Synopsis
Weak high pressure will build south of the region today and will
hold over the region tonight and Wednesday as low pressure
passes well offshore. A complex area of low pressure will
approach from the southwest Wednesday night and Thursday and
will slowly move northeast through southern new england and the
gulf of maine Thursday night and Friday. High pressure will
build in from the west Friday night and Saturday. A cold front
will drop south through the region Saturday night and Sunday.

Near term /through today/
Low pressure will depart off to the east early on today. As a
westerly flow develops early on this morning, the low clouds,
fog, and drizzle will be shunted offshore. The result should be
a partly sunny day with highs in the 70s at most locations with
light winds.

Short term /tonight through 6 pm Wednesday/
As a short wave trough amplifies over the lower oh valley
tonight and Wednesday, deep layer ridging will develop over new
england. This should allow for another nice day on Wednesday as
low pressure passes well to our south. It may be a bit more
cloudy, but highs should reach into the 70s once again.

Long term /Wednesday night through Monday/
High pressure will hang on through Wednesday night as low pressure
over the ohio valley slowly begins to lift northeast. After a
partly cloudy evening expect high and mid level clouds to over-
spread the region from the west. Low temps will range from the
mid 40s north to the mid 50s south.

Complex area of low pressure will continue to lift toward new
england on Thursday. Best forcing remains south of the region
through the day along a developing warm front. Will likely stay
close to sb numbers for pops but expect any showers to be light
and spotty. Increasing onshore flow will likely bring ocean
stratus into the picture in southern zones during the afternoon
and evening. High temps away from the coast should reach the
mid to upper 60s with upper 50s to lower 60s along the coast.

Low pressure becomes vertically stacked south of new england
Thursday evening and will slowly drift northeast overnight.

Looking for occasional periods of rain overnight but nothing
too heavy. QPF will only amount to a quarter inch or less
through daybreak Friday. Lows overnight will be fairly uniform
across the forecast area with most locations bottoming in the
lower to mid 50s.

Low pressure will move northeast through the gulf of maine and
into the maritimes on Friday. Looking for rain for much of the
day before precipitation tapers to showers late Friday afternoon.

Models in fairly good agreement on QPF with most areas picking
up a a half to 1 inch of accumulation with some higher amounts
in mid coast maine. Highs on Friday will once again range through
the 60s with coolest readings along the coast.

Low pressure will pull away from the region Friday night as a
shallow surface ridge builds in from the west. Looking for
clearing skies during the evening hours. Lows overnight will
range from the mid 40s north to the lower 50s south.

High pressure will build south of the region on Saturday bringing
a mix of Sun and clouds to southern and central zones. A backdoor
cold front settling into northern maine will bring increasing
clouds and a chance of afternoon showers to northern zones. Highs
on Saturday will range from the mid 60s to lower 70s.

Backdoor front will continue to settle south Saturday night and
Sunday. After a chance of evening showers in the north... Not
looking for much more than variable clouds overnight. Lows will
range through the 40s north and lower to mid 50s south.

Frontal boundary will stall over southern new england on Sunday
as high pressure builds south from canada. This boundary may be
the focus for clouds and afternoon showers in southern new
hampshire and southwest maine as an onshore flow increases north
of the front. Expect highs in the 60s to near 70 but dropping
back into the lower 60s along the coast in the afternoon.

Aviation /07z Tuesday through Saturday/
Short term... Ifr conditions early this morning should improve to
vfr by around 13z. TheseVFR conditions should continue for most
terminals through Wednesday.

Long term...

vfr Wednesday night and Thursday. Ifr/lifr ceilings and vsby
Thursday night and Friday... Improving toVFR Friday night.VFR
Saturday.

Marine
Short term... Conditions should remain below SCA thresholds today
through Wednesday.

Long term...

Fire weather
Warmer and drier weather is expected today and Wednesday with rh
values generally in the 40s. Renewed chances for rain will
arrive for Thursday and Friday.

Tides/coastal flooding
Highest astronomical tides of the season will likely result in
some minor coastal flooding at the time of high tide Thursday
night and again on Friday night.

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.
