Synopsis for the coastal waters from sandy hook nj to fenwick island de and for delaware bay.. Tropical low pressure just west of the appalachians will lift to the northeast through the mid-atlantic and northeast this morning, and then a cold front will move across the region this afternoon. Surface high pressure builds into the midwest as an upper trough digs into the eastern great lakes and northeast tonight through Sunday. A weak cold front is expected to move through the region Monday night through Tuesday.

Synopsis
A cold front over the midwest states will move through the
region on Saturday. Meanwhile, remnant tropical moisture will
stream northeastward ahead of the front. High pressure builds in
from the great plains and midwest region for the second half of
the weekend. A weak cold front is expected to move through the
region Monday night or Tuesday. High pressure returns to the
area for the middle of next week before moving off the coast
late in the week.

Near term until 6 am Saturday morning
Contemplated and discussed a flash flood watch for the predawn
hours. In the end, we decided to hold off. Yes, pws associated
with a remnant tropical storm are in excess of 2.00 inches, but
we feel the speed of the heavier cells and lack of a significant
predawn convective contribution diminishes the threat to a
certain degree. In addition, FFG is fairly high. We feel the
hours between 09z and 12z will see the heaviest rains. We are
still expecting downpours, but they will be isolated and moving.

We have highlighted in the hwo.

Previous discussion...

severe thunderstorm watch 369 is in effect until 10 pm.

Previous discussion...

not many changes from the previous forecast. We still expect to
see scattered showers and thunderstorms to move into our region
from the west over the next several hours. Any clearing this
afternoon has been mostly self-destructive as cumulus fields
have developed quickly when there has been any clearing (except
over DELMARVA - where a stronger cap is in place). As a result,
we are slightly cooler than previously expected at the surface.

However, still warm enough for ml CAPE values above 500 j kg
across our region. In addition, a favorable wind profile with
increasing amounts of 0-6 km shear (primarily speed shear, as
flow above 900 mb is nearly unidirectional). Thus, there remains
a marginal to slight risk for severe storms over our region
through the evening hours.

Once we get to late this evening, we should see a brief lull as the
short wave trough weakens and the boundary layer stabilizes. After
midnight though, the cold front is expected to approach the region
from the west, and just ahead of this front, we should see one more
round of showers and thunderstorms. By tonight, the threat shifts
from strong winds to heavy downpours. However, the progressive
nature of the front should limit any flooding threat.

Short term 6 am Saturday morning through 6 pm Saturday
The biggest difference with the latest model runs was how much
faster most models bring the front through the area, with many
models showing it clearing the coast by 12z. I'm not sure it will
move through that quickly, but did trend faster. This has not only
implications for how quickly we dry out (likely should see dry
conditions across the region by late morning), but also in the wind
forecast and with the MAX temperature forecast (chose to go closer
to the cooler operational models than the MOS guidance).

Long term Saturday night through Friday
The large-scale pattern over the CONUS will feature an upper trough
east of the rockies and an upstream ridge through early next week.

For our area, this pattern will 1) allow for a break in the active
stretch of weather we have had recently and 2) keep us far away from
the heart of the summer heat (western conus).

A cold front will slowly approach from the northwest Monday before
moving through the forecast area sometime either Monday night or
Tuesday morning. Meanwhile, a series of shortwave disturbances
rounding the base of great lakes upper trough may provide a source
of deeper lift for showers both days. The bulk of the forcing for
ascent looks to remain upstream of our area on Monday, so it is
likely that any diurnally-driven convection will be sparse in
coverage and confined to the higher terrain N W of the fall line.

There is no mention of thunder in the forecast for Monday as
soundings from both the NAM and GFS do not indicate a favorable
environment for sustained deep convection owing to limited moisture
availability and a residual capping inversion in place. Despite a
post-frontal regime, the setup may be slightly more conducive for
low-topped thunderstorms on Tuesday as a cold pool aloft that is
associated with the upper trough shifts overhead and helps steepen
the mid-level lapse rates.

Mainly dry conditions are expected Tuesday night-Thursday with high
pressure influencing our weather. Showers and storms return to the
forecast next Friday as high pressure shifting offshore and the next
low pressure system approaches from the west. Kept pops low (20-30
percent) for Friday given the considerable model disagreement on d7.

Temperatures will be slightly below normal and quite comfortable for
outdoor activity with highs for most of the area in upper 70s and
lower 80s (except mid 80s on Sunday across the i-95 corridor, east)
through the middle of next week. Temperatures gradually return to
near normal late in the week as the high moves off the coast and
southerly return flow develops.

Aviation 02z Saturday through Wednesday
The following discussion is for kphl, kpne, kttn, kabe, krdg, kilg,
kmiv, kacy and surrounding areas.

MVFR and even brief ifr conditions will be possible with any showers
and thunderstorms that may move over the TAF sites. The primary
period for showers and thunderstorms will be first through 03z, and
then again between 08 and 12z (possibly going as late as 15z for the
coastal sites including kacy and kmiv).

Otherwise, mostlyVFR conditions are expected with skies clearing
after 15z.

Breezy southwesterly winds, with gusts up to 20 kt will be possible
through about 00z. An abrupt wind shift, winds shifting from
southwesterly to northwesterly, is expected with a cold front
moving over the area generally between 10 and 15z.

Outlook...

Saturday night through Monday morning...VFR. Winds primarily out of
the W or nw.

Monday afternoon through Tuesday... MostVFR but sub-vfr restrictions
still a possibility, especially on Tuesday in locally heavier
showers.

Tuesday night and Wednesday...VFR.

Marine
The SCA for de bay has been allowed to expire.

Previous discussion...

sca conditions, for both winds and seas are expected to continue
tonight and tomorrow. An abrupt wind shift from southwesterly to
northwesterly winds is expected by mid day Saturday. Winds may
diminish a bit behind the front, but seas are expected to remain
elevated through much of the day.

Outlook...

Saturday night... Did not extend the current SCA into Saturday night
with seas likely to drop below 5 ft in our coastal atlantic waters.

W-sw winds around 10 kt early in the evening shift to NW behind a
cold front.

Sunday through Wednesday... Winds and seas are expected to remain
below SCA criteria. An isolated TSTM possible on Tuesday.

Rip currents...

a moderate risk for the formation of dangerous rip currents
continues today for the nj shore. For tomorrow, winds will be
shifting off shore, but a 5 to 6 ft swell may lead to a moderate
risk for the formation of dangerous rip currents especially
along the central and southern nj shore. For the northern nj
shore and the delaware beaches, the risk is expected to be low
at this time. However, even with a low risk... The bigger diurnal
difference in the tide cycle due to the new moon today could
mean some rapidly changing conditions.

Tides coastal flooding
Very high astronomical tides will continue through the next few days
in association with the new moon today. However, flow should be
shifting more offshore, so though spotty minor tidal flooding
is possible with this afternoon evening's high tide, the threat
for widespread minor tidal flooding has diminished.

Phi watches warnings advisories
Pa... None.

Nj... None.

De... None.

Md... None.

Marine... Small craft advisory until 6 pm edt Saturday for anz450>455.
