.SYNOPSIS...
High pressure will build through Wednesday leading to a warming
trend. A passing dry cold front Wednesday night will usher in
the coolest air since Spring. The late week period will feature
another warmup until the next cold front arrives Sunday night
with cooler and drier weather returning to start the work week.

&&

.UPDATE...
No changes with the 7 AM EDT update. Routine aviation discussion
has been updated with the 12Z TAFs.

&&

.NEAR TERM /THROUGH TONIGHT/...
High pressure continues to build southward out of the Great Lakes.
Other than some low clouds near the coast this morning, skies should
be clear for most of the day as dry air deepens. A dry cold front
will push through the region tonight. Northerly winds around 10-15
mph today will increase briefly with the front tonight. Highs in the
mid to upper 70s today as thicknesses increase ahead of the front
and just east of a ridge over the south central US. Lows tonight in
the mid 50s behind the front. Winds overnight around 5-10 mph.

&&

.SHORT TERM /THURSDAY THROUGH FRIDAY NIGHT/...
Key Messages/Highlights:
*Rain Chances: none
*Temps: below normal

Confidence:
*High regarding dry weather; Moderate to High regarding temps

Details: No major changes from the previous forecast. Dry conditions
are expected with high pressure prevailing, sliding southeast and
overhead Fri night. We currently have Thu night as the coldest night
with lows generally in the mid 40s inland, with just a tad warmer
temps Fri night. However, temps could get lower both nights
depending on wind speeds/cloud cover, especially in the normally
colder inland spots. Would not be surprised to see a few temps get
into the upper 30s.

&&

.LONG TERM /SATURDAY THROUGH TUESDAY/...
Key Messages/Highlights:
*Rain Chances: none, except low late Sun/Sun night
*Temps: near to below normal, warmest on Sun

Confidence:
*Mostly High, except Low to Moderate regarding rain amounts
Sun/Sun night

Details: No significant changes to the previous forecast. Will start
changing air masses Saturday as high pressure shifts offshore
bringing warmer/moister conditions to the region, especially on
Sun ahead of a cold front. Some showers are possible later Sun
west of I-95 and then across the entire area Sun night before
cooler/drier weather returns Mon. Not expecting significant
rainfall or thunder chances at this time, although confidence is
lower here due to some uncertainty regarding the strength of
this system.

&&

.AVIATION /10Z WEDNESDAY THROUGH SUNDAY/...
MVFR CIGs continue to hang over eastern NC and the OBX this
morning. While there will be a gradual shift westward, any
flight restrictions should only impact ILM. By late morning,
MVFR CIGs along the southeastern NC coast will begin to erode.
Gusts up to 20 knots will be possible this afternoon under clear
skies. VFR expected throughout the remainder of the period.

Extended Outlook... VFR expected through the remainder of the
week.

&&

.MARINE...
Through Tonight... High pressure maintains northerly winds today.
Wind will gust up to 15-20 knots this afternoon. A dry cold front
will move southward across the region tonight, providing a brief
surge in wind gusts and seas. Conditions are expected to remain sub-
advisory, but seas could approach 6 feet for a couple of hours
(primarily in the NC nearshore waters). The surge will gradually
decrease into Thursday.

Thursday through Sunday...Moderate to high confidence through the
period. High pressure from the north will prevail through Fri night
before shifting offshore this weekend. Elevated winds/seas will
continue near Small Craft Advisory levels at times into Thu due to
cooler/drier air moving into the area, especially in the NC
waters.
