.DISCUSSION...
KEY MESSAGE 1...NCFS has issued a burn ban statewide starting
this evening. Will reissue Inc Fire Danger statement for Sunday
for areas that get to less than 35% Min RH interior zones,
despite the light winds, as fuels are very dry due to previous
day`s windy conditions.

KEY MESSAGE 2...An anomalously strong high will build over the
Carolinas tonight, with light winds, clear skies, and a very dry
airmass supporting ideal radiational cooling conditions. This
is a classic setup for temperatures falling lower than blended
guidance, and lows tonight were trended towards the 10th-25th
percentile of available guidance. This plus probabilistic
guidance suggests a high likelihood of temperatures falling into
the low 30s for many inland locations away from bodies of
water. A few upper 20s cannot be ruled out in the typically
colder locations. Based on this, the Freeze Watch will be
upgraded to a Freeze Warning, with no change in area.
Surrounding the warning area will be the potential for patchy
frost impacts. A Frost Advisory was considered for a few
counties closer to the coast, but the patchy nature expected
suggests impacts won`t be widespread enough in those areas for a
headline.

KEY MESSAGE 3...A weak frontal boundary is forecast to approach
ENC towards the middle of next week. This front will be running
into notable ridging aloft, which makes its evolution less
certain. Synoptically, this pattern tends to favor frontal
boundaries weakening/losing support as they reach the Carolinas.
Consequently, where models tend to differ is whether or not
fronts in this pattern will stall over the area, or lift quickly
back north as a warm front. The latest suite of guidance shows
these typical differences, which makes the precipitation and
temperature forecast less certain from mid-week on. Below is a
quick breakdown of the sensible weather differences between the
two possible solutions:

SCENARIO 1: In this scenario, the front briefly stalls over ENC
in the Wednesday/Thursday timeframe, before quickly lifting
back north on Friday. This scenario would focus the highest
precipitation chances on Wednesday and Thursday, with a lowering
chance of precip by the weekend. This scenario favors much
warmer temperatures compared to SOLUTION 2 (70s/80s vs 40s/50s).

SCENARIO 2: In this scenario, the front stalls over ENC for an
extended period of time, potentially well into next weekend.
This scenario favors an extended period of overrunning
precipitation from mid-week into next weekend. This scenario
also favors cooler temperatures and a stronger cold air damming
setup. Of note, this scenario suggests highs only in the 40s and
50s on Friday.

Blended guidance currently favors scenario 1. Meanwhile,
machine learning guidance doesn`t show a clear leaning one way
or another. Stay tuned for updates as significant forecast
changes are possible in the coming days.

.AVIATION /06Z SUNDAY THROUGH THURSDAY/...
VFR conditions are expected today and through tonight with high
pressure moving offshore. As return flow develops, some moisture
advection will result in clouds along the coast, and potentially
as far inland as the US 17 corridor, but this shouldn`t effect
aviation as cloud bases remain 3500-5000 ft. Some coastal
cloudiness continues overnight, but expect the TAF sites to
remain mostly clear aside from areas of high clouds.

Outlook: Mostly VFR conditions are expected through mid week.
However, with the moist, southerly flow regime in place, there
could be early morning areas of patchy fog. Mid to late week, a
weak frontal boundary may approach the area from the north, and
this may introduce a chance of SHRA, TSRA, and sub-VFR
conditions.

.MARINE...
Update as of 4 PM Sat...Have cancelled all remaining gale
warnings as gradient winds cont to lessen, and gusty winds will
slowly diminish from n to s tonight, though high seas will
linger into Sunday on the coastal waters esp south of Oregon
Inlet.

Moderate to strong northerly winds of 15-25kt are ongoing
across all waters at this time, with some of the warmest waters
experiencing sustained winds of 25-30kt. Frequent gusts of
25-35kt have been common (higher over the warmer waters). Winds
will remain elevated for several more hours, then begin to lay
down this evening as a strong area of high pressure moves in.
Marine headlines remain in effect to cover the wind hazards
through the remainder of the day and into this evening. For the
coastal waters, 6ft+ seas are expected to last into Sunday
morning which will eventually require the Gale Warnings to be
transitioned to Small Craft Advisories once winds fall below
34kt.

Seas are currently peaking around 6-9ft (3-5ft for the areas
south of Cape Lookout protected from northeasterly swell). Seas
are forecast to gradually lay down to 4-6ft by Sunday morning,
then finally drop below 6ft by Sunday afternoon.

Outlook: More benign boating conditions are expected to kick
off next week thanks to high pressure offshore and light south
to southwest flow developing around it. Eventually, the gradient
is forecast to tighten by the middle of next week, which may
provide the next opportunity for 25kt winds.
