Synopsis
Strong low pressure off the new england coast this morning will
move northeastward, reaching nova scotia this evening. High
pressure is expected to build into our region from the west for
Saturday and Sunday. A cold front approaching from the northwest
is anticipated to arrive on Sunday night with another cold
front following on Tuesday. High pressure is expected for
Wednesday and Thursday.

Near term until 6 pm this evening
The coastal storm continues to wrap up and pull away from the
region. Rains snow showers N E are diminishing. Headlines have
been taken down. Gusty W to NW winds up to 30 mph will continue
into the afternoon.

We are expecting a decrease in cloud cover today as the storm
moves farther away from our region.

Maximum temperatures are forecast to be mostly in the 40s, with
readings not getting above the 30s in the elevated terrain of
the poconos and far northern new jersey.

Short term 6 pm this evening through 6 am Saturday
Dry air will continue to build into our region from the west
for tonight. We are anticipating a mostly clear sky along with
a west wind around 5 to 10 mph.

Low temperatures are expected to range from the upper 20s to
the lower 30s.

Long term Saturday through Thursday
We move into a relatively quieter pattern following the coastal
storm. The weekend looks fairly tranquil.

The strong area of low pressure associated with the coastal
storm that has contributed to the first real blast of winter
weather will continue to move away to our northeast, leading to
a cool, but fall-like stretch of weather Saturday and Sunday.

Cloud cover to the north across the poconos and northern new
jersey Saturday will slowly build southward through the weekend,
but conditions will remain dry. A subtle cold front surface
trough will move across the area Saturday afternoon, but we will
remain dry across the forecast area. While highs will still be
about ten degrees below average, it will feel nice compared to
today's well-below average high temperatures.

A cold front is expected to reach our region on Sunday night.

There may be some light snow and rain showers with the feature
from Sunday into Monday, mainly in eastern pennsylvania, and in
northern and central new jersey. High pressure should return for
the middle of the new week, building just to our south.

The normal high temperatures for the period range from the
middle 40s in the elevated terrain of the poconos to the middle
50s on the coastal plain. Highs will remain on the cool side
throughout the area next week, with Monday likely being the
warmest day ahead of the cold front with highs ranging from the
upper 30s in the poconos to low 50s over southern delaware.

Highs look remain generally below 50 across the forecast area
throughout the remainder of next week.

Aviation 14z Friday through Tuesday
The following discussion is for kphl, kpne, kttn, kabe, krdg,
kilg, kmiv, kacy and surrounding areas.

Today... Lingering MVFR at kacy and kmiv through about 15z, then
improvement toVFR.VFR elsewhere for the remainder of the day.

West northwest wind 15 to 25 knots with gusts into the 30s.

Tonight...VFR, mainly clear. West wind 5 to 10 knots.

Saturday-Saturday night...VFR conditions.

Sunday-Monday...VFR conditions expected with a chance of
showers.

Monday night-Tuesday... GenerallyVFR conditions expected.

Marine
The last of the storm warning was allowed to expire at 6:00 am.

A gale warning is in effect until 4:00 pm for the coastal
waters of new jersey and delaware. A gale warning is in effect
for delaware bay until 1:00 pm. Wind speeds will be slow to
decrease as the strong area of low pressure moves northeastward
and away from our region. The wind direction on our waters will
settle into the west northwest.

Outlook...

Saturday-Tuesday... Conditions expected to remain below advisory
levels with west-northwest winds 10-15 knots.

Tides coastal flooding
The storm surge increased to 3+ feet along the central and
northern parts of the new jersey coast out ahead of the coastal
storm overnight. As a result, there was minor coastal flooding
with some localized moderate flooding.

Fortunately, the astronomical tides are quite low as we are at
the first quarter phase of the moon. If the 3+ foot surge took
place around the time of a new or full moon, we would have been
experiencing moderate to major flooding.

The overnight high tide should be the only cycle of concern.

The wind is forecast to be westerly for this afternoon's high
tide, pushing water away from the coast.

Phi watches warnings advisories

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.
