...Major winter storm winds down over the Northern Plains today...

...Isolated severe weather and flooding possible for parts of the
Northeast today...

states as East Coast and Deep South warm up...

...Active period continues from the Rockies to the Pacific Northwest as
low elevation rain and mountain snow impact the region...

A deep upper-level trough will rotate a potent surface low pressure system
through the eastern half of the country through Friday. Tuesday's major
winter storm will begin tapering off in North Dakota and Minnesota today.
A few more inches of snow are possible. Blizzard Warnings remains in
effect from eastern Montana into western and central North Dakota, where
the combination of snow and strong wind gusts will produce dangerously low
visibilities, with significant blowing and drifting of snow. Some snow
squalls are possible across portions of central Minnesota and into
northern Wisconsin this afternoon. Travel will remain very hazardous
today, with some additional power outages possible. Road conditions should
improve by Friday.

Showers and thunderstorms will persist within the warm sector of this
dynamic winter storm as a cold front continues to surge eastward through
the East Coast today. Isolated instances of severe weather and flash
flooding are possible. The Storm Prediction Center has issued a Slight
Risk (level 2/5) for severe thunderstorms over portions of the I-95
corridor extending from the Philadelphia metro area to western
Massachusetts today. Gusty winds and marginal hail are possible with the
strongest thunderstorms. Heavy rainfall may develop along the central Gulf
Coast this morning as the aforementioned cold front slowly through the
region.

Temperatures will continue to remain well below average for much of the
Northwest and Northern Plains, as frigid air settles in on the backside of
the departing winter storm this weekend. High temperatures will be between
20-30 degrees below average for much of the Northern Plains, as places
struggle to make it above freezing today and Friday. Much of the East
Coast will experience a second day of well above average temperatures
before the cold front sweeps through on Friday and moderates the airmass a
bit. Highs will be in the 70s and 80s across the eastern seaboard today.
The southern tier states will begin warming up again on Friday as an
approaching system pulls warm air into the region.

A meandering stationary front in the West and arriving low pressure system
will generate additional coastal/low elevation rain showers as well as
mountain snow for much of the Pacific Northwest and Northern Rockies over
the next couple of days. Parts of the northern Sierra and Northern Rockies
will pickup another 6-12 inches of snow by Saturday morning. Elevated fire
weather risks continue over portions of the Central/Southern Plains
through Friday.
