Synopsis
Strong low pressure along the new jersey coast early 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 was located along the southern new jersey
coast around 4:00 am. The low will continue to progress
northeastward today. As it moves away from our region, the wind
will become westerly around 15 to 25 mph with gusts of 30 to 40
mph. Wind speeds may begin to diminish slowly this afternoon.

A mid level low approaching from the west will pass over eastern
pennsylvania and northern new jersey early this morning. It will
bring a parting shot of snow showers and rain showers until
about 8 or 9 o'clock. Any additional snow accumulation is
expected to be limited. However, some spots from the interstate
78 corridor northward could pick up another inch or so.

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 09z Friday through Tuesday
The following discussion is for kphl, kpne, kttn, kabe, krdg,
kilg, kmiv, kacy and surrounding areas.

Today... Ifr conditions with scattered rain and snow showers
through about 12z, then improvement toVFR 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.

Outlook...

Saturday-Saturday night...VFR conditions.

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

Monday night-Tuesday... GenerallyVFR conditions expected.

Marine
The storm warning remains in effect for the northern and
central coastal waters of new jersey until 6:00 am. A gale
warning is in effect until 4:00 pm for the southern coastal
waters of new jersey and for the coastal waters of 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 early this
morning.

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. As a result, a coastal flood advisory remains in effect
for the counties of ocean, monmouth and middlesex until 6:00 am.

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.

This should be the only high tide cycle of concern. The wind is
forecast to be westerly for this afternoon's high tide.

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.
