.NEAR TERM /THROUGH TODAY/...
12:27AM Update...No changes. Just minor tweaks to the ongoing
forecast based on observational trends.

Previous Discussion...
High pressure will move east of the region tonight. At the same
time, low pressure tracking northeast through Quebec province
will begin to draw a warm front across the region late. Expect
partly/mostly cloudy skies across the forecast area tonight. The
warm front will cross the region early Tuesday. A cold front will
then approach northwest portions of the forecast area late
Tuesday afternoon. Expect mostly cloudy skies north, partly
sunny Downeast, Tuesday. Could also have scattered afternoon
rain showers across northern areas. Low temperatures tonight
will occur during the early morning hours, then begin to slowly
warm overnight. Low temperatures tonight will range from 10 to
around 15 north, to the lower to mid 20s interior Downeast with
mid to upper 20s along the Downeast coast. High temperatures
Tuesday will range from the lower to mid 40s north, to the mid
to upper 40s Downeast.

.SHORT TERM /TONIGHT THROUGH THURSDAY/...
Low pressure system to the northwest in Quebec brings a
potential for some precipitation Tuesday evening into Wednesday
morning. Warm front moves past the area Tuesday, and by Tuesday
night, cold front begins to approach Maine from west to east.
Temperatures stay above freezing until frontal passage late in
the evening, causing temperatures to quickly go below freezing.
As a result of this, precipitation begins to change over to
snow showers. Expecting less than an inch in snow total accumulations.
With temperatures forecast to stay well below freezing Tuesday
night, any standing water could freeze, causing untreated
surfaces to become slick, especially for Wednesday morning
commute. Low temperatures on Tuesday night into Wednesday
morning are forecast to be in the teens up north, and 20s south
of Mt. Katahdin. There is some model indication for some
shortwave kinks to develop over central Maine Tuesday evening
into the nighttime, with some favorable lift conditions, so may
monitor for some localized heavier showers to occur. Pressure
gradient stays over the area Tuesday morning, leading to some
gusty winds Tuesday night into Wednesday.

Ridging moves in on Wednesday into Thursday morning. High
temperatures forecast to be in the 20s/30s throughout the
forecasting region. Weak low pressure expected to bring some
snow showers Wednesday night into Thursday night. Currently, not
forecasting anything over an inch in snow totals. Could be some
clearing up north overnight, which could lead to radiational
cooling. Lows could be at or around zero in the north, and
teens/low 20s Downeast.

&&

.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
Weak low pressure system moves away from Maine by late Thursday
night with snow showers pushing away around midnight. Ridging
then builds in on Friday due to a high pressure system moving
through the area.

Main concern in the long term is a longwave low-pressure system
moving through the middle of the country that moves northeast
through Michigan into Canada, indicating good chances for
precipitation to fall. High pressure that moves out on Friday
parks in the Atlantic, causing a tightening pressure gradient
over Maine, which could lead to gusty winds. Warm air gets
advected in ahead of the system, causing seasonably warm
temperatures next weekend with highs currently forecast in the
40s and 50s. Most models continue to show support for rain to
fall late Saturday into Monday. Temperatures currently forecast
to go below freezing again Monday night as a coastal low
pressure system moves along the coast, which would transition
rain to snow everywhere. Current concern for impacts is going to
be a potential for ice jams and rising river levels from snow
melt on top of rainfall. On Tuesday, as temperatures fall below
freezing, could be another concern for slick travel conditions.
