pressure moves in from the west on Monday. Low pressure moves in
Tuesday.

.NEAR TERM /THROUGH FRIDAY NIGHT/...
Key Messages
-Scattered to isolated snow showers on Friday could produce a
 quick inch of snow and low visibilities
-Breezy Friday night could bring some cold wind chills

The frontal boundary continues to exit to the NE while the wrap
around moisture from the occlusion moves into the region. For
tonight, skies will be generally cloudy some some clearing
through the night. Light onshore winds will keep temps in the
20s. For Friday, winds become more SW and breezy as the pressure
gradients tighten around the low. Upper air model soundings
indicate a period in the afternoon where instability values will
increase. The concern will be the potential for isolated to
scattered snow showers that could produce localized amounts up
to 1 inch in a short time. This will also reduce visibilities,
making for dangerous conditions for travelers. For Friday night,
some isolated showers could last into the early night. Since
winds will continue to be breezy and temps will decrease into
the low 20s, cold wind chill temps into the teens are possible.

.SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/...
Key Messages

-Light snow event possible Sunday mainly northern areas

A mainly dry west to northwest flow is expected Saturday as low
pressure near Labrador continues to slowly exit and high
pressure to out southwest builds east. Afternoon high
temperatures will range from the lower 30s north and mid to
upper for th Bangor region and Downeast, which is just a bit
below normal for this time of year.

Saturday evening begins mainly clear followed by increasing mid and
high level clouds later Saturday night. Lows will range from the
lower teens north to around 20 for the Bangor region.

Low pressure will track from the Great Lakes region early Sunday and
then quickly into Quebec province Sunday night. Warm advection
aloft results in precipitation developing from west to east
early Sunday. Along the coast expect precipitation to begin as
mainly rain but snow elsewhere. Precipitation then changes
rather quickly to all rain by later Sunday afternoon south of a
Dover Foxcroft to Houlton line. The precipitation across eastern
Aroostook could end as a rain snow mix before ending later
Sunday night.

A low level jet will also bring the potential for some stronger
winds to the Downeast coast later Sunday afternoon into Sunday
evening, possibly nearing advisory conditions.

.LONG TERM /MONDAY THROUGH THURSDAY/...
Key Messages

-Snow possible Tuesday and Tuesday night
-Below normal temperatures

Low pressure intensifies as it tracks through Labrador during
Monday. A few snow showers not totally out of the question
across the north on Monday but will keep it mainly dry at this
point and time. A tightening pressure gradient around the low to
our northeast and potential for a deepening mixed layer could
result in a rather gusty wind during Monday.

Monday night will be mainly clear and dry resulting in
radiational cooling. Lows across northern areas may bottom out
near the zero degree mark.

The attention on Tuesday will turn to low pressure tracking
northeast from the mid atlantic region. This system has the
potential to bring accumulating snow to the region Tuesday and Tues
day night. This will ultimately depend on how far north the
lows tracks which is still uncertain this far out in time.

The aforementioned low tracks northeast away from the region on
Wednesday. Another frontal system may approaches by Thursday.

Afternoon highs on Monday will be near normal and then below
normal through the middle of next week.
