Area Forecast Discussion
National Weather Service Raleigh NC
1140 AM EST Tue Jan 23 2018

.SYNOPSIS...
A cold front will exit central NC early this afternoon. An area of
high pressure and attendant seasonably cool air mass will build into
and settle over the region Wednesday and Thursday.

&&

.NEAR TERM /THIS AFTERNOON/...
As of 1140 AM Tuesday...

have made adjustments to the hourly temperatures based on observed
trend and expectation of warming prior to the passage of the 850mb
trough. Appears that most of central NC will reach the 70 degree
plateau with lower 70s probable over the eastern half of central NC.
still expect strong gusty winds through early afternoon. Have seen a
few reports of gusts close to 40 mph.

1040 AM discussion...

Any adjustment to the near term forecast was to dwindle the PoP
chances across the east and increase the sfc wind gusts through
early afternoon.

Scattered-numerous showers exiting the northern coastal plain at 15Z
along a pre-frontal trough. Based on sfc dewpoints and wind field,
the sfc cold front is just entering the western Piedmont. At the
initial onset of the clearing, strong gusty winds are occurring.
Recorded wind gusts between 40 and 45 mph have occurred in the Triad
region. This is supported by the 12Z GSO sounding which depicts 35-
40kts just off the sfc. Expect this batch of strong gusty winds to
traverse east through the rest of the morning, reaching the coastal
plain counties early this afternoon.

Modest convergence along the sfc front will likely produce a band of
low topped showers over the east half of central NC through 18Z. SW
sfc flow behind the sfc front will advect a drier more stable air
mass as dewpoints drop into the 40s across the coastal plain and 30s
in the Piedmont.

The passage of the 850mb trough will not occur until late in the
afternoon. The late initiation of the cold air advection will allow
temperatures across the region to soar into the upper 60s and lower
70s, with mid 70s a good possibility over the southern coastal plain
and Sandhills.

&&

.SHORT TERM /TONIGHT/...
As of 410 AM Tuesday...

Mostly CAA-driven lows, though with brief radiational cooling
potential over the wrn Piedmont, are expected to dip into the lwr to
mid 30s for most. Skies will be mainly clear, aside from srn stream
upr jet-induced cirrus that will nose nwd across SC, and into at
least srn NC, after midnight.

&&

.LONG TERM /WEDNESDAY THROUGH TUESDAY/...
As of 145 AM Tuesday...

Wednesday through Saturday: Expect dry weather through Saturday. An
upper level shortwave and a reinforcing dry cold frontal passage is
expected Wednesday night/Thursday. Surface high pressure is expected
to build into the area in the wake of the secondary cold front and
remain over the area into Saturday. Meanwhile, the upper level ridge
will move eastward over the Carolinas through Friday night. Highs
will be generally in the upper 40s north to mid 50s south through
Wednesday and Thursday, with moderation beginning Friday. Lows in
the upper 20s to low 30s Wednesday and Thursday nights, increasing
Friday night.

Saturday Night through Tuesday: Another upper level trough and
surface cold front will develop over the Midwest and progress
eastward toward the Mid-Atlantic over the weekend. As southwesterly
flow increases, so will the warm, moist advection into the region.
As a result, cloud cover and chances for precipitation will increase
late Saturday into Sunday as the cold front approaches. Some
differences in the evolution of the upper level trough and the
timing and duration of convection as it moves into/through Central
NC have developed between the medium-range models. The ECMWF is more
amplified, slower, and wetter than the GFS. As a result of the
latest forecast cycle model differences, confidence in the timing of
the front and convection associated with it is low.

&&

.AVIATION /12Z TUESDAY THROUGH SATURDAY/...
As of 700 AM Tuesday...

Generally MVFR ceilings, with pockets of IFR ones, and MVFR
visibility restrictions in showers, will become VFR with the passage
of a lead cold front from west to east between 12-14Z at wrn sites
and 16-17Z at ern ones.

A strong swly low level jet (llj), on the order of 40-50 kts as low
as 1500-2000 ft, with progressively stronger winds above that level,
will continue to migrate newd across e-cntl and nern NC this
morning. The presence of this feature will support the continued
newd development and maintenance of the aforementioned ceilings and
convection. Since the axis of this llj is departing, low level wind
shear should be ending in the next hour or so at RDU/RWI/FAY, if it
has not already. The passage of the aforementioned cold front will
result first in the redevelopment of scattered to numerous showers
along it, then behind it with abrupt clearing, with a veering of
surface winds to swly and a similarly abrupt increase into the 15-25
kt range (sustained), with gusts up to 30-35 kts for several hours
immediately following the frontal passage. These winds will then
lessen and continue to veer to wly or nwly later this afternoon and
evening.

Outlook: MVFR ceilings will be possible Sat, with showers Sat night,
ahead of, and in association with, a weekend frontal system.
