Low pressure will pass well north of the area today. A cold front trailing this system will move west to east across the eastern Great Lakes today, accompanied by snow showers and a reinforcing surge of colder air.
Snow showers will gradually diminish across the area early tonight with some partial clearing possible. After midnight, the cold air across the region will deepen sufficiently to promote the development of some limited lake effect snow across the snow belt. Accumulations should be light.
On Saturday, lake effect parameters will become much more favorable as another disturbance approaches from the northwest and synoptic moisture increases. Snow showers will increase across the entire area with the heaviest snow likely across the snow belt areas east of Akron and Cleveland.
The disturbance will move east of the area Saturday night. Shifting winds during the evening could disrupt the lake effect snows briefly, but once this feature moves to our east, winds will settle back to the northwest and lake snows will reorganize. Some locations across the snow belt could pick up several inches of snow.
The lake effect snow will persist into Sunday morning. Then high pressure will build across the area bringing an end to this activity.
