Synopsis
High pressure builds across the region through mid week. A warm
front passes to the north late Wednesday night into Thursday
morning, followed by a cold front Thursday afternoon into Thursday
night. Another cold front moves through the area on Friday, followed
by high pressure for the weekend.

Near term until 6 pm this evening
The forecast is mainly on track. Updated hourly temperatures and
dewpoints based on latest obs and trends. Still think clouds
should gradually increase this afternoon as a shortwave trough
passes north and weak low pressure passes south. Otherwise,
modified canadian high pressure will move across the region
today, with seasonably cool temperatures continuing and light
winds. Dry conditions are forecast.

Afternoon mixing will allow dew points to fall into the single
digits and teens, yielding minimum relative humidities in the
mid 20s to lower 30s. Although finer fuels (i.E. Grasses,
litter, etc... ) will be drier, light winds and recent rainfall
should act to limit fire potential. As such, a special weather
statement was not issued at this time, though with dry
conditions expected the next few days, fire weather conditions
will need to be monitored.

Short term 6 pm this evening through 6 pm Tuesday
High pressure will continue to build over the area into
Tuesday. With light winds and clear skies tonight, favorable
radiational cooling conditions will allow temperatures to fall
to below normal values.

A slow moderation of the air mass will occur into Tuesday, with
temperatures rising a few degrees above the previous day, though
still a few degrees below climatological normals. Once again
conditions will remain dry, with little sensible weather.

Long term Tuesday night through Sunday
The overall synoptic pattern continues to be fairly well resolved by
nwp for the middle of the week into the upcoming weekend. The
pattern over the northeast will be dominated by mean troughing
through the end of the week with ridging beginning to return this
weekend. Differences arise with the handling of shortwave energy
within the trough as it amplifies Wednesday night through Thursday
night, which could impact sensible weather across the tri-state.

There are also differences with the handling of another of a
potential upper low within the trough as it moves off the new
england coast Friday night into Saturday.

Tuesday night through Wednesday... High pressure will be centered
over the region Tuesday night and then gradually move offshore on
Wednesday. Temperatures Tuesday night fall into the 20s inland and
lower 30s elsewhere. The air mass should moderate back to near to
slightly above normal levels with highs in the upper 40s and low
50s. As the high pressure moves offshore Wednesday, a shortwave
dives south towards the great lakes and another emanating from the
plains slowly moves eastward.

Wednesday night through Thursday night... The upper trough amplifies
with the aforementioned shortwaves coming into interest. The northern
piece of energy will help send a frontal system towards the region
Wednesday night with a warm front lifting north through Thursday
morning. A cold front will follow Thursday afternoon and evening.

However, will need to watch for any interaction of the northern
energy with the southern energy that ejects out of the plains. The
00z cmc, GFS and many of its ensemble members have the two pieces of
energy staying separate with the southern energy moving off the
southeast coast. The 00z ECMWF indicates interaction and possible
phasing of the energy leading to a more substantial wave of low
pressure along the coast as the cold front moves through late
Thursday. There are a few 00z GEFS members and 12z ECMWF eps members
that show a scenario similar to the operational ecmwf. Have
increased pops a bit on Thursday, but our official forecast is
contingent on the two pieces of energy remaining unphased. This
would yield a light precip event of a couple tenths of an inch. The
precip could start as a few rain snow showers inland early Thursday
morning, but otherwise plain rain showers are expected as the
temperatures rise into the lower 50s. The front moves offshore
Thursday night bringing an end to the showers. If future model runs
start to show more interaction of the energy and more well define
low pressure, then pops and precipitation amounts would need to be
increased Thursday and possibly Thursday night.

Friday through Sunday... The upper trough will continue to amplify on
Friday as yet another shortwave is progged to dive south out of
southeast canada. This will send the next cold front through the
region late Friday. Have continued with a dry forecast, but with a
vigorous vort max, it would not be surprising if a few showers
developed. An upper low may be carved out by the energy Friday night
into Saturday as the trough moves towards the canadian maritimes.

Heights then begin to rise for the remainder of the weekend with
high pressure returning. Temperatures on Friday will be near normal,
then fall below normal in the 40s on Saturday. Temperatures may then
approach the upper 50s to near 60 on Sunday.

Aviation 14z Monday through Friday
Surface high pressure remains over the region as a few weak
upper level disturbances move across the area.

Vfr. A light N to NW wind will become west-southwest late this
afternoon along the coast. Winds this evening will become light
and variable once again, taking on more of a westerly flow
after 00z.

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.
