...Moderate to heavy rain possible across parts of the Northeast tonight...

...Heavy lake-effect snowfall downwind of the Great Lakes through early
this week...

...Below average temperatures common for much of the country for at least
the next few days...

Low pressure tracking up the East Coast tonight and cold air surging into
the eastern half of the Nation by early this week will set the stage for
unsettled and impactful weather for parts of the country. Moderate to
locally heavy rain is likely to swing northward from the northern
Mid-Atlantic coastline to southern New England tonight, with snowfall
possible in the elevated terrain of northern New England. This wave of
precipitation will continue pushing northward on Monday throughout Maine.
Winter Weather Advisories have been issued from northern New Hampshire to
northern Maine, where up to 6 inches of snowfall is possible.
Additionally, a separate area of precipitation dampening northern Florida
this afternoon is expected to exit the region tonight and lead to mostly
dry conditions across the Sunshine State on Monday.

As cold air rushes into the eastern U.S. over the next few days, favorable
westerly winds and warm lake temperatures will allow for heavy lake effect
snowbands downwind of the Great Lakes. The highest snowfall totals are
likely downwind of lakes Erie and Ontario. Snow accumulations upwards of
15 to 20 inches are possible where Lake Effect Snow Warnings have been
issued. Lake effect snow is also possible downwind of Lake Michigan and
Lake Superior, with up to a foot of snow possible across the U.P. of
Michigan. Residents and visitors traveling within the Great Lakes region
are advised to remain weather aware and prepare for drastically changing
road conditions depending on the location of snow showers and heavy
snowbands.

Elsewhere, dry and cool weather is anticipated throughout the rest of the
CONUS as high pressure dominates. Showers may begin to enter parts of
central California on Wednesday as a low pressure system nears the West
Coast. Below average temperatures will stretch across much of the country
on Monday and confine to the eastern U.S. on Tuesday. Lows into the single
digits and teens are forecast for the central/northern Plains and Upper
Midwest on Monday, with blustery and winter-like temperatures found
throughout the Ohio Valley, Mid-Atlantic, and Northeast on Tuesday.
