Synopsis
High pressure will build in from the north today providing for a
cooler and drier day than Saturday. Low pressure will approach
from the southwest later tonight and Monday and will deliver
cooler temperatures and the likelihood of rain. Conditions will
gradually improve by Tuesday night and Wednesday as high
pressure moves in. A cold front approaches late in the week.

Near term until 6 pm this evening
High pressure will build in from the north today providing fair
and cooler weather. High temperatures will mainly be in the 70s
today with a few lower 80s possible. Onshore flow developing
during the afternoon should knock temperatures along the coast
down into the 60s by early evening. Skies will be partly sunny,
with an increase in clouds expected later in the day as a waa
regime gets going.

Short term 6 pm this evening through 6 pm Monday
A short wave trough will approach early on tonight and should
aid in spreading rain across nh after midnight. This rain
(mainly light) will then spread across maine on Monday. Not a
very nice july day to be had with temperatures mainly in the
60s, with a prolonged period of 50s possible where the rain is
early and steady during the day.

Long term Monday night through Saturday
The week begins with an upper level trough in place over the
northeast united states. The trough and associated surface low
will move east of the region late Tuesday with high pressure
building in for Wednesday. Another upper low will approach on
Thursday pushing a surface cold front through the region.

Monday night low pressure will move through the gulf of maine
with a secondary surface low trying to spin up along the st.

Lawrence river. Still expect a region of widespread rain around
the low center in the gulf o maine with a secondary maxima
through the st lawrence valley. Some periods of heavy rain are
possible on Tuesday morning with more widespread light rain.

Along the coastal plain of maine look for some drizzle as
saturated low levels and northeasterly flow continue while the
dynamics split to the east and west. It'll be a damp night
across the region with rain, drizzle, fog and lows in the upper
50s.

This damp weather will continue through Tuesday morning with
the skies finally starting to clear late Tuesday allowing
temperatures to rebound into the mid 70s in parts of f the
area. High pressure builds back into the region on Wednesday as
the upper low move off to the northeast.

The overall pattern will continue to be quite progressive as
the next upper level trough dives south of the canadian prairies
by Thursday. This forcing aloft will provide good support for a
cold front which will move through late afternoon Thursday. With
temperatures warming to the upper 70s to near 80 ahead of this
front and dewpoints near 60s expect the afternoon timing to be
more than enough to set off a line of thunderstorms.

Friday high pressure returns to end the week.

Aviation 07z Sunday through Thursday
Short term through Monday ...VFR conditions are expected today
through much of tonight. However, MVFR conditions are expected
to arrive Monday morning as rain moves into the
region... Possibly as early as tonight across nh.

Long term... Low pressure will move through the gulf of maine
Monday night into Tuesday brining widespread rain drizzle and
ifr conditions overnight. Conditions will begin to improve on
Tuesday and return toVFR with just some valley fog possible on
Tuesday night. Wednesday will return toVFR. A front will cross
the region on Thursday with thunderstorms possible at all
terminals.

Marine
Short term through Monday ... Northeasterly flow early this
morning may gust around 25 kt for a short time prior to 12z off
the southern me coast and seacoast of nh. Will forgo SCA at this
time because it will be marginal and brief. Otherwise, sca
conditions may begin to develop late Monday afternoon with low
pressure to the south of the region.

Long term... Northeast winds will increase on Monday night into
Tuesday ahead of a low moving through the gulf of maine. A small
craft may be needed in this time period for the outer waters. Widespread
fog and rain is expected as the low moves through. Winds and
seas will subside by Tuesday with high pressure building in for
Wednesday.

Gyx watches warnings advisories

Nh... None.

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.
