Synopsis
A warm front will cross the area later tonight into Wednesday
morning. A cold front will cross the region early Wednesday
night. High pressure will build across the region Thursday into
Friday.

Near term through Wednesday
Midnight update... Rain continues across the area, mainly light
over the north with heavier rain downeast. Temperatures look
good with increasingly humid air pushing north across the area.

No major changes this hour.

Looking forward to Wednesday late afternoon evening and the
severe weather threat, there is some concern of a decent high
shear low CAPE qlcs event. Can't rule out an isolated tornado
mainly in western parts of the forecast area.

Previous discussion...

classic warm frontal conditions will exist tonight into
Wednesday morning as the cool canadian high is overrun by a much
warmer and moist air mass from the ohio river valley. Clouds
will thicken and lower this evening and precip will arrive from
west to east late this afternoon into the evening. Gusty winds
will subside this evening with the beginning of precip and the
stability of the approaching warm front. The heavier precip with
the warm front will be towards the coast in concert with a very
strong h925 LLJ with speeds up to 65 kts. Around an inch could
fall towards the coast tonight. This heavier precip is currently
moving towards connecticut and will track towards the coast
later this evening. Have added mention of heavy rain along the
coast for tonight. Reviewed the threat of thunder with the warm
front and it deserves consideration with an anomalous theta-e
ridge and dew points hitting the mid to upper 60s. Elevated
convection could fire off an h925 thermal ridge near the warm
front as it moves north Wednesday morning, but have not included
in the forecast yet. Have included a mixture of light rain,
drizzle and fog with the warm front into the morning when the
dew points surge into the mid to upper 60s. After morning warm
frontal precip, light rain and drizzle won't amount to much
until the cold front arrives late day. Not expecting much
surface heating with the cold front as it'll take much of the
day just to eradicate the warm frontal inversion... And then
there'll be copious h850-h925 moisture to keep an overcast over
the area. Warm advection alone will produce highs near 70f on
Wednesday as h925 temps surge towards 20c. When the cold front
arrives late day in northwest zones, guidance is still showing
some marginal sbcape, deep moisture and a lot of shear to
organize a line of storms... Enough to warrant mention of a
chance of thunderstorms with gusty winds. The primary concern
will be some gusts towards 40 kts and locally heavy downpours in
northwestern aroostook for late afternoon into the early
evening. Convective gusts to 40 kts in combination with leaves
on the trees could produce damage.

Short term Wednesday night through Friday
A cold front will cross the region early Wednesday night. The
cold front will reach northern maine Wednesday evening, then
exit the downeast coast during the early morning hours. Rain
will occur in advance of the front, with heavier showers and
possible thunderstorms along the front. A low level jet will
cross the region in advance of the front. Any heavier showers or
thunderstorms could help mix these winds to the surface
producing strong wind gusts. High pressure will begin to build
across the region later Wednesday night in the wake of the cold
front with decreasing clouds. High pressure will then cross the
region Thursday into Friday with partly cloudy mostly clear
skies. Temperatures will be at near normal levels
Thursday Friday.

Long term Friday night through Tuesday
A cold front will cross the region Friday night into Saturday,
though the exact timing of the front is still uncertain. The
front could bring a chance of showers to mostly the north and
mountains. High pressure is expected early Sunday, with another
cold front possible late. This front could bring another chance
of showers to mostly the north and mountains. High pressure will
cross the region Monday. Low pressure will approach from the
great lakes later Monday then cross the region Tuesday with a
chance of rain. Near normal level temperatures are expected
Saturday. Slightly below normal level temperatures are expected
Sunday through Tuesday.

Aviation 04z Wednesday through Sunday
Near term: conditions will rapidly deteriorate to ifr CIGS this
evening. Vlifr CIGS are possible by later tonight and fog will
probably effect bhb later tonight well into Wednesday. Llws is a
threat for bgr and bhb tonight. Heavy rain will likely affect
bhb tonight. Embedded thunderstorms are possible very late
tonight into Wednesday morning with a warm front. CIGS will stay
ifr much of Wednesday morning and barely reach MVFR for the
afternoon. A very strong cold front will move into the nw
portion of the state later Wednesday with NW wind gusts up to 40
kts and isolated thunderstorms.

Short term: ifr lifr conditions are expected in advance of the
cold front early Wednesday night, with improving conditions late
in the wake of the cold front. Gusty winds are possible with any
stronger showers or thunderstorms in advance of the front. Low
level wind shear could also be a concern in advance of the
front. GenerallyVFR conditions are expected across the region
Thursday into Sunday. However, occasional MVFR conditions are
possible across mostly the the north and mountains later Friday
into Saturday.

Marine
Near term: low end gale conditions look likely for tonight.

Winds aloft will be very strong, but most won't mix down due to
the stability with the approaching warm front. The warm front
will introduce very humid air over the cold waters that will
likely lead to areas of fog by later tonight through Wednesday.

Winds and seas will remain elevated during Wednesday such that a
small craft advisory will be necessary after the gale warning
concludes. Seas will actually increase through the day
Wednesday.

Short term: small craft advisory level winds seas are expected
Wednesday night into early Thursday. Small craft advisory level
seas will then persist into Thursday. Winds seas are expected to
be below small craft advisory levels Thursday night through
Friday. Visibilities will be reduced in rain and fog Wednesday
night, along with the chance of a thunderstorm through early
morning.

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.
