Synopsis
A nearby front will lift slowly northward into new york and new
england tonight and on Wednesday. A slow moving cold front is
forecast to approach from the northwest on Wednesday night and
Thursday. The boundary is expected to pass through our region on
Thursday night. High pressure is anticipated to follow for the
coming weekend and for the early part of next week.

Near term until 6 am Wednesday morning
The earlier convection across the lower susqu valley has
diminished for the most part with one or two surviving cells
escaping into the southern poconos attm. Other dying tstms
across DELMARVA has morphed into a large area of showers across
srn de NE md. Going forward, the models are all over the place
with the hrrr showing a dry night and the 18z NAM showing more
tstms developing after 6z. The the nearby front, it seems that
some activity should be expected, so I have just refined the
pops a bit mostly N W and adjusted for present conditions.

Patchy fog will probably develop, but with the drier air today,
likely not that widespread.

With decent cloud cover overnight, temperatures will remain
warm and in the 70s through much of the region, with some mid to
upper 60s across the southern poconos and northwestern new
jersey.

Short term 6 am Wednesday morning through 6 pm Wednesday
Heat advisory remains in effect through Wednesday.

Another active day is in store for Wednesday as the
aforementioned frontal boundary pushes north of the region,
placing us firmly in the warm sector. Winds that have been more
southeasterly through today will turn more to the southwest and
we will see moisture increase across the region once again with
dew points rising into the low to mid 70s.

Hot and humid conditions will prevail with little relief
expected until showers and thunderstorms start to develop and
move through the forecast area. A pre-frontal trough will
develop ahead of the main front (which arrives Thursday) and
will be a focus for thunderstorm development across the region.

The main concern will be the potential for severe weather. The
spc has placed portions of our area in the slight risk category,
with damaging winds being the main threat. Shear is modest
(only around 20- 30 kts) but with CAPE increasing through the
day to around 1000-2000 j kg and plenty of moisture and lift
available, we could see some strong to severe storms develop,
mainly during the afternoon and evening and primarily to the
north and west of the i-95 corridor. Once again, pwats are
running high (up to 2.00") so heavy rainfall will be likely and
may result in some flooding concerns.

Long term Wednesday night through Tuesday
We should be solidly in the warm and humid air on Wednesday
evening, with ongoing showers and thunderstorms. The warm front
is expected to be well up into new england at that time with an
approaching cold front extending across the eastern great lakes
and the lower ohio river valley.

The showers and thunderstorms are expected to weaken gradually
on Wednesday evening with the loss of daytime heating. Partly
cloudy and muggy conditions are anticipated for late Wednesday
night.

The cold front is forecast to extend from northern new england
to the ohio river valley on Thursday morning. The boundary will
likely sink slowly to the south, passing through our region from
late Thursday into Thursday night. We are expecting another hot
humid day. Heat index values may again approach 100 from the
philadelphia metropolitan area southward. However, conditions
seem borderline and we will not extend the heat advisory at this
point although it may need to be done as we get closer in time.

Another round of showers and thunderstorms is forecast ahead of
and with the cold front from Thursday afternoon into Thursday
evening.

Some improvement is expected on Friday as high pressure begins
to build down into our region from ontario. There is a chance of
showers and thunderstorms from northeastern maryland and
delaware into southern new jersey as the departing front remains
nearby to our south.

The center of the high is anticipated to shift from ontario to
canada's maritime provinces over the weekend. This pattern will
keep our region in dry conditions with a developing northeast to
east flow. Temperatures will be cooler than what we are
currently experiencing and humidity levels will be noticeably
lower.

The onshore flow may bring a return of some moisture early in
the new week. We have included a slight chance of showers and
thunderstorms at that time.

Wednesday... Lingering MVFR ifr conditions (mainly at kacy kmiv)
in the morning should clear by 15z and thenVFR is expected
through much of the day. Showers and thunderstorms will again
develop across the region and there will be the potential for
MVFR or lower conditions to occur during the afternoon and
evening, especially from kphl and northward. South to southwest
winds around 5 to 10 knots early will strengthen into the
afternoon, with some gusts around 15 to 20 knots possible.

Outlook...

Wednesday night... MVFR and ifr conditions with a chance of
showers and thunderstorms. Southwest wind 5 to 10 knots.

continue to be a chance of showers and thunderstorms with
locally MVFR and ifr conditions. West wind 5 to 10 knots.

Sub-advisory conditions are expected to continue through
Wednesday. Seas will generally be around 2 to 4 feet. Winds are
expected to pick up from the southwest Wednesday afternoon and
gusts may approach 25 knots, especially later in the day. For
now, keep winds just below SCA criteria but cannot rule out a
few gusts around 25 knots.

Isolated showers and thunderstorms may lead to locally higher
winds and waves.

Outlook...

Wednesday night through Sunday... No marine headlines are
anticipated.

Rip currents...

with waves forecast at 2-3 foot and a 6-7 second period, along
with southerly winds 5-10 knots, the risk for dangerous rip
currents is low into tonight. Waves in the surf zone will likely

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.
