A strong cold front will cross the region this morning. High
pressure will then build across the region through the weekend.
.NEAR TERM /THROUGH TONIGHT/...
Update...Hrly temps were adjusted to meet the latest conditions
w/readings dropping off considerably from this morning. Colder air
will continue right into tonight w/wnw winds 20-30 mph gusting to
40 mph. Gusts to 45 mph expected across higher terrain. Radar
showed some isolated/scattered snow showers across northern Maine
this morning pulling out attm. The latest NAM and RAP showed some
more activity later this morning into the afternoon. This looks to
be mainly across western and northern areas. Vsby could be reduced
to less than 1 mile combined w/the winds and this could lead to
travel issues. Will issue a Special Weather Statement to address
this after 10 AM.
Previous Discussion... A strong cold front will cross the region
this morning. High temperatures will occur early today then fall
in the wake of the cold front. Otherwise, expect partly cloudy
skies with isolated to scattered snow showers across the north and
mountains today. Generally expect little or no snow accumulation.
However, locally greater accumulations could occur beneath any
more persistent snow bands. Mostly sunny skies are expected across
Bangor and Downeast areas today. A strong pressure gradient will
produce gusty winds today, with west to northwest winds generally
gusting up to around 40 mph. Locally stronger gusts could occur
across higher terrain areas. High pressure will build east toward
the region later tonight. Gusty winds will persist into the
evening then begin to diminish overnight. However, the winds will
remain strong enough to produce dangerous wind chills of 20 below
zero to 30 below zero later tonight across northern portions of
the forecast area. Have issued a Wind Chill Advisory for northern
portions of the forecast area tonight into Saturday morning. High
temperatures will occur early today ranging through the 20s to
lower 30s north, with upper 30s Bangor and interior Downeast with
around 40 to the lower 40s along the Downeast coast. Low
temperatures tonight will range from around 5 below zero to around
10 below zero north, to around zero to 5 above zero Bangor and
