Synopsis
High pressure will exit across the maritimes today. Strong low
pressure will cross the region Sunday, drawing a cold front
across the region.

Near term through tonight
Update...

high pressure will begin to exit across the maritimes this
afternoon. At the same time, low pressure will intensify across
the great lakes drawing a warm front toward the region. Cloud
cover will increase across the region through the afternoon in
advance of the warm front. Afternoon high temperatures will
range from the lower to mid 30s north, to around 40 interior
downeast with lower 40s along the downeast coast. Have updated
the forecast to adjust for current conditions along with
afternoon temperatures and cloud cover.

Previous discussion...

another round of wintry weather is expected to move in this
evening and overnight.

Warm air advection begins in earnest tonight as the low begins to
lift into the saint lawrence river valley, allowing a swath of
precipitation to spread from west to east overnight. The warm air
will initially spread northward by lifting over the colder air at
low levels, resulting in a mix of snow, sleet, and freezing rain,
mainly along and north of a dover-foxcroft to danforth line.

Temperatures will fall a bit early this evening, but then they will
rise overnight as the warm air is able to replace the cold air at
the surface. As such, the wintry mix will gradually change to just
plain rain from south to north, with all but the upper st john
valley seeing all rain by daybreak. Both snow and ice accumulations
will be light, less than 1 inch and less than 1 tenth of an inch,
respectively. Therefore, only minor travel impacts are expected.

However, if the cold air sticks around longer than currently
anticipated, the ice and snow accumulations could increase. Will
allow later shifts take a look at the incoming hi-res near term
models before making any decisions on headlines.

Short term Sunday through Monday
A strong area of low pressure near montreal Sunday morning is
expected to track to the north of the gaspe peninsula by 00z
Monday. The CWA will be in the warm sector Sunday morning and
into the first part of the afternoon with periods of rain.

Colder air begins to sweep in from the west mid to late
afternoon as the rain ends from the south. Much colder air pours
into the region Sunday night on a gusty west wind. Isolated
snow showers are possible to the north and west of the katahdin
region. Any areas of standing water will freeze Sun night, and
temperatures Monday afternoon will only recover to the mid 20s
north to the low 30s in the greater bangor region. There will be
a gusty west wind that will add to the chill. It will likely
remain mostly cloudy in the north with a few flurries and partly
sunny toward the coast.

Long term Monday night through Friday
Overall fairly quiet weather for thanksgiving week. A weak
frontal boundary could produce a rain or snow shower late tue
night or Wednesday morning, but there will not be much moisture
with this front. There remains uncertainty as to whether a wave
develops along the front to the south of the area and clips the
region with another period of rain or rain changing to snow
Wednesday night. Much of the guidance keeps this feature
offshore, but it bears watching. The 00z ecwmf now brings
precipitation to nearly all of the CWA (mostly rain, ending
perhaps as a period of snow), and the GFS keeps all of the
precipitation well south and east of the region, and the
canadian just grazes the coast. The 00z ECMWF has little
support from its ensembles members. Any potential system bears
watching, but until there is better agreement will stick with a
model consensus and nothing higher than chance pops. Colder air
filters into the region behind the front, and thanksgiving
should be a dry day with some breaks of sunshine and highs from
the upper 20s in the saint john valley to the mid to upper 30s
downeast. A tough and developing surface low may bring a chance
of snow to mainly northern areas Friday, but there is not great
model agreement, and some models would keep the area mainly dry.

Aviation 16z Saturday through Wednesday
Near term: occasional MVFR ceilings are possible across northern
areas this afternoon. Otherwise,VFR conditions are expected
across the region this afternoon through early tonight.

Conditions will then deteriorate overnight as a mix of snow,
sleet, freezing rain, and rain spread from west to east 00z-12z
sun. Expect all terminals to be ifr by 06z or shortly
thereafter. Bgr and bhb will remain plain rain through the
period, while the other terminals will see snow mixing with
sleet and freezing rain, then change over to plain rain from
south to north 06z-12z.

Short term: lifr to ifr in rain Sunday will improve to MVFR and
eventuallyVFR at the downeast terminals by late Sunday. Improvement
to MVFR expected at the northern terminals toward evening.

Predominately MVFR Sun night at the northern terminals with brief
ifr in any snow showers. VFR expected downeast Sun night.

PredominatelyVFR Mon and tue, but patchy MVFR ceilings possible at
times in the north.VFR expected wed, although conditions may
lower to MVFR late in the day at the downeast terminals.

Marine
Near term: winds seas will be below small craft advisory levels
this afternoon through early tonight. Small craft advisory
conditions will then develop overnight, with gale force wind
gusts possible late. Visibilities will be reduced in rain and
fog overnight.

Short term: gales likely on the waters Sunday and have issued a
gale watch. Gales possible into Monday with small craft advisory
conditions likely to persist into Tuesday.

Climate
The first measurable snowfall (0.8") of the season was observed
at caribou Friday, 11 17. It was the 4th latest measurable
snowfall on record behind only 1994, 2010, and 2016.

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.
