Synopsis
High pressure over southeast canada moves east and offshore
tonight. Low pressure moving through the great lakes will pass
north of the area on Tuesday and drag a cold front through the
region by Tuesday evening. High pressure builds in from the west
on Wednesday, and then weak low passes through on Thursday. A
coastal low may affect the region on Friday, and then high
pressure returns for the weekend.

Near term until 6 am Tuesday morning
High pressure offshore will move to the east tonight while
strengthening low pressure moves towards the lower great lakes
region. These features will bring increasing clouds to the area
tonight along with a slowly increasing srly winds. Low
temperatures will range from the mid upper 20s across the north
to the low 30s over metro philadelphia and delmarva. Light snows
will likely affect the SRN poconos and NRN nj well after
midnight. We have increasing pops for these areas with small
(around 1 inch) accumulations for the higher elevations.

Short term 6 am Tuesday morning through 6 pm Tuesday
Low pressure will continue to strengthen while moving across ny
and into new england Tuesday. Light snows across the north will
continue through the morning and then diminish as a cold front
crosses the area. Further south, the chc for measurable precip
will be less, but some light snows are possible and areas
further south will have light rains. A limited confid fcst with
regards to QPF amts. After the cold front crosses the area,
winds will shift to W and increase to 15 to 25 mph with gusts
over 30 mph. Temperatures will be highest early in the day, then
fall through the afternoon, as the cold air advection
increases.

Long term Tuesday night through Monday
The long-term period continues to show a long-wave trof pattern
over the eastern us with several shortwave trofs rotating
through. The trof is deepest at the beginning period Tuesday
night with a roughly 505dam closed upper low forecast over ny
state. The associated surface low will deepen as it moves
northeast from new england into canada, maintaining strong nw
winds and CAA over the area through Wednesday. Some snow showers
are possible, mainly over the poconos.

For Thursday and Friday, temperatures should moderate slightly
but remain well below normal. A couple of fast-moving low
pressure centers could scoot past to our south and possibly
bring some light snow to the area.

The outlook for next weekend ATTM suggests temperatures
returning to near normal. Saturday looks mainly dry, but by
Sunday another low pressure may approach from the SW and bring a
a mix of rain and snow late Sunday into Monday. Confidence in
this system is rather low.

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.
