Synopsis
Canadian high pressure remains in control through Thursday as a
low passes well south of the region through this afternoon. A
cold front moves through mid week. A frontal system and
associated low pressure will impact the area at the end of the
week into the first half of the weekend.

Near term until 6 pm this evening
Forecast is on track with only minor edits made to reflect
current conditions.

Despite plenty of sunshine, dry and chilly weather will continue to
start the work week as canadian high pressure builds into the
region. Northerly winds will increase this morning as the pressure
gradient briefly tightens between the building high and a departing
low well south of the region. This will primarily serve to make
highs around 40 feel several degrees cooler. These temperatures are
about five degrees below normal for early-mid december.

Short term 6 pm this evening through 6 pm Tuesday
Winds will become light Monday evening as the pressure gradient
weakens, setting the stage for good radiational cooling conditions
across outlying areas. Overnight lows will fall into the mid teens
in typically cooler outlying areas and to around 30 in new york
city.

Another cool and dry day is expected on Tuesday, with high
temperatures a degree or two colder than today. By afternoon, an
upper trough and associated weak surface low crossing the great
lakes will begin to approach the region, but conditions are expected
to remain dry with little appreciable increase in cloud cover
through the daylight hours.

Long term Tuesday night through Sunday
An upper level northern branch trough will move through the
northeast Tuesday night, bringing a cold front through during this
time frame. Moisture seems limited with this system. In addition,
lift also seems limited in the middle to upper layers, with
subsidence noted in the lower layers. So, will keep a dry forecast
Tuesday night into Wednesday. Lower thicknesses on Wednesday will
mean temperatures remain below normal.

Canadian high pressure builds in from the north and sinks south into
new england Wednesday night, pushing off the new england coast
Thursday. Return southeasterly flow and ridging aloft will allow
temperatures to warm for Friday. Highs on Friday will be a few
degrees above normal for this time of year.

With the high pressure off shore, this opens the door for a frontal
system to our west and low pressure to our southwest to approach the
area on Friday. These systems will impact the region beginning late
Friday Friday night for western sections and overspread the entire
area late Friday night. A weak area of low pressure is forecast to
develop along the frontal boundary that approaches the area and will
push off the mid-atlantic coast Saturday, passing south and east of
long island. There is still some uncertainty with the strength and
track of the system. However, at this time, it appears to be warm
enough for precipitation to start off and remain plain rain
throughout the event.

High pressure builds in late Saturday night, with Sunday being dry.

Aviation 12z Monday through Friday
High pressure remains in control. A weak cold front drops from
the N today, but is expected to dissipate before making it to
any of the local terminals.

Other than a few patchy stratocu approaching from the northwest
early this morning,VFR conditions will prevail through the taf
period.

N winds generally 7-12kt highest along the coast. A few gusts
to 15-20 kt cannot be ruled out through 18z or so. Winds
diminish as the afternoon progresses, and lighten further this
evening.

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.
