.KEY MESSAGES...
1) A cooler post-frontal airmass and northeast flow will lead
to a drop in temperatures over the weekend

2) Next chance of appreciable rain comes mid to late next week
with a low pressure system moving out of the Deep South.

Marine: A cold front will bring a surge of northeasterly SCA
winds and seas through this evening.

.DISCUSSION...
KEY MESSAGE 1...A cold front has just cleared the Crystal Coast
early this morning and will continue to push south of ENC
through the day. In the wake of this front, a cooler northeast
flow will support noticeably lower temperatures compared to what
we saw yesterday. Over the weekend, highs will be in the upper
60s to near 70 degrees. Along the Outer Banks, highs may
struggle to reach the mid-60s. Away from bodies of water, lows
should fall into the 40s tonight thanks to a drier airmass and
lighter winds. High pressure won`t be directly overhead, though,
and there will be a lot of high clouds streaming through, which
should prevent lows from getting as low as they otherwise
could. The same probably holds true for Sunday night as well.

KEY MESSAGE 2...An amplified upper level trough is forecast to
move into the Central U.S. early next week, but that is where
confidence begins to drop. By the middle to latter half of next
week, medium range guidance varies drastically with the
evolution of the upper trough as it shifts towards the Eastern
U.S. Most guidance point towards at least a piece of the upper
trough getting cutoff from the flow, but where that cutoff
occurs, and if it occurs at all, is a big question mark.
Meanwhile, for comparison, AI guidance suggests a more
progressive and less amplified evolution of the trough as it
reaches the East Coast, with less cutoff potential.

While the upper level differences equate to much different
sensible weather outcomes, the general theme appears to a
pattern that favors a period of southerly flow with milder
temperatures, increasing moisture, and the potential for showers
and thunderstorms. The forecast is very much subject to change
during this timeframe, though, so stay tuned.

.AVIATION /06Z SATURDAY THROUGH WEDNESDAY/...
Forecast confidence is high over the next 24 hours.

A cold front will continue to move south through all of ENC
over the next few hours, and should be offshore by 09z/Saturday.
A brief "thump" of gusty winds and LLWS impacts is expected
along the front, and continuing for about 1-2 hours after the
front has moved through. Winds may lower for a bit around
sunrise, then become gusty again by mid-morning Saturday. Just
ahead of the front, light winds and a moist boundary layer will
support reduced VIS in MIFG. Once the front moves through, VFR
conditions are expected to prevail. A drier airmass moving in
should limit the MIFG/BR/FG risk Saturday night, despite
weakening winds.

Outlook: The northeast flow across the area this weekend will
transition to an easterly flow as we move into early next week.
Increasing moisture within this flow appears supportive of low
CIGs and the potential for BR/FG development (not unlike what
was experienced the past few days locally). Some SHRA will be
possible as well, especially for coastal terminals (KEWN, KMRH).
Of note, confidence is lower regarding the potential for low
CIGs and SHRA during this time, but it`s worth mentioning the
potential.

.MARINE...
A cold front is moving through the central and southern waters
early this morning. Behind the front, obs show winds have
quickly increased to 15-25kt, and seas are at 3-4 ft and
building. While the strongest winds are likely to accompany the
front this morning, persistent, moderate northeast winds should
lead to seas building to 4-7 ft for most coastal waters. The
one exception is for the sheltered nearshore waters south of
Cape Lookout where seas will top out in the 3-4 foot range. The
gradient is forecast to relax some by Sunday. However, a re-
tightening of the gradient may occur south of Ocracoke Inlet,
and 25kt winds may last further into the weekend there than
currently advertised. For now, the Small Craft Advisories remain
unchanged, but some extension in time may be needed for those
above-mentioned southern waters.

Outlook: Northeast flow is expected to last through at least
Tuesday, along with elevated seas. By the middle of next week,
the pattern is forecast to begin changing, and this should
eventually least to an east to southeast flow developing for a
change. Guidance is mixed on whether or not a period of stronger
east to southeast winds will develop or not mid next week. For
now the forecast reflects sub-25kt winds mid to late next week,
but the forecast is subject to change, so stay tuned.
