Synopsis
High pressure across the central gulf coast will build eastward
today, then offshore over the weekend. An area of low pressure
will move across eastern canada over the weekend as a back door
cold front approaches from the north. Another area of low
pressure will move through the great lakes Monday night into
Tuesday, pulling a cold front across the area. High pressure
will build toward the area late Wednesday into Thursday of next
week.

Near term until 6 pm this evening
No major changes with the morning update. Surface high pressure
builds in from the west, allowing for rising heights and
thicknesses. Highs will be some 8-10 degrees warmer today than
Thursday, topping off in the mid to upper 30s north and west of
the fall line, and in the low to mid 40s across southern nj and
southeast pa, and in the mid to upper 40s in the delmarva.

Short term 6 pm this evening through 6 am Saturday
High pressure continues to build in from the west and heights
continue to rise. This results in overnight lows warmer tonight
than this morning, but there will still be some radiational
cooling that allows temperatures to drop into the teens and
lower 20s. Otherwise, lows will be generally in the mid 20s.

Long term Saturday through Thursday
Quiet weather continues into the weekend, with a return of
unsettled weather for early next week, followed by quiet weather
again for the middle of next week.

Dry conditions will continue for Saturday and Saturday night as
high pressure builds to our south across the southeastern
states then offshore Saturday. We will remain on the northern
periphery of the high which will keep a dry, west to southwest
flow across the area. Winds on Saturday are expected to gust
20-25 mph at times during the afternoon.

On Sunday, a back door cold front will sag toward our area from
the north as an area of low pressure slides eastward across
eastern canada, and cold high pressure builds across eastern
canada through Sunday night. Sunday is expected to remain dry,
but cloud cover will be on the increase through the day.

As we move into Sunday night and Monday, the back door frontal
boundary is forecast to make its way across a portion of the
area. As it does so, there will be some enhanced moisture and
lift moving overtop of the front. This may lead to some light
rain drizzle developing across the area Sunday night into
Monday. Temperatures are expected to drop below freezing for
portions of northern new jersey and northeastern pennsylvania as
some cold air gets dammed up. If any precipitation does occur,
this could lead to some light freezing rain or drizzle overnight
Sunday into Monday morning.

Then Monday night into Tuesday morning, a cold front is
expected to sweep across the area as an area of low pressure
moves through the great lakes region. This will lead to a period
of rainfall overnight Monday into Tuesday. It is possible that
the rain could change over to snow across northern new jersey
and northeastern pennsylvania before the precipitation ends
Tuesday morning behind the cold frontal passage.

For Tuesday night into Wednesday, the low pressure system moves
across eastern canada, while a secondary cold front moves
toward the area from the west, which may cross the area during
the day. Most of the area will remain dry, as any precipitation
is forecast to remain to our north. If there is any
precipitation, it would most likely occur across portions of
northern new jersey and northeastern pennsylvania.

High pressure returns for Thursday, leading to dry conditions.

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.
