Synopsis
Low pressure will shift east into the maritimes overnight. High
pressure will build in from the north on Wednesday and will hold
over the region on Thursday. A warm front will lift northeast
through the region Thursday night and early Friday followed by a
strong cold front Friday night. High pressure will build over
the area Saturday and will shift east on Sunday.

Near term tonight
After a busy day tonight will be much more tame. A S WV trof and
attendant front will push thru the region. At the surface a cold
surge is moving down the st. Lawrence valley... And down from the
county towards downeast me. This will continue to creep towards
our forecast area thru the evening and overnight. Some low
clouds are possible along the coast as the cooler NE flow
arrives... While inland may seem some fog this evening while it
remains clear. Most likely to see the longest period of clear
would be the ct river valley... Where I have areas of fog in the
forecast. Elsewhere is more uncertain... As clouds move in from
the ne.

We will also see continued shower activity along the approaching
cold front... But the majority of these will likely dissipate
after dark.

Short term Wednesday through Wednesday night
Lingering trof overhead Wed will provide a focus for some
afternoon clouds and scattered showers... Especially early on.

Generally used the multi-model consensus blend for pop... But
precip will be relatively hit and miss. In NE flow temps will be
much cooler... With readings hanging in the 60s. In the far
sw... Near een... Temps may run at 70... While closer to moosehead
lake will struggle into the 50s. Wed night widespread 40s and
50s are expected.

Long term Thursday through Tuesday
High pressure will crest over the region on Thursday producing a mix
of Sun and clouds and temperatures slightly below normal for a
change. Expect highs to range through the 60s from north to
south.

High pressure will shift east Thursday night as a warm front approaches
the region from the southwest. Will see increasing clouds
during the evening hours and showers will move into the region
from the southwest after midnight. Highest pops will be found in
the better dynamics to the north and west of the forecast area
with rainfall amounts in the .25 to .50 inch range through mid
afternoon Friday in the mountains. Lows overnight will range
from the mid 40s north to the mid 50s south.

Rain will gradually taper to showers from southwest to northeast Friday
morning but expect skies to remain mostly cloudy as abundant
low level moisture lingers behind the warm front. Even though
850 mb temps support upper 70s to lower 80s... Clouds will hold
high temps in the mid 60s to mid 70s from north to south.

A cold front will push in from the west Friday evening bringing
another round of showers and some thunderstorms... Mainly after
midnight. Good forcing along the front and marginal instability
will produce scattered convection ahead of this boundary. Very
strong shear with the associated shortwave may produce isolated
severe cells with wind damage being the main threat. Pwat's
ahead of the front will MAX out in the 1.5 to 2.00 inch range
contributing to heavy downpours and possible downbursts in
heavier cells. Expect the front to quickly push offshore by
daybreak Saturday taking any lingering shower activity with it.

Lows will range from the upper 40s north to the lower 60s in the
south.

Saturday will feature breezy and much cooler conditions as high
pressure builds in from the west. Expect variable clouds in the
morning to give way to mostly sunny skies in the afternoon.

High temps will generally range through the 60s from north to
south.

High pressure will crest over the region Saturday night producing
mostly clear skies and light winds. Low temperatures will range
from the mid 30s in the north to the upper 40s in the south.

High pressure forecast to shift east on Sunday with increasing
onshore flow setting up. This will produce a mix of Sun and clouds
in southwest zones and mostly sunny skies elsewhere.

Temperatures will top out below normal ranging from the mid 50s
in the north to the mid 60s in the south.

Models diverge significantly for the latter periods of the
forecast with timing of the next cold front and associated
precipitation... So have generally stuck close to sb numbers.

Aviation 19z Tuesday through Sunday
Short term... Still some areas of broken MVFR CIGS as drier air
filters in from the n. Will likely see all terminals go toVFR
eventually. After sunset the NE flow will bring cooler air down
the coast... And models forecast ifr CIGS to move down from
rkd aug thru pwm to psm. I am not totally sold on widespread ifr
or lower... Especially as quick as models like the hrrr show
it... But I have included sct007 CIGS to show the potential.

Winds will likely be calm enough to see some valley fog in the
ct river valley... So leb and hie have lifr tonight. Lingering
trof overhead into Wed will lead to some widely scattered
shra... But not likely enough at any terminal to include in the
taf.

Long term...VFR Thursday. Areas of MVFR ifr ceilings developing
Thursday night and persisting through Friday.VFR Saturday and
Sunday.

Marine
Short term... Ne surge is forecast to work down the coast
tonight. Model guidance suggests some gusts above 25 kts and
seas building to 5 ft... So I have issued a SCA into early wed
afternoon.

Long term... Sca's likely Friday through Saturday.

Gyx watches warnings advisories
Me... None.

Nh... None.

Marine... Small craft advisory from 2 am to noon edt Wednesday 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.
