...Powerful winter storm to produce significant impacts across parts of
New England and coastal Mid-Atlantic/Northeast on Saturday...

...Below-average temperatures will expand across the eastern third of the
country this weekend before moderating next week; Great Plains and
Mississippi Valley warm up into next week...

...New system to bring rain and heavy snow to the Pacific Northwest and
Northern Rockies beginning Sunday...

An area of low pressure, currently off the Carolina coast, will rapidly
intensify today as it makes its way up the eastern seaboard. Heavy snow
and powerful winds will spread from the Mid-Atlantic coast to the
Northeast coast throughout the day. The combination of heavy snow rates
and strong winds will produce dangerous blizzard conditions across
portions of the Mid-Atlantic and New England coasts, from Virginia's
Eastern Shore to eastern Maine, where Blizzard Warnings are in effect.
Travel in these areas will be nearly impossible today due to whiteout
conditions. Total snowfall accumulations greater than 12" are expected
along much of the Northeast coast with local maxima greater than 24"
across eastern Massachusetts including the Boston metro area. Winter Storm
Watches and Warnings are also in effect from the coasts farther inland
where accumulating snowfall is also likely. Strong damaging winds will
lead to scattered power outages. Very cold temperatures will spread across
the eastern third of the country on the backside of the departing
Nor'easter. This may exacerbate an already dangerous situation for those
without power/heat. The snow and wind will come to an end across northern
Maine on Sunday.

Elsewhere, Freeze Watches and Warnings are in effect for much of the
Florida Peninsula for tonight. Much of the state will remain mostly clear
and frigid tonight with a chance of scattered to isolated falling iguanas
due to the subfreezing temperatures. The Great Plains and Mississippi
Valley will warm up through the beginning of the work week. Upstream from
the Nor'easter, an upper-level impulse will generate windy surface
conditions across the Central Plains today. That paired with relatively
dry air will lead to an elevated Fire Weather threat. An emerging low
pressure system will bring rain and heavy snow to the Pacific Northwest
and Northern Rockies on Sunday and continuing across the Northern Rockies
into Monday. A closed upper-low may generate scattered showers and
thunderstorms across southern Texas and the western Gulf coast Sunday
night into Monday.
