Synopsis for the coastal waters from sandy hook nj to fenwick island de and for delaware bay.. A cold front will continue to push to our south overnight, then high pressure builds to our north Monday and Monday night. This high builds offshore to or northeast on early Tuesday, while a frontal boundary lifts across our area. This front may stall through Wednesday while a couple of low pressure systems move eastward along the boundary. This front lifts to our north Wednesday night, before a couple of cold front move across the area later Thursday into Friday.

Synopsis
A cold front will cross our region overnight, then high pressure
builds to our north Monday and Monday night. This high builds
offshore early Tuesday, while a warm front lifts across our area.

This front may stall through Wednesday while a couple of low
pressure systems move eastward along it. This front then lifts to
our north Wednesday night, before a couple of cold front move across
the area later Thursday into Friday.

Near term until 6 am Monday morning
The coverage of convection has struggled likely due to quite a bit
of dry air aloft and deep westerly flow. There is enough instability
and the low-level lapse rates have steepened, however the overall
forcing looks to be on the weaker side despite strong shear
(unidirectional flow). A remnant MCV looks to have been responsible
for the convection now getting ready to exit the northern areas,
with mostly isolated development so far to its west on a leftover
boundary. Looks like the better chance of some more widespread
showers and thunderstorms is later this evening with convection
currently across west virginia and western pennsylvania, and this
may become more focused across our southern zones (md de
especially). There remains uncertainty though on the evolution of
the convection, and given not much coverage thus far the enhanced
wording was removed.

Any stronger convective cores that are sustained will have the
potential to produce locally strong to damaging winds especially
given still some dry air aloft leading to downburst wind potential.

Some hail is possible, however severe hail would be limited to any
isolated robust sustained core. The severe threat looks to be mostly
for far southeastern pa, southern nj and md and de.

Drier air should start to filter in behind the cold front late this
evening and especially overnight, leading to clearing conditions.

Depending on how quickly the front arrives, temperatures could drop
into the 50s, but more likely, low level moisture will keep
temperatures from dropping below 60 for much of the area.

Short term 6 am Monday morning through 6 pm Monday
Memorial day should be a pleasant day for much of the region.

The only possible exception is portions of delmarva. If the
front stalls over this area, showers and storms could linger in
delmarva through the day. Although there is still some
uncertainty, so I stayed close to the previous forecast, it is
worth noting that some of the 12z models show this front
clearing much further south, leaving the entire region dry.

Temperatures behind the front will be 5 to 10 degrees lower
than Sunday, with highs mostly in the 70s and lower 80s. Despite
the northwesterly flow, a sea breeze could develop later in the
day, cooling coastal areas further.

Long term Monday night through Sunday
An unsettle pattern continues for much of the upcoming week
into the weekend, with several rounds of showers and
thunderstorms.

Monday night will start out fairly quiet as high pressure
builds to our north. Very late in the night, the high pressure
begins to lose any grip it has on our area as a frontal boundary
begins to lift northward, and as a short wave vorticity impulse
moves into the area, scattered showers and thunderstorms may
develop late Monday night into early Tuesday morning.

As we go into Tuesday, the front lifting toward the area is
forecast to slow down and may stall out across the region later
Tuesday, into Tuesday night, and into Wednesday as well as
several waves of low pressure move along the boundary. As
multiple rounds of short waves vorticity impulses aloft move
across the area within the northwest-west flow aloft, showers
and thunderstorms will continue in the forecast Tuesday-
Wednesday, although it will not rain the entire time. The higher
probabilities will be tied to the passages of the short waves.

As we move into Wednesday night, the frontal boundary is
expected to lift to our north, and precipitation chances will
lower through Wednesday night, although not be zero as there
will remain unsettled conditions with an additional short
wave vorticity impulse affect the area.

On Thursday and Friday, a couple of frontal boundaries are
forecast to move across the area. The front on Thursday
currently looks to be the stronger of the two, and has a better
chance of showers and thunderstorms to be associated with it.

Thursday also has higher pw values at 1.5-2.0 for some areas, so
it will have a higher threat for heavy rainfall, although pw
values remain over an inch into Friday.

Dry weather may return for early Saturday as high pressure
briefly builds across the northeast and into our area. However,
showers may begin to develop during the afternoon as return flow
develops and a short wave moves across the area. Also, another
cold front is currently forecast to move toward the area on
Sunday, which could bring another round of showers and
thunderstorms to the area.

Temperatures through most of the extended period are forecast
to be above normal, with Tuesday possibly being the coolest day
and below or near normal.

Aviation 22z Sunday through Friday
The following discussion is for kphl, kpne, kttn, kabe, krdg, kilg,
kmiv, kacy and surrounding areas.

Tonight... Some showers and thunderstorms around through about
midnight, however coverage and timing is less certain. Local and
brief MVFR ifr conditions (especially visibility) will occur with
any heavier shower or thunderstorm along with gusty winds.

Otherwise,VFR. West or southwest winds near 10 knots, locally
northerly near thunderstorms, becoming all light northerly overnight.

Monday...VFR. North winds 5-10 knots, becoming locally southwest
later in the afternoon. A sea breeze at acy and perhaps miv will
result in an east to southeast wind.

Outlook...

Monday night... GenerallyVFR condition expected, although
clouds increase and lower late in the night with a chance of
showers. Winds become northeast 5-10 knots overnight.

Tuesday-Tuesday night... MVFR ceilings may develop early Tuesday
as a warm front lifts across the area and continue into the
night. Chance of showers and thunderstorms during the period.

East to northeast winds Tuesday and Tuesday evening, become
southeast Tuesday night.

Wednesday-Wednesday night... MVFR conditions possible early,
then lifting toVFR during the morning. Showers and
thunderstorms remain possible, especially Wednesday afternoon
and evening. Winds shift to southwest early and may gust 15-20
knots during the day.

Thursday-Thursday night... GenerallyVFR, except lower
conditions possible with showers and thunderstorms Thursday
afternoon and night. Southwest winds may gust 15-20 knots during
the day Thursday.

Friday... GenerallyVFR, except lower conditions possible with
showers and thunderstorms during the day. Southwest winds may
gust 20-25 knots during the day.

Marine
Winds and seas are expected to remain below small craft
advisory conditions through memorial day. Thunderstorms with
gusty erratic winds will be possible through this evening.

Outlook...

Monday night-Friday... Conditions expected to remain below
advisory levels through the period, although winds may gust
around 20 knots at times. There is a chance of showers and
thunderstorms each day, which could produce locally higher winds
and waves should they occur.

Rip currents...

the risk for the formation of dangerous rip currents is low
through this evening. An increasing long period swell may
increase the risk to moderate on memorial day.

Phi watches warnings advisories
Pa... None.

Nj... None.

De... None.

Md... None.

Marine... None.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
