Monday through Tuesday, the center of this sprawling, early spring storm will spin slowly northeastward over the eastern Great Lakes to the Saint Lawrence Valley.
Snow north and west of the storm center will lay down snowfall of 3-6 inches in a swath over northern Michigan into Ontario Canada. Slushy pavement will slow travel in areas such as Detroit. However, a far greater area from the Great Lakes south to the Tennessee Valley and southern Appalachians will see snow showers, mostly with no accumulation.
Strong thunderstorms will shift across the southern Appalachians to the mid- and southern Atlantic coast on Monday. From the Delmarva to northeastern Florida, a few severe thunderstorms could spark damaging winds and hail.
Northward from the mid-Atlantic, soaking rains will fan out over the Northeast and into eastern Canada, leaving rainfall of 1-2 inches over a wide area as of Tuesday morning. Urban and small stream impact will be felt along the I-95 corridor.
Along the New England coast, gales will be possible late on Monday and especially on Monday night.
