Synopsis
A warm front continues to lift north of the area this morning,
followed by a cold frontal passage this evening. High pressure
builds in from the great lakes Saturday into Sunday. Weak low
pressure will pass to the south Sunday night into Monday
morning, followed again by high pressure later Monday through
Tuesday. The high will be slow to retreat to the northeast
Tuesday night into Thursday as a low pressure system approaches
from the southwest.

Near term until 6 pm this evening
Slowed down the west to east progression of diminishing clouds
for this afternoon. Rest of the forecast pretty much on track.

Area of sct showers over the forks region and SE ct will be
exiting east within the hour. Mostly dry otherwise with an
isolated shower still possible over SE ct, and well as a chance
of showers far NW towards the end of the day. Mild, with highs
in the 50. Maybe even a spot or two around 60 in NE nj.

Short term 6 pm this evening through 6 pm Saturday
A primarily dry cold frontal passage this evening, but there
could be at least isolated scattered showers right ahead of the
front. Cold front clears far eastern areas toward midnight with
moderate cold advection. Lows by morning will range from the
mid 20s well inland to the lower 30s at the coast. Highs on
Saturday will return to seasonable levels at around 40.

Outside of some high clouds overnight into Saturday morning,
conditions will be dry. A wave of low pressure along the frontal
boundary will remain well south of the area.

Long term Saturday night through Thursday
As an upper trough pulls away from northern new england
into the canadian maritimes, mid level confluence in its wake will
support sfc high pressure going into Sat night and Sunday. How
quickly this confluent flow aloft pulls away will help determine
chances for some light snow Sunday night into mon. Tonight's ecmwf
has trended toward the GFS idea of this confluent zone being weaker
and displaced far enough north into quebec to allowing shortwave
energy shearing out from a weak closed low over the plains states to
approach during this time and make a more direct run at the area,
perhaps generating some light snow on the order of up to an inch at
most Sunday night into early Mon morning.

High pressure will once again return in the wake of this system for
later Monday into tue. Then another round of light wintry precip
becoming increasingly likely going into the mid week period with the
high slow to retreat and a double-barreled low moving up from the
southern states. Scenario somewhat like last week's winter wx event,
with one low tracking west across the lower great lakes and another
passing just south, with fast wsw flow aloft. This points to a light
snowfall mainly from daytime Wed into Wed evening, transitioning to
a mix of snow sleet freezing rain late Wed night into early thu
morning, then all rain the rest of daytime thu.

Temps through much of the period should remain below normal as a
whole, but arctic cold not expected.

Aviation 18z Friday through Wednesday
GenerallyVFR with a low chance of MVFR ceilings today and a
slight chance of rain showers as a cold front moves through late
this afternoon into this evening. A period of llws is also
possible for eastern terminals such as kisp and kgon through
this afternoon as a low level jet translates east.

S to SE winds 10 to 15 kt. Gusts for the city terminals have
generally diminished, but there may be an occasional gust of
20-25 kt over the next couple of hours. Winds begin to shift to
the SW then W with the approach and passage of the cold front
late in the afternoon and into the evening. Winds then become nw
around 10 kt late in the forecast.

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.
