.SYNOPSIS...
Low pressure will depart farther out to sea today with high
pressure building back into the region before sliding offshore
early this week. A front will move through mid-week with a
second front expected late this coming week and weekend.

&&

.NEAR TERM /THROUGH MONDAY/...
As of 12 PM Sunday...High pressure is building in from the west
and supplying plenty of sunshine across ENC. Light winds are
out of the northwest and with slightly below normal high temps
expected this afternoon. Most of the CWA will max out in the
upper 40s to low 50s with the NOBX being the coolest in the mid
40s.

Tonight, mid and high clouds will increase as a mid-level shortwave
moves across the area. Winds will be light to calm, and temps will
drop to around 30 (upper 30s to near 40 along the OBX). Although
guidance is not showing it, a moistened boundary layer and calm
winds will open the door for shallow fog to develop late
tonight/early Monday.

&&

.SHORT TERM /MONDAY NIGHT THROUGH 6 PM MONDAY/...
As of 12 PM Sunday...High pressure will move overhead tomorrow
morning, which will kick off the new week with clear skies and
light winds. As the high moves offshore through the day, cloud
cover will increase and winds will veer from east to southwest.
Highs will be about 10 degrees warmer than today with most of
the area reaching the upper 50s to low 60s (low 50s NOBX).

&&

.LONG TERM /MONDAY NIGHT THROUGH SUNDAY/...
As of 12 PM Sunday...

Tuesday through Wednesday...Gradually strengthening southwesterly
flow will prevail through mid-week. Temperatures will climb in
response to this WAA regime, with highs increasing to the upper-60s
Tuesday and around 70 Wednesday (low 60s OBX). A weak low traveling
along a coastal trough could produce some light showers along the
OBX on Tuesday, but no more than a few hundredths is expected at
this time.

Thursday through Sunday...A dry cold front will push across ENC late
Wednesday as a shortwave trough swings quickly across the mid-
Atlantic. This front is then expected to lift back north as a warm
front on Friday before another frontal system pushes through the
region over the weekend. PoPs remain at slight chance to chance
during this period with the greatest PoPs currently stretching
from Saturday to Saturday night (30-40%). A much cooler airmass
will take over behind this FROPA, knocking highs back down to
the 50s.

&&

.AVIATION /00Z MONDAY THROUGH FRIDAY/...
As of 700 PM Sun...Pred VFR conditions expected through the
period as high pressure centered over the mid-Atlantic expands
over the coastal Carolinas. Clear skies through this evening
will see increasing mid and high clouds overnight and Monday as
weak embedded shortwave in northwesterly flow traverses the
Appalachians. Light/calm winds and sct high clouds tonight will
allow for good radiational cooling conditions but guidance
keeps prob for fog quite low with most guidance showing less
than 20 percent chance.

Outlook: Pred VFR conditions are expected over the next few
days as high pressure builds in. A brief period of sub-VFR
conditions possible Tuesday.

.MARINE...
As of 12 PM Sunday...

Key Messages...

 - Improving boating conditions today

 - Another round of SCA conditions will be possible starting
   late Tuesday and lasting through early Wednesday amidst
   strengthening southwesterly flow

High pressure is moving in from the west and improving marine
conditions. Latest obs show 15-20 kt northerly winds and 4-5 ft
seas. Diamond is the only buoy holding on to 6 ft as of this update,
so the SCA for the central waters remains in place until 7 PM
tonight but may be able to be dropped early. Tomorrow, light
winds will veer from NE to SW through the day and seas will be
2-3 ft. Southwest flow will strengthen through the day on
Tuesday, ramping up to 20-25 kt with gusts to 25-30 kt across
the coastal waters south of Oregon Inlet Tuesday night. Seas
will build through the day as well and are expected to peak
Tuesday night at 4-7 ft south of Oregon Inlet (4-5 ft to the
north).

Winds and seas will relax early Wednesday ahead of a dry cold
front that will move across the area late Wednesday into
Thursday. This FROPA will veer the winds from southwesterly on
Wednesday to northeasterly by Thursday morning and then back to
the southwest Friday-Saturday.
