625 am est Tue jan 16 2018

A ridge of high pressure will weaken across the area today. A
low pressure system and front will approach from the great lakes
region tonight. Another low will develop off the coast and
affect the weather tonight and early Wednesday. More high
pressure will build towards the area late this week and remain
for the weekend. Low pressure and a cold front will move towards
the middle atlantic region for the start of next week.

Near term until 6 pm this evening
Weak low pressure over the great lakes will push a cold front
toward our region today. Meanwhile, a secondary low is forecast
to begin developing off CAPE hatteras this afternoon.

We continue to expect snow today in parts of eastern
pennsylvania and northern new jersey. The remainder of our
forecast area should remain mostly cloudy with no precipitation
during the daylight hours.

An initial shot of light snow will affect berks county, the
lehigh valley, the poconos and the northwestern edge of new
jersey early this morning. Any accumulation should be around an
inch or less. The more substantial snow is expected to move into
those areas from the northwest during the course of the

We have made some adjustments to the timing of the winter
weather advisory, delaying the start time in all but berks
county, the lehigh valley and the poconos.

The wind is expected to remain fairly light today. High
temperatures should favor the 30s in eastern pennsylvania and
northern new jersey. Readings are forecast to rise into the
lower 40s on the coastal plain.

Short term 6 pm this evening through Wednesday night
The secondary low is forecast to strengthen gradually as it
moves northward off the coasts of delaware and new jersey
tonight, then over the coastal waters of new england on
Wednesday. The system will likely throw some precipitation back
over our region for tonight and Wednesday morning.

The precipitation type will favor snow. However, the boundary
layer is expected to be warm enough for some rain on the coastal
plain during the first half of the nighttime period.

We continue to expect a substantial snow in the northern part
of our forecast area. Amounts of 4 to 6 inches are anticipated
for the poconos with totals tapering down to perhaps an inch or
two in the philadelphia metropolitan area and southern new
jersey. Little or no snow accumulation is expected for the
delmarva south of the canal and for far southern new jersey.

The precipitation is expected to be mainly off our coast by
Wednesday afternoon with some clearing late in the day.

A light wind for much of tonight should become northwest around
10 mph toward daybreak on Wednesday. The northwest wind is
forecast to increase to 10 to 15 mph on Wednesday with some
gusts near 20 mph.

Low temperatures tonight should be mainly in the 20s. Readings
should recover only slightly on Wednesday with highs mostly in
the upper 20s and lower 30s.

Long term Thursday through Monday
The upper low that affected the weather in the near short term
parts of the forecast will be moving though the tidewater area
and it will take the last of the precip with it. We only has a
few lingering showers Wed evening across the ERN srn most parts
of the area. Sprawling high pressure from the southern
mississippi valley will begin to move into the area. Dry weather
is expected for Wed night and into Thu Fri as the high builds.

Temperatures will be below normal until Friday, when readings
will be near normal.

The high continues to affect the weather this weekend, so more
fair weather is expected. The airmass will moderate as the upper
ridge continues to build. Temperatures will be closer to 10
degrees above normal by Saturday and the near 15 degrees above
normal by Sunday.

The next low pressure system will be rather intense as it moves
from the plains states to the great lakes area early next week.

We will be on the warmer side of the system, so mostly rain is
expected at this time. Temperatures will still be much above
normal Mon before returning closer to normal tue. High chance
and low likely pops (srn poconos) are in the fcst at this time.

Pops decrease back to slgt chc for Tuesday after the cold front
crosses the area.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
