AREA FORECAST DISCUSSION
National Weather Service Raleigh NC
1015 PM EST Wed Jan 27 2021

.SYNOPSIS...
Surface low pressure over near Charlotte this evening will track
northeast across North Carolina tonight and then off the coast. Cold
high pressure will build into the region from the north on Thursday
and persist through Saturday. Another storm system will cross the
region early Sunday through Monday.

&&

.NEAR TERM /THROUGH TONIGHT/...
As of 1000 PM Wednesday...

The forecast appears to be coming along just about as expected.

The latest data analysis indicated the core of the mid level trough
was advancing eastward over KY and northern TN at mid-evening, with
the core of the upper jet extending from the TN valley region east
across northern GA - advancing ENE over NC. Low pressure had
developed at the surface (1012 mb) over upstate SC. Very modified
cool and dry advection courtesy of a high pressure well to our north
continued to advance from central VA into north-central NC. However,
even this air mass was still too warm to support wintery
precipitation. Surface wet bulbs were in the lower to mid 40s, with
upper 30s advecting into Person, Vance, Granville (northern tier of
NC) counties. That alone would not be enough cold air.

However, strong cooling aloft was advancing SE from eastern KY/WVA
through SW Virginia, with rain changing to snow noted as far south
and east as the Blue Ridge of VA (Galax, Hillsville, Wytheville).

Of note, it was so warm today (50s) that even after several hours of
rainfall and cooling, it was still 35 at Boone with rain at 900 PM.
On a positive side for snow lovers, Jefferson just turned to snow at
the last observation.

As this dynamic system crosses the Mountains in the next few hours,
the rain will overspread all of the region. The rain/snow line
should continue to advance from the Mountains into the NW Piedmont
around or shortly after midnight. Then, the process of heavy
precipitation rates and rapid cooling aloft will allow this
transition to occur through the overnight into the Triad, Triangle,
and the Coastal Plain. Even the Sandhills should have a brief change
to snow very late tonight.

Satellite and radar data continue to show the advancement of the
shield of heavier precipitation rates over north-central NC between
12 and 4 am, then shift east into the NE-E portions between 4-7 am.
Snow banding appears likely with some heavy rates within a couple of
the bands expected. As precipitation continues to move expect
temperatures to cool rapidly as precipitation rates increase. The
warm boundary layer being up so high in is a concern for the
transition. This could mean that surface cooling rates will take a
little bit longer and result in transition to be delayed slightly.
As of 03z, temps are just about where they were expected to be at
this stage of the event, with possibly a bit of a lag in the colder
air arrival in the NC Northern Mountains. The most recent sounding
(00z) from GSO reported a freezing level of about 4700 ft, this is
cooler than the RAP model suggests which is a good sign that it is
infact cooling a tad quicker.

Due to the warm conditions today, the rain to start the event, and
the wetness of the snow (with temps dynamically cooling into the
lower 30s with the heavy rates well after midnight, we still expect
to have 1-2 inches of wet snow, with locally higher totals of 3+
inches possible from the Triangle to RWI and Roanoke Rapids. This is
just about the exact forecast as the previous one, with little
change in that previous thinking.

&&

.SHORT TERM /6 AM THURSDAY MORNING THROUGH THURSDAY NIGHT/...
As of 350 PM Wednesday...

The surface low and upper trough will be moving away from the
region on Thursday and Thursday night resulting in cold and dry
conditions. Any lingering snow showers or flurries across the
Coastal Plain at daybreak will move way by mid morning with
mainly sunny skies expected by late morning. Highs will only
range in the mid 30s to lower 40s. It will be very cold with
lows between 15 and 25 on Thursday night. -Blaes
&&

.LONG TERM /FRIDAY THROUGH WEDNESDAY/...
As of 250 PM Wednesday...

The period will start with shortwave ridging aloft and a ridge of
high pressure at the surface extending south from the upper Great
Lakes.  Low level thicknesses are progged to be in the 1285-1295m
range, which should result in morning lows in the upper teens and
lower 20s...although some high clouds spilling over the upper
ridging could impact lows Saturday morning...with highs int he mid
40s.

Sat night through Monday... the atmospheric river producing trough
along the west coast today will swing east through the central US
and then across the Mid-Atlantic States/Southeast, with models
indicating a Miller B low moving up the coast Sunday/Sunday night.
The GFS remains a slightly faster, weaker and warmer solution
compared to the ECWMF.  Wintry precip will be a concern given the
intrusion of arctic air preceding the system, although the parent
high is forecast to be sub-1040mb and a bit far to the north of the
preferred location for optimal cold air supply.  The forecast
pattern suggests some wintry precip at onset, with a changeover for
most of the CWA, followed by some wrap around moisture in the
ECWMF's deeper upper low on Monday. Will keep snow mention confined
to the climatological region in the NW Piedmont.

The middle of next week appears to be dry with ridging in the wake
of the aforementioned system, though models indicate height falls
again over the central US and another low pressure system
encroaching on the eastern US by the end of the week.  Temps should
start out slightly below normal and trend to or above normal as the
week wears on.

&&

.AVIATION /00Z THURSDAY THROUGH MONDAY/...
As of 809 PM Wednesday...

The rapidly approaching mid level trough will induce a surface low
pressure development offshore later tonight and early Thursday. Rain
has already overspread the Mountains, with the rain/snow line still
located in SE KY. VFR CIGS will lower to IFR and LIFR conditions
with rain developing from the west this evening, spreading into the
KFAY and KRWI areas around 05-06z.

Initially, the precipitation will be all rain before changing
to a mix of rain and snow across the north at around 06Z and then to
all wet snow for a short time before ending from west to east
between 09 and 12Z. The precipitation will largely be rain across
the south with a short period of an hour or two of mixed rain and
snow. Conditions will improve notably after 12Z with VFR by 15-18z.

Looking beyond Thursday PM, VFR conditions with fair weather is
expected Thursday afternoon into Saturday evening. Another storm
system will bring a threat of adverse aviation conditions to the
area late Saturday and continue into Sunday with some improvement on
Monday.
