Synopsis
A warm front cross the region tonight and will be quickly
followed by a cold front Sunday morning. A secondary cold front
will drop south through the region on Monday. High pressure will
build in from the west Monday night and will crest over the
region on Tuesday before shifting offshore to the southeast as a
weak system passes to the south. A warm front will approach from
the southwest Tuesday night and will move north into the region
on Wednesday. The warm front will push east of the region
Wednesday night. A cold front will approach from the northwest
Thursday and will cross the region Thursday night. High pressure
will build in from the west on Friday.

Near term until 6 am Sunday morning
Update...

showers continue to progress eastward. Have upped pops over
eastern new hampshire and southwest maine where one band of very
light precipitation has set up. Convection continues to fire
over central new york in an area of instability. Have added a
slight chance for a thunderstorm over southern and western new
hampshire as this precipitation moves across the region.

However, the atmosphere remains more stable over much of eastern
new england.

Made minor adjustments to temperatures. Very chilly condition as
of 02z along the coast where an onshore breeze held during the
afternoon and evening hours. Milder conditions with dew points
in the lower to mid 50s continue over portions of western new
hampshire.

Prev disc...

showers and some thunderstorms ahead of a warm front moving
east through new york will get into the connecticut valley by
early evening and will quickly over-spread the remainder of the
forecast area through the evening hours. Cold front not far
behind... Currently moving into the eastern great lakes with
another line of showers and thunderstorms. Expect mainly rain
showers with the warm front as it moves into the region this
evening although a stray rumble can't be ruled out in southern
new hampshire. Low temperatures will generally range through the
50s.

Short term 6 am Sunday morning through Sunday night
Cold front will push into the region early Saturday before
heating has a chance to get going. Think drier air moving in
behind the front will inhibit convection in western zones but
may see enough moisture and instability to pop of thunderstorms
in northern and eastern zones. Expect the front to exit the
region by Sunday evening. High temps on Sunday will range
through the 60s to mid 70s in the north and mid 70s to mid 80s
in the south.

Sunday night looking quiet as a secondary cold front approaches
from the north. Looking for partly cloudy skies overnight. Lows
will range from the mid 40s north to the mid 50s south.

Long term Monday through Saturday
High pressure builds in to the northeast Monday while an upper
level trough moves through southern quebec and northern new
england. The high should be able to support sunny skies for most
of the day before cloud cover associated with the upper level
trough moves in, especially across the far north. Highs should
reach the lower 60s north to 70s elsewhere, with a chance for
high 70s in the manchester nashua area.

On Monday night partly clear to clear skies and light and
variable winds will encourage some cool and even cold
temperatures overnight. Lows in the mid 30s will be common in
the mountains where radiational cooling will be strongest. This
will support some light frost in that region. Elsewhere
temperatures in the upper 30s to mid 40s will be more common.

Fast zonal flow will cross the region on Tuesday, pushing a warm
front through new england. As high pressure moves offshore,
showers will move into the region from the west by Tuesday
afternoon. Secondary cyclogenesis will occur off the mid-
atlantic, possibly bringing additional rainfall to the coast.

There is some difference in the timing of the features among the
models, with the european bringing the system through quicker,
and thus giving us a break in precipitation ahead of Wednesday's
system, which follows closely on its heels. The warm front gets
hung up somewhere over the forecast area, allowing the system
Wednesday afternoon and evening to redevelop along it.

We should see a break in precipitation Thursday afternoon before
additional showers develop along a pre-frontal trough. Finally a
cold front should clear the area very early Friday morning,
producing yet another round of precipitation. High pressure will
bring a much-needed respite from precipitation next Saturday.

Aviation 02z Sunday through Thursday
Short term... MVFR ifr ceilings develop tonight with areas of
MVFR ifr vsby in patchy fog. BecomingVFR on Sunday.VFR Sunday
night.

Long term... High pressure builds in from the northwest Monday
and shifts east early Tuesday withVFR conditions expected. A
warm front tries to lift north into the area as early as late
Tuesday. This should bring increased clouds and ceilings
lowering to MVFR or ifr at times with occasional showers. Could
see some improvement on Wednesday especially if the warm front
is able to lift north of the area.

Marine
Short term... Have issued scas for tonight and Sunday morning
for marginal SCA conditions.

Long term... Light offshore north to northwest flow expected
through Monday as high pressure builds across southeast canada
and northern new england. As high pressure shifts east on
Tuesday, a south to southeast flow develops. A warm front tries
to lift through the region Tuesday night and Wednesday. If low
pressure is able to develop along this front it could bring a
period of small craft advisory level winds, but for now winds
are expected to remain below 25 kt. A cold front arrives from
the west on Thursday.

Gyx watches warnings advisories
Me... None.

Nh... None.

Marine... Small craft advisory until 11 am edt Sunday for anz150-152-154.

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.
