.DISCUSSION...
KEY MESSAGE 1...After the second day in a row that the KMHX
sounding broke a record high PW, some lingering coastal showers
tonight will be shunted off the coast by early Monday as cool
front pushes through. In the wake of the front, a reinforcing
front from the north brings breezy nerly winds that usher in dry
and seasonably cool weather. Mo cloudy to ovc skies on Mon will
keep temps on the cooler side, with highs in the low/mid 70s
despite dry weather ensuing. The reinforcing front Mon night
will bring a much drier airmass in and clearing skies, and as
high pres builds Tue into Wed, very pleasant mild and dry days
with highs near climo in the 75-80 range (low 70s OBX), but
cooler than normal lows well down into the 50s for the mainland,
and perhaps a few 40s for the normally cooler sheltered locales
as strong radiational cooling is maximized Wed morning.

KEY MESSAGE 2...Atms moderates Thu into the weekend as zonal
flow ensues, and this will bring a warming trend back to ENC,
WIth several days of warming, eventually upper level flow
becomes swrly, and a return of Gulf moisture on tap by Fri or
the beginning of the weekend. Timing in synoptic features
becomes less certain this far out, so introduced only chc pops
attm for the extended period.

.AVIATION /00Z MONDAY THROUGH FRIDAY/...
The front has pushed offshore with plenty of low level moisture
bringing widespread IFR stratus across rtes early this evening.
Only the immediate coast is reporting MVFR but expect cigs to
lower here soon. IFR/LIFR conditions expected to prevail
overnight into Monday morning. A drier airmass will begin to
build in Monday afternoon allowing cigs to lift to MVFR through
the afternoon and eventually scatter out late afternoon across
western rtes bringing a return of VFR conditions. Eastern rtes
expected to become VFR early to mid evening.

Outlook (Mon night through Fri): Winds will become
northeasterly behind a reinforcing front Mon night, surge
peaking TUE morning, though this will also usher in dry air and
hence a return to mainly VFR conditions, both day and night with
lowered dewpoints.

&&

.MARINE...
Wind fcst cont to trend down, though enough of a signal for SCA
winds/seas south of Oregon Inlet, so have issued a SCA for these
zones where probs for SCA conditions are greatest. Winds more
marginal for Pamlico sound and nrn waters, so have left out of
headlines, with just ocnl gusts to 25 kt poss. Seas of 2-4 ft
cont through Mon, then build to 5-7 ft south of OR Inlet Mon
evening, eventually subsiding back below 6 ft by late Tue
afternoon.

Outlook: Northeasterly flow of 10-15kt expected mid week as high
pres will be anchored to the north, and winds/seas remain below
SCA thresholds.
