806 pm edt Sun jul 22 2018

Synopsis
A moist southerly flow, coupled with a low pressure trough
aloft over the tennessee valley and southeast u.S., will result
in an unsettled pattern through at least the middle of next
week.

Near term until 6 am Monday morning
As of 400 pm edt Sunday...

with the heavy rainfall moving through the peninsula at this
time, and the potential for additional rainfall along the
boundary, have opted to expand the flash flood watch to include
the peninsula this evening. Otherwise, radar and surface obs
suggest that a bay breeze type boundary has set up just west of
the bay this afternoon. Expect the storms to ride up and along
this boundary this evening. With the precipitable water values
above 2.0 inches combined with potential training of echos, see
no reason to make any other changes to the watch. Some
indications that the heaviest rain may stay out of caroline and
hanover, but given the cells south of richmond, have opted to
keep them in for now. The evening shift can certainly cancel
early if need be.

Otherwise, expect showers and isolated storms to continue
across the east overnight as the upper trough starts to become
negative helping to allow for deep unidirectional flow out of
the south. This will continue through Monday, although the
precipitation will likely back to the west Monday afternoon as
the trough to the west becomes even more negatively tilted due
to another short wave moving around the trough. As such, have
maintained likely pops across the east for the entire night
tonight, and went with categorical across much of the area for
Monday.

Short term 6 am Monday morning through Tuesday night
As of 415 pm edt Sunday...

the wet and unsettled weather continues through Wednesday as
the trough over the ohio valley stays nearly stationary allowing
for continued deep and moist southerly flow. Will maintain
likely pops or greater through the period as there is really no
period where rain is more likely than another. Given the lack of
significant low level focus, it does not seem like there is a
significant flooding threat, but as the week GOES on, the more
saturated the ground will become so the potential for flash
flooding will become greater simply due to the water not being
able to soak into the ground. Wednesday may be the best day for
any heavy rainfall given that the upper trough will finally move
eastward helping to allow for better upper forcing.

It will be very humid through the period, but not terribly
warm. Highs generally in the low-mid 80s. Lows in the 70s.

Long term Wednesday through Sunday
As of 400 pm edt Sunday...

after two days of fairly good consensus between models, the
most recent 12z GFS euro runs have diverged in their solutions
days 5-7 and beyond. Thursday will start off wet, especially in
the northern neck and delmarva. The GFS initiates afternoon
convection across much of the area, especially along and west of
i-95 on Thursday... While the euro lingers a low-end rain chance
along and east of i-95. Went with a gfs-favored solution to
begin the day, but trended more towards the euro Thursday night
by tapering chance pops eastward along east of the i-95
corridor. Friday, the best opportunity for rain will be across
extreme SE va NE nc, with more isolated convection further
northwest. Saturday will feature scattered afternoon storms
across much of the area, with action waning after sunset once
again. Sunday has the potential of being the most unsettled day
of next weekend, with consistent signals in the models of a
developing low pressure over the ohio valley. This will send a
modest impulse of mid-upper level energy eastward into our area,
sparking thunderstorms across the piedmont that move towards
the coast during the afternoon and evening hours.

Ensembles indicate the potential for a continued pattern of
troughiness wet weather across much of the mid-atlantic through at
least the beginning of next week. The typical "oven-baked" july
temperatures that we can experience this time of year will not be an
issue for now... As 850mb remain a consistent 16-18 degc. In other
words, afternoon 2m temps will remain in the upper 80s around 90
degf for thurs-sun, so no extreme heat to worry about. Overnight
lows in the low to mid 70s carry us into the start of the next work
week.

Aviation 00z Monday through Friday
As of 730 pm edt Sunday...

a rather unsettled period of weather will continue through
Monday as a deep upper trough remains in place. Broad southerly
flow will allow for showers and thunderstorms especially at
phf orf ecg with brief ifr conditions.VFR to MVFR conditions
will prevail through the overnight as moist southerly flow
continues to bring periods of showers and tstms to the region.

Unsettled weather continues through Wednesday. Expect occasional
MVFR conditions at all sites through the period with some brief
ifr in heavier showers storms. Some improvement possible late in
the week.

Marine
As of 330 pm edt Sunday...

latest analysis shows sfc low pressure and an upr-level trough
stationed off to the west, allowing for deep S SE flow over the fa.

Will continue inherited headlines with this forecast package... Sca's
over the bay and ocean, which have been extended through the 4th
period with not much pattern change expected through mid week. For
now left out the rivers and sound as it looks quite marginal, but
will monitor for potential SCA issuance there as well. Winds mainly
15-25 kt over the bay ocean, with 3-5 ft waves over the bay and seas
up to 6-8 ft over the ocean. Again, the pattern persists through
midweek with a sse wind of at least 10-20kt continuing along with
seas remaining AOB 5ft. Scas conditions are likely to be extended in
future updates for portions of the marine area, ESP over the ocean.

Tides coastal flooding
As of 330 pm edt Sunday...

similar setup as yesterday, with minor flooding likely during the
higher astronomical tide tonight, primarily along the bay side of
the lwr md ERN shore and the tidal potomac and bay adjacent to the
nrn neck.

A high risk of rip currents will continue through Mon for the nrn
beaches, with a moderate risk for the SRN beaches today increasing to
a high risk for mon. Dangerous shorebreak also continues.

Equipment
As of 320 pm edt Saturday...

kdox radar is inoperable due to a failure of the motor. All
parts will not arrive until Tuesday july 24. Return to service
is unknown at this time.
