...Locally heavy snow to spread across the high terrain of the Northern
Rockies and Northwest...

...Snow possible for parts of the Upper Mississippi Valley and Great Lakes
region Monday into Tuesday...

Temperatures will rebound to above normal values across most of the
country for the start of the week. Rain and snow showers are possible for
much of the Northeast on today. Snow will spread across portions of the
Pacific Northwest, Intermountain West, Northern Rockies and into western
fringe of the High Plains over the next few days. Favored upslope areas
could have locally heavy snow accumulations, which may reach 2 feet prior
to Tuesday. Lower elevations across Idaho and western Montana may also
experience lighter snowfall amounts. Snow is also forecast to move across
the eastern Dakotas and the Upper Mississippi Valley Monday evening
through Tuesday. This part of the country may pick up a few inches of snow
before midweek. Light showers can be expected for portions of the South,
Southeast, Tennessee Valley and into the Mid-Atlantic ahead of approaching
fronts while there will be shower chances for Arizona and New Mexico ahead
of a churning upper-level low.
