The primary low pressure center is forecast to move northeastward
to the Upper Great Lakes throughout the day Tuesday and into
Canada by Wednesday. The front will move south as a cold front on
the west side of the low into the Southern Plains while on the

across the Midwest and Great Lakes Region. Snow is forecast to
continue to the northwest of the low over the Northern Plains
through early Tuesday afternoon and the Upper Midwest into Tuesday
evening. Snow is also forecast to continue over the Central
Rockies, Central Great Basin, and into the Southwest. The heaviest
snow is expected over portions of central and southern Minnesota
into northern Wisconsin, where additional snowfall of 6" + is
likely and isolated totals up to a foot are possible. In addition,
freezing rain is forecast as warm air aloft lifts northward with
the warm front over the Midwest and Upper Great Lakes. Ice
accumulations of 0.1" + are possible from southern Wisconsin
through central Michigan, with totals greater than 0.25" forecast
over portions of central Lower Michigan under the Ice Storm
