Synopsis
High pressure will remain across region through the first half
of the week. This will provide dry weather and seasonably cool
temperatures. A cold front will move in Wednesday night and
cross the area Thursday with a chance of showers. High pressure
builds quickly by on Friday with another front arriving by
Saturday morning.

Near term through today
Sfc high pressure will stay put across new england today
providing for another fair weather day with temperatures mainly
in the 70s. Strengthening upper level low pressure just off to
our east will continue to move northeastward as well, keeping us
on the dry side of it. This will allow for mostly sunny skies,
although a period or two of bkn clouds may occur. A seabreeze is
expected to move onshore this afternoon.

Short term tonight through 6 pm Tuesday
High pressure at the sfc remains across the region tonight. This
will set the stage for another radiational cooling night with
valley fog expected late.

Not much change for Tuesday as high pressure very slowly slips
off to the southeast. Aside from some increasing cirrus, mostly
sunny conditions are expected. Highs will be a bit warmer than
today's, reaching the mid 70s to around 80 at many locations.

Long term Tuesday night through Sunday
Broad upper trough over central north america will gradually
shift eastward with time. The core of the upper low tracks
northeast well north in canada while the lower trough axis moves
into new england Wednesday night into Thursday along with a
surface cold front. Another spoke of energy rotates through the
upper trough sending another cold front into new england Friday
night.

Tuesday night could be another good radiational cooling night,
though there is the potential for increasing clouds to put a cap
on the cooling overnight. Wednesday sees a southerly flow ahead
of the approaching cold front. Moisture return with this front
is rather paltry by summer standards and the best lift will be
well to the north. In fact, the front loses some of its push
as it arrives Wednesday night and takes through Thursday to
finally clear the area. We should expect scattered showers
mainly in northern areas, but it will not amount to much total
rainfall. One complicating factor is tropical low that gets
pulled up the east coast on Thursday. When this moisture gets
pulled into the frontal boundary it will provide a more
significant rainfall, but this looks like it will happen to our
east.

Surface high pressure axis crosses the area on Friday with the
next cold front arriving quickly from the northwest Friday
night. Again the moisture return with the front is quite
lacking, so don't expect much precipitation other than a stray
shower. Dry high pressure builds in behind it. In fact, if gfs
materializes dewpoints could be falling into the 30s which could
set up some cool nights for the first few days of september.

Aviation 06z Monday through Friday
Short term through Tuesday ...VFR. Localized ifr conditions
are likely between 08-12z at kleb and khie Monday and Tuesday morning
in stratus and fog. Otherwise clear withVFR conditions.

Afternoon seabreezes at the coast.

Long term... Should stayVFR through Wednesday, though some
morning fog is possible in the valleys. A cold front crosses the
area Wednesday night into Thursday with a few showers as it does
so.

Marine
Short term through Tuesday ... Onshore flow continues through
Monday with gradually building seas. Winds should stay below 25
kt but seas will likely reach 5 ft tonight into Tuesday morning
for the open waters south of casco bay. SCA for seas around 5
ft remains in effect.

Long term... High pressure over the gulf of maine Tuesday gives
way as a cold front approaches from the west and tropical low
pressure moves north through the western atlantic on Wednesday.

The low should pass to the east of the gulf of maine on
Thursday. High pressure quickly crests over the east coast on
Friday with another cold front arriving by Saturday morning.

Gyx watches warnings advisories
Me... None.

Nh... None.

Marine... Small craft advisory for hazardous seas from 11 pm this
evening to 8 am edt Tuesday 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.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
