produce
raises of streams and creeks across these areas by Sunday night
into Monday morning. This poses a low threat for minor flooding
during this period.

While QPF remains the same, snow amounts have once again decreased,
and ice amounts have increased over most of the area. Regardless
of shifting precipitation amounts, this system is still expected
to cause widespread power outages and moderate to major impacts
to travel and infrastructure.

KEY MESSAGE 3...

In the wake of a weekend winter storm, strong CAA takes place
with H850 temperatures reaching the minus 15 celsius. This cold
air, combined with clearing skies expected Monday night and
Tuesday, will likely produce temperatures around zero across the
lowlands, and even colder across the northeast mountains.
Pressure gradient remains tight behind the storm producing
strong gusty winds Monday. These winds and temperatures could
produce wind chill values around 10 below zero across the
lowlands, ranging to around 20 below zero across the northeast
mountains. Therefore, Extreme Cold Warnings and Cold Weather
Advisories may be required Monday night into Tuesday morning.

We will not see temperatures rise above freezing through next week
and possibly not until sometime the following week. Overnight lows
will be in the single digits and even below zero at times each
night. This could be a serious situation for folks that experience
prolonged power outages due to the winter storm this weekend. This
will also cause rivers, creeks and streams to freeze up posing the
potential for water outages for those communities that draw water
from these water bodies. Please plan accordingly.

KEY MESSAGE 4...

A clipper system and cold front provide another opportunity for
light snow accumulations, particularly in and near the mountains,
Wednesday into Thursday. The arrival of this system is also expected
to bolster the cold air mass already entrenched over the region
through next weekend.

&&

.AVIATION /18Z SATURDAY THROUGH THURSDAY/...
Widespread VFR conditions are anticipated over most sites during the
afternoon hours. Conditions will gradually deteriorate later this
afternoon and evening, when precipitation starts reaching the ground
in the form of snow. However, WAA from the southwest will allow snow
to mix with rain, sleet and/or freezing rain later tonight into
Sunday.

Much colder airmass filters in behind the cold front Sunday night
to transition any precipitation into all snow through Monday.

Expect visibility and ceilings to drop into IFR/LIFR under moderate
snowfall. Outside snowfall, MVFR/IFR conditions may persist under a
wintry mix tonight into Sunday.

Light to moderate winds are expected through the majority of the
period, with gusts to around 25 kts possible along the
mountains tonight. Northeast winds should also shift to a more
easterly direction by the end of the TAF period.
