.DISCUSSION...
As of 305 AM EDT Sunday...

KEY MESSAGE 1...Light to moderate morning rain still expected.
There is a Slight Risk (level 2/5) for severe weather with afternoon
thunderstorms. A few brief tornadoes and strong wind possible.

Early morning sfc analysis indicates the remnant sfc low from Isaias
and the attending UL low situated over TN and a warm front extending
east from it into the Carolinas. This warm front is forecast to lift
north into the local FA this morning, then the low will cross from
SW VA toward the Eastern Shore during the afternoon. High pressure
ridging off the New England coast is ridging down the mountains,
forming a subtle CAD feature over the western piedmont and
Appalachia. Latest radar shows light to occasionally moderate rain
across much of the area and is most widespread around the Richmond
metro and the northwestern counties. Winds are gusty at the coast
ahead of the aforementioned features with gusts up to 30mph already
observed. High-res guidance does still indicate that rain should
fill in across the area, becoming moderate to locally heavy at times
as the warm front pushes into the area. Once this batch of rain
lifts north, there should be a break in the rain for the middle
portion of the day. A second round of precip will then cross through
the area SW to NE as the low passes through. Total QPF from both
rounds of rain looks to be quite a bit lower than was guidance
depicted several day ago, partially due to the dry slot that was not
originally shown. Based on radar trends so far and latest runs of
the HREF/REFS, total QPF will likely only be 0.5" to 1" at most for
much of the area. Areas along the immediate coast in NC/Virginia
Beach and far western areas in Louisa/Fluvanna could see closer to
1.5". Probs for 2" have dropped to ~20% for these areas with <10%
for the rest of the area.

The second round of rain this afternoon is where the severe weather
risk comes in. CAMs depict a broken line and/or supercells
progressing from SW to NE during the late afternoon as the sfc low
trek NE and the UL trough pivots into the region. A moist and
unstable airmass will advect into the area behind the warm front.
00z guidance suggests MLCAPE will climb into the 1000-1200 J/kg
range which is more than enough to support convective activity. Deep
layer shear of 40kt+ along with low level shear of 30kt+ and long,
curved hodographs further supports the threat. Add to that SRH
values over 200, low LCLs, and SE sfc winds and you`ve got yourself
a decent set up for a few tornadoes and damaging wind gusts. The SPC
outlook for today is mostly unchanged from yesterday with a slight
risk for interior portions of the FA and a Marginal Risk along the
coast. Highest confidence is south of I-64 since CAD may dampen
instability across the north and northwest.

Showers and thunderstorms from this second round should taper off by
8pm. Additional showers on the backside of the low will be possible
late tonight into early Monday, primarily north of I-64 and on the
Eastern Shore.


KEY MESSAGE 2...A brief warmup is expected early next week with
cooler temperatures later in the week.

An upper level ridge centered across the central CONUS
gradually builds into the region through the week. Meanwhile,
surface high pressure remains centered across the Deep South
through midweek before a second area of high pressure builds in
from the north late in the week. This will bring a warmup with
highs in the 70s for most Mon, lower 80s for most Tue (mid-
upper 70s across the Eastern Shore), and mid 80s for most Wed
(upper 70s to near 80F for the Eastern Shore). Temps gradually
cool late in the week but remain at or above average through
Fri. Otherwise, mainly dry conditions are expected from Mon-
Thu.

KEY MESSAGE 3...Coastal Flood Advisories continue for portions of
east-central VA along the Bay and tidal Rappahannock/Potomac for
minor flooding today. Coastal Flood Statements continue for Hampton
Roads, the tidal York/James, and the bayside of the lower Maryland
and VA eastern shore for nuisance flooding. A high Surf Advisory has
been issued for all coastal zone for ~8 ft nearshore waves.

A rapid rise in water levels is expected with the high tide cycle
today, occurring mainly in the morning for the lower Chesapeake Bay,
lower James, and during the afternoon farther north across the
middle Peninsula/northern Neck and late afternoon into early evening
for the lower Maryland eastern shore Bay zones. Given the E-SE wind
direction, the highest impacts are expected across areas in the
Advisory (east central VA along the tidal Rappahannock/Potomac and
west shore of the Bay. This should be just one tide cycle with the
fast moving nature of this system and winds becoming S-SW later this
afternoon and tonight.

.AVIATION /12Z SUNDAY THROUGH THURSDAY/...
As of 650 AM EDT Sunday...

The 12z/11 TAF period will be unsettled as a warm front lifts
across the area this morning and sfc low pressure passes through
this afternoon. IFR is spreading across the terminals with MVFR
hanging on another hour or two at SBY. Light rain should
continue to spread across the FA as well as lowering CIGs as the
front presses north. A break in precip is forecast around mid-
day, but CIGs are expected to stay in IFR range. A second round
of showers and thunderstorms will then pass through the area SW
to NE as the sfc low traverses from SW to NE as well. Conditions
are expected to improve tonight into Monday morning. ESE winds
will be gusty through this afternoon, especially at the coast.
Winds turn to the S then SW this evening.

Outlook: Dry conditions expected after sunrise on Mon. VFR
conditions prevail through mid week.

.MARINE...
As of 325 AM EDT Sunday...

Key Messages:

- Gale Warnings and Small Craft Advisories in effect this
  morning as the remnants of Isaias track through the TN Valley
  and towards the local area, with strong high pressure well
  off the east coast.

- A cold front crosses the waters on Monday with increasing NW
  winds. SCA conditions are likely in the Chesapeake Bay.

Surface analysis shows Isaias` remnant low over TN with 1032mb high
pressure centered east of Cape Cod. A tight pressure gradient is
noted across the Mid-Atlantic with easterly winds 20-25 kt with
gusts 30-35 kt. Waves in the bay are 2-4 ft with 3-5 ft near the
mouth. Seas offshore are building rapidly from S to N. Buoys off the
northern OBX are showing 6-9 ft seas with 3-5 ft seas north of of
Cape Charles.

Gale Warnings and strong Small Craft Advisories remain in effect for
all area waters this morning. Latest guidance and local wind probs
have continued to trend downward with respect to both the magnitude
and duration of gale conditions ahead of and along a northward
lifting warm front this morning. Observations off the NC coast do
show some gusts ~35 kt so far this morning and these winds will lift
northward into the local coastal waters over the next 6-9 hours.
Gale conditions will to be fairly brief at any particular location,
with the strongest winds likely to accompany the lifting warm
front`s passage. Thereafter, winds will become SE and fall below
gale thresholds. SCAs will replace gales from S to N as the
strongest winds lift northward through the morning hours. SCA
conditions continue in the sound/rivers until early afternoon and in
the Ches Bay through early evening, though headlines in the bay
could be cancelled prior to expiration with current model trends
showing rapidly diminishing winds this afternoon. Waves in the bay
will continue to build to 3-5 ft (5-7 ft at the mouth) this morning
before falling to 2-3 ft (3-4 ft mouth) this afternoon. 6-9 ft seas
nearshore and 7-11 ft well offshore will lift northward with the
stronger winds this morning. Have expanded the High Surf Advisory to
include all coastal zones given current observations. Seas will
slowly diminish this afternoon into tonight but are expected to
remain above the 5 ft SCA threshold well into Monday.

A cold front is forecast to cross the waters in the wake of the
departing system Monday morning. Another period of SCA conditions is
likely for the bay through early afternoon as cooler and drier air
filters into the region. Mainly sub-SCA conditions Mon night through
midweek. Another front likely crosses the waters late Wed into Thurs
with increasing N and NE winds. Long range models are starting
to key in on a much stronger frontal passage next weekend.
