Synopsis
A cold front will drop south through the region this evening
and will be followed by high pressure building south from canada
overnight. The high will crest over the area Monday 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 and Friday.

Near term through Monday
Update...

have updated the forecast based on current surface observations
and satellite observations. Mainly clear skies continue over
central areas, with high clouds across the far south and low to
mid level cloudiness over the north. Temperatures continue to
drop through the 40s in all but far southern areas which were
holding in the lower 50s as of 02z. Have backed off a tad on
the late night wind forecast for coastal areas and lowered the
gusts. Also added patchy late night fog across the northern
valleys after midnight.

Prev disc...

a cold front currently draped just north of the
border will drop south out of canada and into maine and new
hampshire tonight. These clouds and the increasing winds behind
the front will help to keep temperatures slightly warmer than
last night, enough to prevent a frost in all but the easternmost
areas. Through somerset and interior waldo clearing skies
behind the front near daybreak may allow for some patchy frost
to form in the valleys and a frost advisory has been issued.

Short term Monday night
High pressure will build in for Monday. Temperatures will be
cooler than the past few days with the high temperatures in the
50s. Overnight expect clear skies in the north to once again
allow temperatures to drop to near freezing and additional frost
advisories are possible.

Monday night increasing cloud cover starts to encroach on the
southwestern portion of new hampshire as low pressure begins to
move out of the ohio valley.

Long term Tuesday through Sunday
A large anticyclone will remain over the canadian maritimes on
Tuesday. This will set up a moist southeasterly flow to form off
the gulf of maine during the day. Strong warm air advection and
a sufficient moisture supply will lead in showers overspreading
the region along with chilly temperatures in the mid 50s north
to the lower 60s south.

A warm front will lift north of the region Tuesday night into
Wednesday, driven poleward by an increasing southwesterly
gradient. Some of the showers during this period may be locally
heavy as precipitable water values and surface dew points will
be on the rise. An outside chance for a thunderstorm remains
possible as well on Wednesday.

By Thursday, high pressure over the great lakes will allow drier
air to enter new england. Cold air advection will be limited, so
a significant cool down is not expected.

12z model guidance suggests low pressure will linger east of the
gulf of maine on Friday before it is swept out to sea. This will
be followed by high pressure building east for next weekend.

Aviation 02z Monday through Friday
Short term...VFR conditions will continue through tonight and
into Monday night everywhere except the connecticut river valley
where overnight valley fog will drop leb and possibly hie to
lifr.

Long term... 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... Gusty winds in the wake of a cold frontal passage
will reach 25 to 30kts early Monday morning and a SCA has been
issued.

Long term... Scas possible Tuesday and Wednesday as an
increasing southwest flow develops across the waters. A gusty
northwest flow will follow the front Thursday.

Gyx watches warnings advisories
Me... Frost advisory from 2 am to 9 am edt Monday for mez014-022.

Nh... None.

Marine... Small craft advisory until 2 pm edt Monday 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.
