.DISCUSSION...
As of 145 AM Tuesday...

KEY MESSAGE 1... Unseasonably warm and dry through much of the work
week, with record highs possible on Wednesday and perhaps Thursday.

An upper level ridge will strengthen and shift ewd through the week,
with the ridge centered over the Southeast US by Thursday. Surface
high pressure will generally sit over the Southeast US through the
week. Meanwhile, a trough will strengthen over the mid-Atlantic/NC
as low pressure tracks ewd from the Great Lakes to the Canadian
Maritimes through Wednesday. A backdoor front may approach central
NC from the northeast Wed night/Thu as Canadian high pressure trails
the aforementioned low, but still appears will stay generally north
of the NC/VA border. The front should quickly lift away from the
area as a rapidly deepening area of low pressure moves across the OH
Valley and Northeast Thu night/Fri. 12Z low-level thicknesses today
should be in the 1390-1400 dam range, increasing into the 1400-1410
dam range on Wed and Thu and possibly Fri. These thickness values
will support highs in the mid 80s today, increasing to mid 80s to
low 90s on Wed (about 15-20 degrees above normal), which would
threaten/break record highs on Wednesday.

KEY MESSAGE 2... A strong cold front will sweep across the area
Friday with a significant cooldown for the weekend and the potential
for some patchy frost.

A potent nrn stream s/w aloft tracking ewd across wrn and cntl
Canada Wed/Wed night will drop sewd across Ontario and the Great
Lakes Thu and Fri, deepening the trough over the ern US as it
interacts with another s/w ejecting enewd from the cntl Rockies. The
trough will continue to deepen as it moves ewd across the region and
offshore Fri/Fri night. At the surface, a rapidly deepening area of
low pressure will lift newd across the OH Valley and Northeast Thu
night/Fri, the trailing cold front moving across central NC late
Fri/Fri night. The medium-range guidance still varies wrt precip
chances with the fropa, the EC being the wetter solution but
trending drier. The pressure gradient will be quite stout Fri/Sat as
the low rapidly deepens near New England and strong ~1035 mb high
pressure builds in from the west. The low-level jet is also expected
to strengthen over the area Fri eve. Expect strong, gusty winds with
and behind the front Fri aft through Fri night. The high may weaken
ever so slightly as it builds ewd across the mid-MS and OH Valley
regions, before settling over the mid-Atlantic Sat night/Sun and
offshore by Mon.

By Saturday, highs will be similar to the lows from Thu night
(generally low to mid 60s), while lows may drop some 10-15 degrees
from Fri morn to Sat morn. However, the more significant drop in
temps will come Sat night, as the high settles over the mid-
Atlantic, when lows may drop into the mid/upr 30s across the nrn
Piedmont and upper 30s to mid 40s elsewhere across cntl NC. Some
patchy frost will be possible should the mid 30s lows be realized.

.AVIATION /11Z TUESDAY THROUGH SATURDAY/...
As of 700 AM Tuesday...

Shallow radiation fog/mist at RWI will disperse through ~13Z. High
pressure will otherwise build across cntl NC and favor VFR
conditions and light, generally wswly winds today, after calm this
morning. Redevelopment of fog/mist will be possible at RWI and
perhaps FAY Wed morning.

Outlook: Influence from high pressure over the Southeast will favor
mainly VFR conditions over cntl NC for most of the upcoming week. An
area of IFR-MVFR ceilings will develop behind a backdoor cold front
and across VA and nrn NC Thu-Thu night, though the exact location of
the front and post-frontal ceilings remains somewhat uncertain.
Associated restrictions will nonetheless be possible over cntl NC
Thu night. A powerful cold front and sharply colder air will
overspread cntl NC late Fri and Fri night, during which time a
period of strong nwly surface winds may gust between 30-40 kts.
