Synopsis
High pressure across the region this evening will weaken overnight.

A weak low pressure area will move across new england overnight and
cause a cold front to move through by Wednesday morning. More
high pressure returns for later Wednesday and Wednesday night, but
another low will then cross our area Thursday. More low pressure
moving towards the area from the southern u.S. Will affect our area
later Friday and into the weekend.

Near term until 6 am this morning
A cold front continues to works its way south and will be
through the region by daybreak. There is limited moisture, but
some light snow and flurries are possible across the southern
poconos and into northern nj. Little snow accumulation is
possible across higher elevations of far northern zones.

Skies clear out by daybreak.

Winds will be 10 mph or less from the west, maybe a little north of
west.

Short term 6 am this morning through 6 pm Thursday
High pressure at the surface combined with a brief mid-level
ridge will help produce another sun-filled day. Some ci could
increase in the afternoon, but all-in-all, the region will see
quite a bit of sun.

Winds will continue from the west northwest. Speeds will be
less than 15 mph, except for in the morning where a few gusts up
to 20 mph are possible.

Afternoon high temperatures will land in the below normal
range, mainly low 30s to low 40s.

Long term Thursday night through Tuesday
There are two system of interest in the long term part of the forecast.

First is the upper low pressure system (with weak sfc reflection)
slated to arrive for Thursday. The recent NAM model is making the
most with this feature showing showers across the region during the
day. Temperatures on the met are colder and p-type of snow is shown
since the air will be rather dry and evap cooling will be taking
place. We have upped the pops slightly, but still not as highs as
offered by the nam MOS with its high chc (and low likely 12 hr pops).

The GFS also has the low moving through the area, but dry. It's
daily temps (mav mos) are some 5 degrees warmer than the met. Precip
will probably be showery, so p-type for Thu will be snow showers
with chc (30) pops for mostly the N W areas. There is still some
degree of uncertainty with this fcst however.

Speaking of uncertainty, the second system is still not being well
handled by the various 12z op models. The cmc is showing a deep
low moving well west of the area. The GFS ec are showing the lows
moving closer to our area. There are actually two lows. The ec only
has one affecting our area (fri night early sat), while the gfs
brings the first low through with a trailing low across the area
later Sat and Sunday. Consequently, the gfs's QPF is much higher
than the other models. The bufkit profiles for the GFS in our
area have 1 to 2 inches of rain for many spots. We will maintain
our likely to categorical pops for Fri night sat, but just keep
the chc for the later Sat into sun. Period. If the GFS becomes
the preferred model, pops for later sat- Sun will have to be
raised.

Dry weather is expected Mon Tue attm. Confid in later periods is
low however with the models in disagreement.

Temperatures will be a little below normal thu, the become above normal
for Fri and sat. Readings will then be close to normal for Sun before
going back below normal towards the middle of next week.

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.
