High pressure exits southeast of Nova Scotia overnight, while

Low temperatures across northern/central portions of the
forecast area will generally range through the single digits
above and below zero dependent on cloud cover. Low temperatures
across interior Downeast areas will generally range from zero to

Discussion...

Tomorrow weak southerly return flow develops around the high
turns winds southerly across the area. Highs will climb into the
low to mid 20s north, mid to upper 20s Central Highlands, around
30F for Bangor and upper 30s Downeast. Cannot rule out some
isolated snow showers with the slight increase of boundary layer
moisture and mainly cloudy skies. A weak surface trof will
develop along the Downeast coast and be the focus for some light
precipitation of either rain or snow till sunset and turn
mainly to snow. Not expecting much precipitation but as the sun
sets and temperatures cool expecting potential for slick travel
along the Route 1 corridor east of Machias to Eastport region.
Up to 1 inch of snow is possible.

Saturday night a very weak wave, barely a cold front will cross
the state. Skies will break up to partly cloudy skies with
temperatures falling back into the teens for most locations.
Exception of single digits in the North Woods and St. John
Valley and 20s along the Downeast coast. Light SW winds will
shift back W as a weak surface wave pushes through the area.

.SHORT TERM /SUNDAY THROUGH MONDAY/...
An Arctic front will push across the north during the predawn hours
Sunday, possibly with some isolated snow showers. The front will
reach the coast around late morning. Arctic air will follow with
clearing by midday Sunday followed by some increasing high clouds
from the south late Sunday afternoon ahead of a weak shortwave.

A weak weather system rounding the bottom of a trough centered over
the Eastern Great Lakes will approach Sunday night bringing
increasing clouds. A small low will track into the Gulf of Maine
late Sunday night spreading light snow across the area, mainly
Downeast, where 1 to 2 inches of snow may fall by early Monday
morning. A bit of light snow will likely reach northern areas early
to mid morning Monday, mainly as a function of lift out ahead of the
shortwave trough crossing the area. The upper trough and surface low
will quickly continue to the east Monday afternoon followed by
clearing Downeast and partial clearing over the north. Gusty winds
will likely result in patchy blowing snow Monday afternoon as Arctic
air surges in.
&&

.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
Monday night will be clear to partly cloudy and very cold with lows
by Tuesday morning dipping just below zero over the north and into
the single digits Downeast. High clouds may begin to increase over
the north ahead of a weather disturbance tracking from Ontario
into Quebec.

Clouds will increase Tuesday and a bit of light snow is
possible Tuesday night as the weather disturbance moves across.

Our focus on Wednesday will be on a new low approaching from the
west. Current forecast models disagree on the track of this system
with the GFS carrying the low to our northwest which would bring
snow or mix changing over to rain and a south wind. The ECMWF,
however, tracks the low into the Gulf of Maine late Wednesday into
Wednesday night favoring snow across the region.
