- Lake effect showers into the weekend then dry and milder

The Great Lakes region is between an upper low across the NE CONUS and a sharp upper ridge to the west as an omega block is in place across North America. The resulting cyclonic flow will continue through Saturday before the blocking breaks down and heights rise by Sunday.

Lake effect rain and snow showers will gradually end this weekend as the ridge flattens and moves east across the region, with dry and mild conditions into mid-week. Return flow moisture and a low moving across southern Canada could being showers by the end of the week.
