Snowy stretch continues with lake effect Wednesday, Canadian Prairies system Thursday

Cold high pressure over Northwestern Ontario and a low pressure system over the Ohio Valley work hand in hand to maintain lake effect snow production over Upper Michigan overnight through Wednesday -- moderate to heavy snowfall possible in southern counties near the Lake Michigan shore, then over the Central U.P. as the wind flow shifts from the northeast.

Snow showers gradually taper off Wednesday late afternoon west through east. But, a system from Central Manitoba dives towards the Western U.P. late Wednesday, looking to spread at least moderate snow showers over the region Thursday. Under a northerly jet stream, a clipper system brings widespread snow and chillier air into the U.P. over the weeekend -- with high temperatures ranging in the 10s-20s.
