Synopsis
A cold front will drop south through the region today and will
be followed by high pressure building south from canada tonight.

High pressure will crest over the area Monday morning before
shifting east through Monday night. A warm front will approach
from the southwest on Tuesday and will lift into northern maine
Tuesday night. Low pressure will move northeast through central
quebec on Wednesday and will drive a trailing cold front through
the region Wednesday night. High pressure will build in from the
west on Thursday.

Near term until 6 pm this evening
700 am update...

quick update to mainly adjust current temps tds. Last of high
clouds on the way out of southeastern new hampshire and clouds
associated with a weak cold front approaching the canadian
border. Should see several hours of mostly sunny skies in the
north before clouds settle south. Extensive valley fog should
quickly lift in northern zones and the connecticut valley.

No major changes planned to current forecast.

Prev disc...

persistent band of cirrus continues to gradually sink south
early this morning and has pretty much cleared northern zones
where temperatures are approaching freezing. Thicker cloud over
central and southern zones helping to keep temps up and may
prevent frost formation... Especially in the lower connecticut
valley. Expect this cloud cover to gradually push south of the
region through mid morning.

Looking for mostly sunny skies across most of the region by late
morning before a cold front dropping south from canada brings
mid level clouds into northern zones later this afternoon. Not
looking for much more than variable clouds with this moisture
starved boundary which should push south of the area by this
evening. High temperatures today will from the mid 50s to mid
60s north and upper 60s to near 70 in the south.

Short term 6 pm this evening through 6 pm Monday
High pressure will build south from canada overnight. Looking
for scattered to broken clouds behind the front lingering
mainly in northern and central zones. Will once again see some
chilly overnight lows with upper 20s to mid 30s north and upper
30s to mid 40s in the south.

High pressure will crest over the region early Monday before
shifting east in the afternoon. Looking for a mix of Sun and
clouds and cooler temps with highs ranging through the 50s.

Long term Monday night through Saturday
Models are in general agreement on the overall flow pattern through
the period, but differ on locations and movement of the smaller
scale features. With rather fast flow developing across the
northeast, timing of specific weather features is difficult.

High pressure centered over northeastern maine Monday evening
will drift slowly south and east through Wednesday. As it does,
a developing southerly flow will lead to warming temperatures
and increasing moisture across the region. The initial push of
warm advection aloft will likely lead to a period of steady rain
Tuesday afternoon and evening. The rain should taper to showers
by Wednesday morning. A cold front will then push through the
region Wednesday afternoon and evening with another round of
showers and possibly a thunderstorm.

A ridge of high pressure will build across the region for Thursday
as the cold front continues to slip southward. An area of low
pressure will develop along the front and move northeast during the
day Friday. Models differ on location and movement of this frontal
boundary, intensity of the developing low, and how far north the
precipitation shield comes. Current model forecasts would limit any
significant precipitation from this feature to mainly south of the
region, although the GFS brings some light precipitation to coastal
areas. Also on Friday, an area of low pressure moving through
southern canada will drag a cold front toward the region during
the day. This front will cross the region late Friday and sweep
any remaining precipitation out to sea. Drier air will follow
for Saturday. Models differ for Sunday with ECMWF mainly dry,
but the GFS brings another frontal boundary through the region.

Aviation 12z Sunday through Thursday
Short term...VFR today through Monday with areas of ifr lifr in
morning valley fog this morning and again Monday morning.

Long term... MainlyVFR conditions (except for lifr conditions
Monday night in valley fog) expected Monday night into Tuesday
with MVFR to ifr conditions developing Tuesday and persisting
into Wednesday evening. Lifr conditions are possible in any
heavy showers or thunderstorms during the period.VFR conditions
should return Thursday.

Marine
Short term... Northeast flow will pick up behind the cold front
tonight as high pressure builds in from the north. Looking for
sca winds developing around midnight and persisting into early
afternoon Monday.

Long term... Scas possible Tuesday through Thursday as an increasing
southwest flow develops across the waters through Wednesday. A cold
front will cross the waters Wednesday 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.
