...Widespread precipitation will continue to develop ahead of an Arctic
airmass surging into the eastern U.S. on Monday...
...Heavy snows expected downwind of the Great Lakes...
Another blast of Arctic air surging through the Nation will drop
temperatures across the central and eastern U.S. early this week. At the
leading edge of the frigid airmass...moisture getting pulled from the Gulf
and Atlantic will fuel widespread precipitation ahead of a cold front
crossing the Appalachians on Monday. Heavy rains with embedded strong to
severe thunderstorms are expected in the Southeast...while a wintry mix of
snow...sleet...and freezing rain will be possible over portions of
interior New England. The cold front and associated precipitation should
clear the Eastern Seaboard by early Tuesday...however...cold Arctic air
ushering in over warmer lake waters will set the stage for heavy snow
bands downwind of the Great Lakes.
An upper ridge centered over the West Coast will keep weather quiet in the
western U.S...but a Pacific system inching towards the coastline could
bring precipitation into Northern California by the middle of the week.
