Synopsis
High pressure will remain across the region into Wednesday. A
cold front will approach later Wednesday then cross the region
Thursday.

Near term through tonight
1230pm update...

high pressure overhead, leading to a sunny day with low
humidity, seasonable temperatures, and very light winds. Just a
few fair weather cumulus forming in the heating of the day in
northern maine. No changes needed to the forecast.

Previous discussion...

the powerful upper and surface ridges will continue to deliver
strong subsidence with little cloud cover and no precip through
tonight. The blocking ridge evolves to a rex block during the
forecast period. The closed upper low to the south has become a
more dynamic feature in recent model runs with cyclogenesis
occurring well south of nova scotia later tonight. The only
potential consequence in the forecast area could be some cirrus
spinning around the closed low into the downeast region very late
tonight. For today, a nominal increase in 850mb temps will
deliver highs several degrees higher than yesterday, especially
in the southern half of the forecast area which won't be
affected by cloud cover today. In spite of a rather deep mixed
layer this afternoon, winds aloft are light and surface winds
will remain light all day. Clear skies and light winds carry
into Sunday night with another strong radiation inversion. In
spite of an even deeper inversion, lows won't be quite as cold
as this morning's readings. Valley fog and steam fog over
relatively warmer lakes rivers will return later Sunday night.

Short term Monday through Tuesday night
Surface high pressure will remain across the region Monday
through Tuesday, then begin to move east Tuesday night. At the
same time, an intensifying ocean low will track toward eastern
nova scotia. Aloft, an upper low will move east across nova
scotia, eventually capturing the surface low. High pressure will
keep generally mostly clear skies across the region Monday
through Tuesday night. However, the surface upper low across
the maritimes could wrap clouds back toward eastern portions of
the forecast area Monday night into Tuesday. Patchy valley fog
is also possible across the region Monday night. Temperatures
will be at near normal, to slightly above normal, levels
Monday Tuesday.

Long term Wednesday through Sunday
A cold front will move east across quebec province Wednesday
while another ocean low intensifies south of the gulf of maine.

Expect increasing clouds in advance of the cold front later
Wednesday. The cold front approaches the region Wednesday night
while the ocean low tracks toward nova scotia. Expect increasing
shower chances across the region Wednesday night in advance of
the cold front. The cold front will cross the region Thursday.

Uncertainty exists Thursday regarding the extent to which
moisture from the ocean low is drawn north across the region in
advance of the cold front. Have kept a chance of showers across
the region Thursday. However, if more significant moisture is
drawn north more extensive showers or a steadier rain are
possible. Showers should end later Thursday night with building
high pressure, which will then cross the region Friday. A cold
front should approach later Friday night with a chance of
showers across mostly the north and mountains. The cold front
will begin to cross the region Saturday, though the exact
timing is still uncertain. Expect a chance of showers with the
cold front. Near normal, to slightly above normal, level
temperatures are expected Wednesday Friday Saturday. Near
normal, to slightly below normal, level temperatures are
expected Thursday.

Aviation 18z Sunday through Friday
Near term:VFR into this evening with light winds. Patchy valley
fog late tonight could lead to MVFR or perhaps ifr at TAF sites
typically more susceptible to fog... For example kpqi, khul, and
kbgr. Kpqi and khul had the fog Sunday morning, but not right
now kbgr. However, kbgr will have lighter winds tonight than
last night, so believe fog more likely tonight at kbgr than last
night.

Short term:
Monday through Wednesday... GenerallyVFR. However, variable
conditions are possible with any late night valley fog.

Wednesday night through Thursday... Mvr ifr with showers.

Improving conditions Thursday night.

Marine
Near term: conditions remaining below small craft.

Short term: winds seas will remain below small craft advisory
levels Monday through Tuesday night.

Car watches warnings advisories
Me... None.

Marine... None.

Near term... Foisy mcw
short term... Norcross
long term... Norcross

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.
