Washington Headline: Post Bomb cyclone’ blasting East Coast before polar vortex

This is the 48 hr forecast - 955 mb - very low pressure

a bomb is: of a rapid intensification of a cyclone (low pressure) with surface pressure expected to fall by at least 24 millibars in 24 hour. This one is dropping about twice that fast.

Forecast here in Maine is 8- 14 inches of snow tomorrow and wind gusts to 35 mph, 45 mph gust out at the coast. Saturday the cold weather comes in, forecast is -18 F. Hope the power doesn’t go out.

Marine
Short term… A strong storm will pass through the gulf of
maine tonight bringing a large area of hurricane force gusts
to the outer waters. Casco bay and penobscot bay remain at
storm force as some of the strong gusts are likely to mix down
even along the shoreline.

Long term… Cold and windy conditions will likely lead to
freezing spray through Sunday morning. Winds gradually diminish
and finally fall below advisory levels at least briefly on
Sunday, but will increase again on Monday as another trough
moves through.
