Synopsis
High pressure will move east on today. Low pressure will
approach from the west tonight and cross the region Sunday
through Monday.

Near term through tonight
Update...

high pressure will continue to move east of the region this
afternoon. Cloud will be on the increase today well in advance
of low pressure to the west. Expect partly sunny skies today
with near seasonal high temperatures this afternoon.

Previous discussion
strong high pressure will approach from the west and
crest over the region mid day today then move east into the
atlantic. Low pressure will approach the region from the
southwest today and tonight. This approaching system will first
spread clouds across the state later today and this evening.

Snow is then expected to overspread the region late tonight into
Sunday morning.

Short term Sunday through Monday night
Next winter storm wl be on our doorstep Sun mrng as ridge axis
shifts east into canada. Models hv trended slower with onset of snow
acrs the area and hv delayed pops until just aft 12z. By this time
parent low wl hv mvd into WRN great lakes as upr low currently ovr
nm ejects northeast thru the early part of the weekend.

By 00z Mon secondary low wl hv dvlpd down arnd casco bay with a
strong LLJ preceding it. H9 winds of 50-75kts wl lkly bring high
wind gusts along the immediate coast and outer islands Sun aft and
evng.

As warm air gets pumped in expect snow to mix with and then change
to rain in the afternoon acrs downeast and spreading north to the
penobscot vly in the evng. Expect that most of the snow in downeast
wl fall fm Sun morning into the late aftn hrs bfr switching over.

Areas north of a dover-danforth line wl lkly stay all snow
throughout the event although cannot rule out a snow sleet line in
that transition area somewhere.

Wl transition winter storm watches over to warnings but delay the
start time from 12z Sun to 15z. Winter wx advisory wl be issued for
the bangor region, northern hancock and central washington with 3-5
inches of snow expected on the front end.

Sfc low passes into nb after 06z Mon with contd snow showers, mainly
across the north with an addn'l 1-3 inches expected. Cold advection
in wake of sfc low and FROPA wl allow for strong mixing Mon aftn and
ovrngt. This wl lkly lead to areas of blowing snow acrs NRN areas,
especially for north-south roads. Wl lkly need wind headlines on mon
at some point.

Long term Tuesday through Friday
Pressure gradient rmns tight thru Wed mrng before high pressure
builds over the northeast. Latest med range guidance conts to show
discrepancies on possible mid-week system with GFS the only guidance
bringing a clipper thru Wed night. Wx looks fairly quiet thru the
end of the week. Temps wl moderate but rmn blo normal.

Aviation 15z Saturday through Wednesday
Near term: update... ExpectVFR conditions today through much of
tonight.

Short term: conditions deteriorate to ifr Sun morning as snow
overspreads the area from southwest to northeast. Snow may mix
with or transition to rain for downeast terminals Sun afternoon
with MVFR restrictions expected early Sun night before becoming
vfr. Northern terminals will likely see ifr or lifr into Monday.

MVFR will be possible into Wed as low stratus effects northern
sites. In addition gusty west winds Mon afternoon through tue
night may lead to low vsbys in blowing snow across the north.

Marine
Near term: will use the NAM to initialize winds. For waves: a
bi-modal wave spectrum has persisted for the last 24 hours with
the primary wave system consisting of long period southeasterly
swell (9-11 seconds) and a secondary off-shore wind wave. During
the last few hours the wind wave have has become the primary
wave system as the longer period swell has been slowly
subsiding. Later tonight combined seas are expected to subside
to below 2 feet. A new southeasterly fetch will develop on
Sunday. Total water level: storm surge guidance continues to
verify well so will gust keep a slight positive anomaly of +0.10
along the coast. Expect a storm surge of 1.5 to 2.0 feet by late
Sunday with strong southeasterly winds. The maximum surge is
however expected to occur around the time of low tide. A very
low negative surge (1.5 to 2.0 feet) is expected by late Monday
as strong off-shore winds develop. In bangor ice continues to
produce a large positive anomaly at low tide so will adjust for
this in the base tide anomaly.

Short term: gale force winds can be expected ahead of a low
pressure system crossing downeast sun-sun night. Strong cold
advection in it's wake will move in Mon afternoon, leading to
wind gusts > 50kts, thus have issued a storm watch Mon afternoon
and Mon night. Winds likely diminish before storm force after
06z Tue with gale force winds expected into Wed morning. Expect
seas will increase to between 8-12 feet ahead of the low
pressure system Sun afternoon and Sun 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.
