.DISCUSSION...
As of 315 AM EDT Tuesday...

KEY MESSAGE 1...Rain is expected to become more widespread today as
a front lingers across the area.

Early morning surface analysis shows a broad area of high pressure
over Ontario, Canada extending outwards into New England and
portions of the Mid-Atlantic. The cold front that passed through our
area today is currently draped across central and southern NC. Low
cloud cover persists across the CWA with showers moving along the
northern boundary across northern VA and portions of the MD Eastern
Shore. Rain is expected to become more widespread later this morning
as the front lifts back north. Exact coverage and timing of the
rain has a slightly lower confidence, but today will have the
best rain chances of the last few days. Some isolated
thunderstorms can`t be totally ruled out for the southern half
of the area, which could lead to heavy downpours and localized
flash flooding. A couple of efficient storms along the NC/VA
border into NE NC last evening produced 2-3" of rain in a short
period, which even caused over a foot of rise on the Cashie
River in Windsor. Expect the same efficient rainfall makers to
be possible again today. WPC has a Slight Risk of Excessive
Rainfall for the southeast half of the CWA, excluding the SE VA
and NE NC coast.

Additionally, northeast winds will increase later this morning as
the Canadian high pressure shifts east and low pressure forms off
the NC/SC coast. Locations along the coast, including the entire
Eastern Shore, Norfolk, Hampton Roads, and into Currituck County
will see wind gusts upwards of 25-30mph by this afternoon. The
Atlantic coast of the Eastern Shore including Ocean City and
Chincoteague will see their gusts build to 40-45mph overnight. These
higher gusts will persist for the coastline through Thursday night.
Further inland, gusts to ~20mph are expected starting this
afternoon. High temperatures will be noticeably cooler for most of
the area today as the cooler airmass works its way in from the
north. High temperatures will range from the upper 60s across the
north to the lower 80s along the south. Lows tonight will dip into
the upper 50s for our western counties, with upper 60s for the
southeast.


KEY MESSAGE 2...Strong onshore flow, cooler temperatures, and
rainy conditions will continue on Wednesday. Rain chances
gradually shift east Thursday, potentially making for a dry end
to the week. Gusty winds will persist.

Cold air damming will overtake the area on Wednesday as high
pressure remains parked to our north. This will make for our coolest
day of the week as high temperatures top out in the low to mid 60s
for the western and northern inland areas, with low 70s for the SE
half of the CWA. Inland gusts to 20mph are forecast through the
day. Winds for coastal counties will persistently be blowing
around 20-25mph with gusts to 35+mph. The strongest winds will
continue to be along the Atlantic coast with gusts to 40-45mph
expanding down the span of our coastline through the day on
Wednesday. These winds are forecast to stick around through
Thursday night as the tightened pressure gradient between the
strong high pressure to the north and the strengthening low
pressure over the ocean remains. This persistent onshore flow
will create really rough beach conditions, as high surf/wave
heights and beach erosion are likely. Wednesday will also be
when moderate to locally major coastal flooding starts, so if
you live in a coastal zone, please read our tidal flooding
section below and stay tuned to the latest forecasts. With the
CAD wedge in place, the environment will be stable leading to
steady stratiform rain across the area. While it won`t have the
higher intensity rates of a thunderstorm (since we will be too
capped for those), the persistent rainfall could still create
some flooding concerns. Lows will cool off a few more degrees
Wednesday night with low to mid 50s inland and low 60s east.

Rain chances then look to become more confined to eastern portions
of the area Thursday into the first part of Friday as a secondary
surface low forms along our coast and causes the main low to deepen,
as well as finally have the potential to gain some forward momentum.
Models disagree on exactly where the low will be on Friday,
with the GFS moving it off to the northeast while the ECMWF
keeps it closer to our shore. One solution will allow for winds
to subside later Friday and drier air to move in for the
weekend, while the other keeps the elevated impactful conditions
lingering a bit longer. For now, went with rain chances ending
Friday making way for a mostly dry weekend. Winds will likely
shift to be more N/NW overnight Thursday into Friday. This will
allow speeds to subside a bit, but gusts to 25-30mph may still
be possible into the weekend.

Highs on Thursday will still be well below normal as the
effects of the CAD remain, with lower 60s forecast west of I-95
and upper 60s to lower 70s to the east. Thursday night will be
rather chilly with some far northwestern and western cool spots
potentially dipping into the upper 40s. If the low is able to
shift to the northeast, our winds will turn northerly Friday, as
mentioned above, giving another chance for more of the area to
see lows in the lower 50s (likely everyone except the coast).
Highs will begin to moderate back into the lower 70s Friday into
the weekend.


KEY MESSAGE 3...Widespread moderate to locally major tidal flooding
(inundation of 2-3 feet AGL in vulnerable areas) is likely by the
Wednesday afternoon/evening high tide due to strong northeast winds.
Tidal flooding is expected to continue for several tide cycles
given the persistent northeast winds.

Northeast winds increase to 20-25 kt today with strong NE winds
likely from tonight through Thursday night. This will will cause
water levels to rise across much of the area (especially along the
bay, tidal rivers, and Atlantic coast). Widespread minor tidal
flooding is expected by this evening/tonight`s high tide. Ramp up
Coastal Flood Advisories have been issued for much of the area
(except the bay side of the MD Eastern Shore) from later today
through the start time of the Coastal Flood Watch (Wed morning-
evening depending on zone). A significant rise in tidal anomalies is
forecast on Wednesday. Moderate tidal flooding could begin along the
upper James and tidal Rappahannock/Potomac rivers by Wed AM, with
widespread moderate to locally major flooding forecast during the
Wednesday evening high tide. Moderate to locally major flooding is
expected to continue through at least the Thursday evening/night
high tide. Coastal FLood Watches remain in effect for a large
majority of the tidal area beginning Wednesday evening for most and
Wednesday morning for tidal southern Potomac, Rappahannock, and
upper James rivers. While it is a bit too early for Coastal Flood
Warnings, expect the watches to be upgraded to warnings with later
forecast packages. While water levels should gradually fall Friday-
Saturday as winds diminish a bit and become NNW, minor to moderate
tidal flooding seems likely through at least Friday evening and
possibly longer.

.AVIATION /12Z TUESDAY THROUGH SATURDAY/...
As of 630 AM EDT Tuesday...

MVFR conditions persist across most of the area this morning.
CIGs are generally BKN-OVC015, though there are some pockets of
IFR, particularly at SBY. Guidance indicates that IFR will
likely develop at RIC after ~12Z as well. NE winds are 6-8kt
currently, but will become 12-17kt with gusts up to ~25kt for
eastern terminals after 14Z. RIC could see some gusts to
18-20kt this afternoon as well. These gusty winds and mix of
IFR CIGs to the north and MVFR to the south will continue
through the TAF period. Confidence in exact SHRA coverage
through the day today is low, but guidance has high enough
chances to include as prevailing groups for now. Did push back
RA timing for southern terminals until this afternoon. Slightly
higher confidence exists at RIC where the better RA chances
will be today. Regardless, VIS restrictions from the RA/BR are
expected.

Outlook: An unsettled pattern is expected to persist through
most of the upcoming week. Wed should continue to see widespread
flight restrictions, with at least intermittent degraded flight
conditions likely through Thursday. Coastal terminals will also
have elevated NE winds for an extended period, with winds
remaining elevated and shifting to the N-NW Fri-Sat.

.MARINE...
As of 315 AM EDT Tuesday...

Key Messages:

- SCA level winds are forecast today with east to northeast winds
increasing to 20 to 25 kt by the afternoon. Ramp up SCAs have been
issued for all marine zones that are under Gale Warnings.

- Confidence in a period of gales with NE winds remains very high
from tonight-Thursday/Thursday night. Gale Watches have been
upgraded to Gale Warnings for the ocean, bay, Lower James River, and
Currituck Sound. High-end SCAs have been issued for the upper
rivers.

- Seas build to 10-14+ feet, likely leading to dangerous marine
conditions.

Early morning wx analysis shows that the actual cold front is to the
south of the waters, with E-NE winds of 10-20 kt (highest north) and
3-6 ft seas. While the front is to our south, the strongest CAA will
take some time to reach the marine area. Conditions start to
deteriorate today with E-NE winds increasing to 20-25 kt by late in
the day. While guidance has come down by a knot or two with respect
to wind, there really is not a whole lot of change in forecast
thinking given the setup (impressive sfc high to our north/CAA over
warm waters). While a few gale force gusts are possible north of
Parramore Island by early evening, the first surge of stronger CAA
arrives tonight as the 1035-1040mb builds across eastern Canada and
low pressure begins to gradually deepen a couple hundred miles
offshore of the VA/NC coast.

Rapidly deteriorating marine conditions are expected across the bay
and ocean overnight, with winds increasing to ~30 kt by Wed AM with
gusts to 40 kt. Gale Watches have been upgraded to Gale Warnings for
the bay, ocean, and lower James River. High-end SCAs have been
issued for the upper rivers starting this evening-tonight (where a
few gusts to 35 kt are possible but confidence was not high enough
to go w/ Gale Warnings). The pressure gradient tightens further on
Wed/Wed night as a stronger CAA surge arrives. Winds are forecast to
remain around 30 kt with gusts 40 kt on Wed, with the strongest
winds still expected Wednesday night through Thursday as the
strongest CAA arrives. 925mb winds are progged to increase to 40-45
kt during this time. With the unstable marine boundary layer and
water temps in the mid to upper 70s, wind gusts at that level should
easily be able to mix down to the sfc. Therefore, confidence is
fairly high that we will see a period of sustained gale force winds
with gusts to 45 kt across the ocean and lower bay during the Wed
evening-Thu timeframe. Will continue to mention gusts as high as 45
kt in the MWW/CWF. which would lead to a period of sustained gale
force winds with gusts to 45 kt. Gale Warnings run through Thursday
evening for the upper bay, part of Thu night for the lower bay/lower
James, Friday morning for the ocean, and Friday afternoon for the
offshore (20-60nm) coastal waters. There is decent consensus in the
global models that winds become more northerly and diminish to 20-25
kt on the bay/Lower James Thursday night and to just below gale
criteria 0-20nm offshore Friday morning. While low pressure is
progged to rapidly deepen well offshore Friday-Saturday,
model/ensemble consensus shows it far enough away from the coast
that gale gusts would be confined to the 20-60nm offshore zones
after Friday morning. Winds gradually turn to the NNW by Fri
night/Sat AM. Local wind probs for 34+ kt gusts remain near 100%
through Thu, but drop to below 10% on the bay by early Fri AM, and
fall to 10-20% out to 20nm by late Friday morning. Therefore, did
not expand Gale Warnings too far out in time (except for the 20-60nm
zone). Nevertheless, will still have to monitor the rapidly
deepening offshore low Fri/Sat, and forecast changes are possible if
it looks like it will deepen closer to the coast. Given the
prolonged strong NE winds, seas are forecast to build to 10-14+ ft.
This will likely lead to dangerous marine conditions from late
Tuesday night through Thursday night.

Dangerous surfing conditions are likely by late today and will
continue through Thu with the prolonged onshore flow, and remain
high into the weekend due to elevated seas even as the winds become
NNW. Localized beach/dune erosion is possible from mid to late week
as well. High Surf Advisories have been issued for all beaches
starting late today and continuing through early Thursday evening
for now.
