.WHAT HAS CHANGED...
SCAs have been issued for all coastal waters and Pamlico Sound
for Nern surge behind FROPA MON.

Patchy fog ongoing in early morning hours, threat for necessity
of a dense fog advisory appears to be diminishing however.
Conditions will continue to be monitored.

&&

.KEY MESSAGES...
1) Mostly dry and warm SUN on deck, seabreeze showers can`t be
completely ruled out.

2) A strong cold front will move through late Monday.
Widespread rain showers are expected (70-90%). Depending on the
timing of the front, scattered severe thunderstorms and heavy
rain may accompany FROPA.

3) Monday`s front lift back N as a warm front late TUE into WED
followed by another cold front THU representing the next wave
of showers and thunderstorms.

.DISCUSSION...
KEY MESSAGE 1...Your Mother`s Day forecast continues to suggest
the area remains mostly dry with subsidence aloft in the wake
yesterday`s shortwave. With that said, light background winds
and clearing skies will allow for the development of a
seabreeze. Leftover low level moisture will be enough to lead to
a diurnal cu field and the seabreeze may provide enough
convergence to lead to some light showers along the boundary.
Bulk of guidance has a dry forecast for today with a few HiRes
models showing the afternoon seabreeze shower threat. Carrying
SChc of showers and just below mentionable probability of
thunder. MaxTs in the mid 80s inland, mid to upper 70s OBX and
areas along the immediate coast cooled by the seabreeze.


KEY MESSAGE 2...Not much change in forecast thinking for now,
though we have seen some trends in the 12Z guidance. Decent
agreement on next stronger shortwave and attendant cold front
moving through the region Monday. This system could have
fairly strong dynamics with sharp-ish troughing aloft pivoting
over ECONUS to become more negatively tilted as it approaches.
Front currently forecast to enter the Nern extent of the FA
around sunrise and pushing S toward the Crystal Coast in the
afternoon. A severe thunderstorm threat is possible with this
system, with the main threats strong to potentially damaging
wind gusts, some potential for hail in strongest storms, and
heavy downpours. Instability will be maximized in the
convergence zone between the seabreeze and the cold front,
generally E of HWY17 and S of HWY70. CAPE values differ widely
between available guidance, on the order of 0.5-1.5kJ/KG with
the difference between models mainly being frontal timing.
Event total QPF has decreased for far inland and Nern zones
that are away from the greatest instability and convergence,
light showers with little vertical development early, a tenth to
a quarter of an inch. The area mentioned above could see in
excess of an inch of precip under stronger cells. SPC has
maintained a marginal threat (level 1/5) for the a similar area
as yesterday`s outlook. Should the timing of the front slow any,
would expect the outlook area to increase with more heating
providing more instability as well as greater upper level
support for storms as the troughing aloft is currently forecast
to lag behind FROPA a few hours. Stout CAA out of the N behind
the front (strongest winds over coast, 20-25kt gusts) will
bring in cool air and keep skies mostly clear into WED. Maybe
upper 40s, but most likely low 50 Mins and low 70s TUE.

KEY MESSAGE 3...A stacked low cutting across the Sern extent of
the Great Lakes and high pressure migrating offshore brings
warm and moist air across the Carolinas mid week ahead of the
next front set to cross the area around the Thursday time frame.
Will need to watch this system for severe potential as well.

.AVIATION /12Z SUNDAY THROUGH THURSDAY/...
Several observation sites across ENC have shown IFR/LIFR
conditions (mainly due to BR/FG) over the past several hours.
However, airport webcams suggest this is more of a ground fog
phenomena, and not a deep layer of impactful fog. TAF amendments
have been made to try to best convey what is ongoing, and how
VIS is expected to evolve through this morning. VFR conditions
are expected to prevail from about 12/13z onwards through the
remainder of the day. By this afternoon, a FEW/SCT CU layer may
develop along the seabreeze, along with a southerly wind shift.
The risk of TSRA along the seabreeze appears very low today.

Later tonight, low clouds may begin to increase in advance of
an approaching cold front. However, guidance differ on the time
of arrival of these low clouds. If the clouds are slower to
arrive, there may even be an opportunity for reduced VIS in
BR/FG once again.

Outlook: A cold front will sag slowly south through ENC on
Monday, bringing a chance of SHRA and TSRA and sub-VFR
conditions. A northerly wind shift will occur with the cold
front, with a period of gusty NE winds expected by Monday
afternoon. After Monday, a lower impact period for aviation
appears likely on Tuesday. The next chance of sub-VFR conditions
is then expected mid-week as the next weather system moves
through with a chance of SHRA and TSRA in the WED/THU timeframe.

.MARINE...
Best boating day this weekend today. Buoys currently show seas
3-4ft@5-7sec. These seas will subside through the day with
easing winds through the morning, generally Werly becoming light
and variable before turning Serly 5-10kt this afternoon these
easing winds will allow the 1ft@5sec wind chop out of the SSW on
top of the background swell to fall out further calming seas;
2-3ft@7-8sec out of the SE all the way out to 60+nm. Winds
become SW-W at 10-15 kts tonight. Waters inside of ~40nm
expected to remain shower and tstorm free though inland rivers
may see some seabreeze shower activity, 15-20% chance.

Outlook (Sunday night through Thursday): SWerly winds
strengthen some Sunday night into Monday ahead of next fropa
with SCA conditions becoming more likely with post frontal
northerly flow of 25+ kt MON evening and into Tuesday. SCAs
have been issued for all coastal waters and Pamlico Sound this
forecast cycle. Further expansion of SCAs to Nern rivers and
sounds remains possible, but current forecast is more marginal
over these waters currently. Gale potential has decreased some
for offshore waters overnight MON into early TUE morning, but
the threat for brief periods of gale force gusts does remain
over offshore waters S of Cape Hatteras. Winds diminish later
Tuesday into Wednesday as high pressure briefly reestablishes
itself. MON`s front lifts back N through the region mid-week
ahead of the next front to cross late WED/early THU.
