Current Radar, Conditions

Snow will continue to wrap in behind Xanto on Monday from the Great Lakes to the Ohio Valley and Appalachians as the storm moves slowly northeastward. Ice or snow changing to rain is forecast across parts of northern New York and northern New England.

The storm system will also produce heavy rain along the Northeast Interstate 95 corridor on Monday. This could lead to localized pockets of flash flooding.

Monday night, light snow or rain changing to snow may affect areas from Michigan to West Virginia, western Pennsylvania and Upstate New York.

Bands of light snow or rain mixed with snow may linger into Tuesday across the interior Northeast.

Any additional accumulations will be light through Monday evening with most areas seeing a coating to perhaps a few inches.
