Synopsis
High pressure will build over the region today and will slide
off to the southeast tonight. Return flow will bring a very warm
and humid airmass into the region on Wednesday ahead of an
approaching cold front. Low pressure moving northeast through
quebec Wednesday night will drive a trailing cold front through
the region on Thursday. A trough of low pressure will linger
over the area Thursday night and Friday. High pressure will
build in from the west Friday night through Saturday night and
will hold over the region on Sunday.

Near term until 6 pm this evening
1030 am update... Very little change to the going forecast this
morning. Cloudless or near-cloudless skies should continue into
the afternoon hours with a seabreeze developing at the coast.

700 am update...

patchy light valley fog is quickly burning off across the region
and aside from a few high clouds in southern zones later
today... Should see sunny skies through this evening. Have mainly
just tweaked area temps tds with this update and no other
changes planned attm.

Prev disc...

high pressure will build over the region today producing mostly
sunny skies and much less humidity. Highs will range from the
mid 70s north to the mid 80s south.

Short term 6 pm this evening through 6 pm Wednesday
High pressure will shift off to the southeast overnight with
return flow bringing a return of humidity to the region. After a
mostly clear evening expect variable clouds after midnight along
with patchy valley fog. Lows will range through the 50s across
much of the forecast area with lower to mid 60s in the far
south.

Showers and thunderstorms will be likely on Wednesday as a warm
front lifts into southern new england ahead of an approaching
shortwave. Expect increasing shear during the day with
widespread thunderstorms breaking out in the afternoon and
persisting through the evening hours. Shear profiles will be
sufficient for rotating storms and some super cells especially
during the late afternoon as better dynamics advect in from the
west. SPC has entire forecast area in a marginal risk with a
slight risk from western maine through a good portion of new
hampshire. Damaging winds... Hail and isolated tornadoes will be
possible with these storms. High temperatures will range from
the upper 70s to mid 80s.

Long term Wednesday night through Monday
Unsettled weather to start the long term period then several
days of fantastic weather.

Wednesday night a warm front will be lifting north. Showers and
a few thunderstorm will be prevalent through the night as the
front treks north. High precipitable water will result in some
localized heavy rain. The cold front will move around noon on
Thursday. Showers are possible and with isolated thunder on
Thursday. Dewpoint temperatures will slowly fall during the day
Thursday. Friday will begin the much cooler and drier air with
highs in the 60s north and 70s south with dewpoints in the upper
40s to mid 50s. There is the chance of a shower in the mountains
as the trough moves overhead.

This weather holds sway over the forecast area through Tuesday
as surface high pressure and a ridge aloft keep the heat and
humidity away.

Aviation 15z Tuesday through Saturday
Short term...VFR today through tonight. Areas of MVFR
ceilings vsby in showers and thunderstorms on Wednesday.

Long term... Expect plenty of MVFR ifr Wednesday night into
Thursday morning in showers and thunderstorms. Thursday expect
mostlyVFR except MVFR in passing showers. FridayVFR with local
MVFR in a shower at hie during the afternoon. Saturday expect
vfr conditions.

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.
