.DISCUSSION...
As of 256 AM EDT Sunday...

KEY MESSAGE 1...An unsettled pattern prevails today through the
middle of the  week, with near average temperatures, increasingly
humid conditions, and daily chances of showers and thunderstorms.

A low pressure system is currently sliding across the Ohio River
Valley, with an associated cold front draped across the Tennessee
Valley through the South. Just to the west/southwest of the area,
showers and isolated thunderstorms have been training across the
area, bringing localized rainfall totals in some areas to 4-8".
Meanwhile across our forecast area, KAKQ radar is only detecting a
few light showers across the western piedmont. With the low to the
west, and high pressure currently offshore, moisture is slowly being
funneled into across the region. SPC mesoscale analysis still
depicts that PW across most of the AKQ FA is still 1.5" or less. A
tongue of moisture can be seen making its way up into southern VA
where the high QPE is being observed. High PW values will continue
to overspread the area today, with 2.2-2.4" forecast starting this
evening into tonight as the deep-layered S-SW flow advects rich Gulf
moisture northwards. The highest precip chances will initially be
across south-central VA during the afternoon (as the deep moisture
arrives here first). Showers and tstms should gradually spread NE
through the evening (though it may very well remain dry near the
immediate coast and on the Eastern Shore). While localized flash-
flooding is possible if storms train across train across the same
location (as seen this morning to our west), these storms will be
moving and are not expected to be stationary. With this in mind and
the fact that hi-res guidance is not honing in on a certain area,
have decided to not issue a Flood Watch for any of the area at this
time. SPC has maintained a Marginal Risk for severe storms for areas
generally west of I-95 for today, with isolated damaging wind gusts
possible. Temperatures today will be in the mid 80s across the
piedmont due to the increased cloud cover and shower/thunderstorm
development, while the remainder of the area will like reach the
upper 80s to near 90 degrees this afternoon.

Showers/tstms are likely across the area on Monday afternoon as a
lead shortwave potentially tracks over the area. Some guidance is
not quite as excited about Monday, while others still suggest that
this will be the most widespread day for convection. The trough
dampens a bit from Tuesday/Wednesday, but scattered showers and
thunderstorms are still expected during the aftn/evening on both
days as SW flow aloft weakens some and deep moisture remains nearby.
Given the environment, and relatively weak unidirectional flow aloft
and tall/skinny CAPE, there will be a threat of localized flash
flooding each day, but the severe threat should remain relatively
low with these thunderstorms due to the very saturated atmospheric
column and weak flow aloft. Days 1-3 (Sunday through Tuesday) are in
a `Marginal` ERO as the overall flash flood risk is more isolated
given a lack of a larger scale focusing mechanism, as the front
associated with the low pressure system remains north of the local
area. High temperatures dip down slightly below average during the
early week period thanks to the cloud cover and multiple rounds of
showers/tstms.

KEY MESSAGE 2...A more typical summertime pattern returns mid-late
week, with isolated to scattered afternoon showers and thunderstorms
and near to slightly above normal temperatures through the weekend.

Though not quite as unsettled as the first half of the week, the
latter half of the week will see isolated to scattered afternoon
showers and thunderstorms. With the decreased convective coverage
forecast, temperatures will return to near to slightly above normal
with highs in the upper 80s to lower 90s. Dew points will remain in
the mid to upper 70s, making for quite humid conditions. Heat
indices will approach 100 degrees for a good portion of the area
Thursday through Saturday, but due to temperatures remaining near
normal, heat headlines are not expected at this time.

.AVIATION /06Z SUNDAY THROUGH THURSDAY/...
As of 150 AM EDT Sunday...

VFR conditions currently prevail at all terminals this morning.
Winds are from the SE-S at 5-12 kt (highest along the coast), with
upper level cloud cover streaming across the area. VFR flight
conditions will continue for a majority of the TAF period, though
scattered showers and thunderstorms may bring brief periods of sub-
VFR to a few of the terminals this afternoon and evening. Winds
outside of convection will increase through the afternoon, with
gusts of 15-20 kts possible at the coastal terminals.

Outlook: Shower/tstm chances continue Sunday night and Monday as a
slow moving upper trough approaches the area, and linger into
Tuesday through Thursday. Periodic sub-VFR conditions are possible
during this time, mainly from early morning stratus, and brief vsby
restrictions in heavy rain.

.MARINE...
As of 230 AM EDT Sunday...

Key Messages:

- Southerly winds increase this afternoon into Monday. Small
  Craft Advisories have been issued for all local waters except
  the upper rivers.

- Shower and storm chances return today and continue through this
  week.

Winds are slowly diminishing early this morning with most sensors
reporting S or SSE winds of 10-15 kt. Waves in the bay are around 2
ft with seas 2-3 ft. Expect a lull in the stronger S flow to linger
through the morning before the gradient between low pressure to the
west and high pressure offshore tightens again late this afternoon
into the overnight hours. SCA headlines have been issued for all
local waters (minus the upper James, Rappahannock, and York rivers)
starting at 4PM this afternoon. S and SE winds increase to 15-20 kt
with gusts to 25 kt for the bay, sound, and lower James by mid to
late afternoon and continue in that range into at least Monday
morning. Offshore, winds increase to 15-25 kt with gusts up to 30 kt
during the same period. There remains some uncertainty as to how
long the stronger southerly flow persists on Monday, so some
extension to ongoing headlines are possible. Waves build to 2-3 ft
tonight in the Ches Bay while seas are forecast to increase to 3-5
ft S and 4-6 ft N. Seas will slowly drop off from S to N late Monday
afternoon into the evening. Sub-advisory conditions are then
expected to dominate from Tuesday through late week. Shower and
storm chances return to the area today and linger through much of
the week. While widespread severe convection appears unlikely,
locally higher winds/waves/seas will accompany the stronger
thunderstorm cores.

There is a Moderate Rip current risk at the northern beaches today
and Monday. The southern beaches may require an upgrade to moderate
risk on Monday in subsequent forecast cycles.
