.DISCUSSION...
KEY MESSAGE 1...Strong westerly winds today could lead to some
isolated power outages. Also, the strong wind coupled with the
colder temperatures will lead to dangerous wind chills in the
mountains today.

KEY MESSAGE 1 DESCRIPTION...
Strong westerly winds are currently increasing as a low-level
jet of strong winds aloft associated with a departing low moves
over the area. The strongest winds are currently expected
around mid-morning today before gradually tapering off this
afternoon as the strong low pressure system exits the area.
Currently expecting gusts to between 40 and 50 mph over the
higher terrain across the north, with up to 65 mph possible at
the highest summits. A Wind Advisory is in effect for areas
including and north of Millinocket and Greenville.

Over interior Downeast and the Bangor region, expect westerly
wind gusts between 30 and 40 mph but below wind advisory
criteria. It is likely that significant leaf loss will occur
across the region, especially where peak foliage has been
reached. Gusty winds could also lead to some isolated power
outages.

With the colder airmass moving in, the strong winds will lead
to dangerously cold wind chills in the mountains through
tonight. Katahdin will have wind chills in the teens even in
the middle of the day today. Hikers should be prepared for
winter conditions.

KEY MESSAGE 2...Frost expected Downeast tonight with low
temperatures approaching freezing.

KEY MESSAGE 2 DESCRIPTION...
High pressure building in behind the departing low pressure
system should lead to clear skies overnight which in combination
with decreasing winds should allow for strong overnight cooling.
Temperatures are expected to dip into the low to mid 30s tonight
over the interior Downeast where the growing season is still
active. Widespread frost is likely and thus a Frost Advisory
has been issued. For coastal Downeast, expect a more patchy
frost with temperatures in the mid to upper 30s, especially
further inland. Did not have enough confidence yet to issue a
Frost Advisory here due to some concerns about winds staying
elevated which would counteract the overnight cooling.
