...Snow wraps up across Northeast/Mid-Atlantic Coast today while Lake
Effect snow picks up...

...Heavy rainfall returns to Pacific Northwest...

...Frigid Arctic airmass spreads into Eastern U.S. today...


A quick-hitting band of snow should wrap up in the Mid-Atlantic this
morning, but linger along the Northeast/southern New England Coast into
late this afternoon before finally moving offshore this evening. In its
wake, a very cold and dry arctic airmass will move into the Eastern third
of the country. Surface high pressure over the Upper/Middle Mississippi
Valley will support high temperatures in the single digits. Extreme Cold
Warnings are in effect for portions of east-central Illinois into
west-central Indiana. Highs in the teens may tie or break numerous records
in the Ohio Valley today. Arctic air arrives over the Southeast tonight,
with freeze warnings hoisted for portions of southern Georgia and northern
Florida. Cold air remains locked in over the East into Monday before
temperatures begin to moderate on Tuesday. Cold northwesterly flow over
the Great Lakes will generate moderate to heavy snowfall across downwind
areas through Monday evening. The Lower Great Lakes may receive 6-12
inches, with isolated higher amounts, by Tuesday morning.

Upper ridging in the West will support above average temperatures across
the region today before expanding east into the Plains on Monday. Highs
will rival existing records for many parts of the West through mid-week.

Heavy rain returns to the Pacific Northwest today, beneath a deep
upper-level low and waves of surface low pressure systems. The heaviest
rainfall will occur on Monday and Tuesday, when a strong occluded system
moves through the region. A slight risk of excessive rainfall leading to
flash flooding is in effect for western Washington and northwestern
Oregon, due in part to sensitivities from the most recent heavy rain event
from last week. Some heavy snow may impact the highest elevations of the
northern Cascades as well.
