Precipitation types will vary this weekend, likely starting with snow Saturday morning, shifting to rain Saturday afternoon and night, then switching back to snow as the cold air moves in on Sunday afternoon.

Northern New Jersey could get 2 to 4 inches of snow before a switch to a wintry mix. Heavy rain is expected Sunday.

A powerful and deadly winter storm that has been slamming the Plains and Midwest Wednesday morning moved into Chicago, Detroit and the Great Lakes during the afternoon.
