Synopsis
High pressure will move east into the western atlantic through
Monday. Low pressure and its attendant cold front will sweep
through the area Tuesday. Troughing will remain overhead for
much of the second half of the week.

Near term until 6 am Sunday morning
High pressure resudes across the northeast and mid atlantic
section of the conus. In spite of this, ample upper level
moisture has drifed atop the ridge, resulting in a deck of
cirrus. Skies became mostly cloudy if not cloudy just prior to
sunset, and remains so at this time. IR satellite and rap bufkit
overview suggest there will be little change until the pre-dawn
hours. Have made these adjustments in the sky grids. Will be
assessing if low temperatures need to be bumped up slightly
shortly.

Short term 6 am Sunday morning through Monday night
Quiet wx sun-sun night under high pressure. Clouds begin to
increase Mon with showers expected by midday on the west and
spreading east through the afternoon. Heavy showers with
possible t-storms and gusty winds Mon night as cdfnt enters the
area.

Long term Tuesday through Saturday
Strong front moving through Tuesday is main story in long term. This
system looks potent with potential for a period of heavy, wind swept
rain ahead of and along the primary cold front. Strong southerly
fetch ahead of it should bring copious moisture north, but speed
should limit flood concern. Gusty winds possible with very strong
low level jet, but most likely any winds of a threatening nature
will be limited to the cold frontal passage itself - low topped
squalls possibly embedded within larger rain band is the concern.

Timing remains a bit uncertain but right now, its favoring the am.

Breezy and much cooler behind the front, with the coolest days
likely Wednesday-Thursday. Some freeze issues are possible, though
this cold shot looks very transitory and if it doesn't align with a
good radiational night, it just might be chilly versus freezing.

Upper trough plus wraparound moisture might result in a few showers
Wednesday as well, especially in the mountains. If its cold enough
in the higher terrain, these could well be snow showers.

Drying out and moderating Friday with high pressure building in.

Aviation 01z Sunday through Thursday
Vfr conditions through Sunday evening. A southerly flow will
strengthen ahead of a cold front overnight Sunday and Monday.

Moisture streaming into the area will cause more clouds along with
the possibility for subvfr cigs. Patchy fog is also possible
overnight. The cold front will pass through overnight Monday
into early Tuesday. Llws is possible during this time.

A soaking rain is also expected with the frontal passage and there
is a potential for heavy rain and ifr CIGS vis, along with gusty
winds - perhaps isolated 30-40 knot gusts. Timing still a bit
uncertain but right now favoring between 06z-12z early Tuesday.

After that, NW wind may be gusty, but becomingVFR overall for the
rest of the week. A few showers possible, mainly Wednesday, but
cig vis reductions should be minimal.

Marine
Winds will begin to strengthen Mon in srly flow. SCA conditions
likely by late Mon and solid SCA conditions expected tue.

Gales possible Tuesday as strong cold front barrells through. Sca
possible Wednesday as the system moves away and high pressure builds
in.

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.
