Synopsis
A warm front will continue to lift through the area as high
pressure moves further offshore. A chance for rain showers and
thunderstorms returns as a cold front passes through the region
tomorrow afternoon and evening. A rather unsettled pattern
through next week as a series of disturbances travel across the
great lakes into the northeast with warm weather otherwise
prevailing.

Near term until 6 am Sunday morning
Showers and thunderstorms extended from central pennsylvania
down into west virginia around 9:30 pm. A mid level impulse
associated with the precipitation will continue to work its way
eastward, along with a surface warm front. The mid level feature
is expected to pass over our region between about midnight and
3:00 am with the warm front passing closer to dawn.

We are anticipating an increasing potential for showers and
scattered thunderstorms with most of the precipitation that
falls in our region occurring between about 11:00 pm and 4:00
am. Any linger showers and thunderstorms should be off the coast
by 5:00 am.

The mid level impulse should keep the showers and thunderstorms
somewhat intact by the time they reach our forecast area, even
with the loss of daytime heating. However, the relatively stable
conditions in our region should help to weaken the showers and
thunderstorms a bit.

A south wind around 5 to 10 mph this evening is forecast to
become southwest to west late tonight. Low temperatures are
expected to favor the 60s.

Short term 6 am Sunday morning through 6 pm Sunday
Tomorrow could be the warmest day of the year so far for much
of the area. With the warm, moist air mass in place,
temperatures near 90 will be possible for the delaware valley
and coastal plains. Further west, highs will only be a few
degrees lower in the upper 80s.

Unsurprisingly, with this airmass in place, there is a chance
for thunderstorms across the region. A trough will set up, and
remain over our region through the day. Confluence along this
trough could serve as the focus for convective initiation.

Additionally, if we do have low clouds overnight, differential
heating boundaries could develop Sunday morning as the low
clouds erode. Initially the mid levels (from 800 to 600 mb) will
be quite dry which should limit convective initiation, at least
initially. Many models are depicting little, if any, qpf,
because of a combination of the potential for a cap into late
afternoon, and the fact that there is limited synoptic scale
lift until much later when the cold front approaches. Given that
much of the lift may come with mesoscale features (which would
not be picked up by the coarser resolution models), forecast
pops are higher than most guidance, with a general 30 to 40
percent across the region.

If thunderstorms develop during the afternoon, there will be a
marginal risk for severe storms, especially in DELMARVA which
should have more unstable air in place. If any storms become
severe, the primary hazard would be damaging winds, as wind
shear in the lowest km will be too low for much of a tornado
threat, and the very warm boundary layer could limit the hail
threat.

Long term Sunday night through Saturday
Overview:
the all-too-familiar pattern continues, at least to start the
upcoming week featuring a stubborn longwave trough over the
western u.S. And a ridge across the southeast. A series of
shortwave troughs will circumnavigate the ridge to our south
over the beginning portion of the week, bringing several chances
for showers and thunderstorms. Again, placement and strength of
convection over the plains will have an influence on the exact
placement of the quasi-stationary front that looks to set itself
up over and just to the north of our cwa. In other news, warm
and humid weather looks to arrive just in time for the
unofficial start to the summer season. By Thursday, there are
signs that the pattern may begin to break as a shortwave trough
begins to amplify a developing longwave trough across eastern
canada.

Dailies:
a weak impulse moves across the region along the stalled front
on Monday, bringing the chance for some showers and
thunderstorms in the morning. Seasonable with highs near 80.

Tuesday, a stronger shortwave trough and surface low moves
along the front just to our north, thus a higher likelihood of
showers and thunderstorms. Similar temperatures to Monday.

The front remains draped across the northern half of the cwa
Wednesday, thus there is a continued chance for showers and
thunderstorms, especially for the lehigh valley, southern
poconos, and NW nj. Highs will be noticeably warmer, perhaps the
warmest this year with many places topping out near or just
above 90, with the exception of areas remaining in precipitation
across the northern portion of the cwa.

Another warm day Thursday as the front looks to remain north of
most of the area, but another shortwave trough and surface low
look to push a cold front across the great lakes and into the
mid-atlantic, thus ending our possible two-day spell in the 90s.

Another round of showers and thunderstorms will be possible as
the cold front moves through the region. There is the chance a
few of these could be on the stronger side, so will need to
monitor this as the week progresses. Highs may be a few degrees
cooler depending on cloud and precipitation coverage.

Slightly cooler weather returns to close out the week on Friday
and Saturday as the cold front moves offshore. Highs look to
sit near 80 with just a slight chance for a few scattered
showers and thunderstorms.

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

Overnight... MainlyVFR through about 03z. Showers and scattered
thunderstorms between about 03z and 08z will produce MVFR ifr
conditions at some locations. Lingering MVFR conditions are
expected after 08z. South wind around 8 to 12 knots becoming
southwest 4 to 8 knots.

Sunday... Lingering MVFR conditions through about 12z, otherwise
vfr with scattered clouds. There is a chance of afternoon
showers and thunderstorms but their timing and potential
coverage is a low confidence forecast. They will not be
mentioned in the taf. West wind increasing to 8 to 12 knots with
gusts around 20 knots.

Outlook...

Monday...VFR expected with light and variable winds trending a
northerly direction.

Tuesday... GenerallyVFR, though cig and vsby restriction
possible with showers and thunderstorms. Southerly winds 10 to
15 knots with gusts to 15 knots possible.

Wednesday... GenerallyVFR, more cig and vsby restrictions are
possible with scattered showers and thunderstorms, especially to
the north. Southwesterly winds 5 to 10 knots turning more
southerly with gusts to 15 knots possible.

Thursday...VFR with restrictions to MVFR or even ifr with
scattered showers and thunderstorms. Winds out of the southwest
5 to 10 knots, with gusts to 20 knots possible.

Marine
Winds and seas are expected to remain below small craft
advisory criteria tonight and Sunday. Southerly gusts above 20
kt are possible especially on the southern atlantic coastal
waters late tonight.

Outlook...

Monday through Wednesday... Sub SCA conditions expected with
south to southwesterly winds 10 to 15 knots. A few gusts to 20
knots possible, especially across the northern atlantic zones
Tuesday afternoon. Seas 2 to 4 feet.

Thursday... SCA conditions possible with seas 3 to 5 feet. Winds
10 to 15 knots with gusts to 18 knots possible.

Rip currents...

tomorrow.

Phi watches warnings advisories
Pa... None.

Nj... 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.
