Synopsis
Arctic high pressure will build south from quebec today into
tonight. High pressure will cross the region Thursday then exit
across the maritimes Friday. A cold front will cross the region
Friday night through early Saturday.

Near term through tonight
1235 pm update...

skies hv clrd ovr SRN areas and gradually beginning to clr acrs
ern aroostook this afternoon. Based on latest trends hv had to
raise maxes by 3-5 degrees areawide. No other chgs needed attm.

Previous discussion...

the norlun feature along the hancock county coast will slide
southward in the coming hours with snowfall ending. This is in
response to a upper trough from quebec pivoting southward. The
focus then turns to a bitterly cold and dry arctic high. Under
the center of the high early this morning, synoptic reports and
metsat indicate surface temps less than 30 below... And perhaps
approaching minus 40f. As the high builds, cold air advection
will limit today's highs to near 10f in the saint john valley
where h925 temps will be around minus 20c this morning. This
cold air sinks towards bangor and the coast today where highs
will be close to this morning's readings. There is some h925
moisture with the cold advection which will generate a thin
layer of cloud cover in northern zones today. Can't rule out a
few inconsequential flurries from this layer this morning...

mostly in upslope areas of the western and northern mts. Much
more important will be the gusty north winds that will produce
wind chills below zero in northern zones through the day... And
single digits southward to the coast. With clouds dissipating
and winds decreasing to calm tonight, the stage is set for the
coldest night of the season in many locations. Strong pressure
rises, the trajectory of the high and the building upper level
high all give confidence to winds going calm for the entire area
after midnight. It'll be the sixth night in a row with zero or
less at caribou and the first of the season at bangor. For lows
tonight, started exclusively with bias-corrected guidance and
then undercut that data. Wouldn't be surprised to see some
readings less than -30f in the allagash by Thursday morning. The
record low at caribou is -20f which will be tough to beat given
our hilltop location, but should be attainable at nearby
presque isle in the valley. The record low at bangor is -17f and
our forecast is only around zero.

Short term Thursday through Friday night
High pressure will cross the region Thursday, then exit across
the maritimes Friday. Mostly clear skies are expected Thursday
through Thursday night. Cloud cover will increase Friday in
advance of an approaching cold front. Models are in better
agreement drawing the cold front across the region Friday night
through early Saturday, though the exact timing is still
uncertain. Expect a chance of light snow across northern areas
Friday night, with the chance of a light wintry mix across the
remainder of the forecast area. Temperatures will be at below
normal levels Thursday. Near normal level temperatures are
expected Friday.

Long term Saturday through Tuesday
The cold front will cross the region early Saturday. Expect a
chance of snow or a wintry mix across northern and central
portions of the forecast area early Saturday in advance of the
cold front, with a chance of mostly rain downeast. Precipitation
will end in the wake of the cold front with high pressure
building toward the region later Saturday. High pressure will
build across the region Saturday night through Sunday with
generally partly cloudy skies. Low pressure is expected to
track south and east of the region later Saturday through
Sunday, keeping precipitation south and east of the region. A
disturbance could cross the region Monday with a chance of snow
showers. High pressure should then build toward the region
Tuesday. Above normal level temperatures are expected Saturday.

Near normal, to slightly above normal, level temperatures are
expected Sunday Monday. Near normal level temperatures are
expected Tuesday.

Aviation 18z Wednesday through Monday
Near term: outside of MVFR CIGS thru 22z this afternoon north
of hul,VFR expected at all terminals next 24 hours. Gusty nw
winds will diminish late this afternoon evening. There could be
some temporary restrictions to vis by sunrise on Thursday as an
inversion will trap smoke in valleys.

Short term: generallyVFR conditions are expected across the
region Thursday into Friday, though MVFR conditions could begin
to develop across northern areas later Friday. MVFR ifr
conditions are expected across the region Friday night through
early Saturday. Conditions will improve later Saturday in the
wake of a cold front, withVFR conditions expected Saturday
night into Sunday. Expect a chance of light snow across northern
areas Friday night, with the chance of a light wintry mix
across the remainder of the region. Expect a snow rain mix
across northern areas early Saturday in advance of the cold
front, with mostly rain downeast.

Marine
Near term: will leave the times of the small craft advisory in
place as winds have just started to pick up at the eastern maine
shelf as a compact low in the gulf of maine moves further
offshore. These winds will spread eastward along the washington
county coast in the coming hours. Seas will remain around 3 to 4
feet.

Short term: conditions are expected to be below small craft
advisory levels Thursday into Friday. Small craft advisory
conditions are then possible later Friday into Friday night.

Visibilities will be reduced in rain 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.
