A clipper-type low pressure system will track through the Great Lakes today, passing north of Ohio tonight. As it passes by it will drag a cold front eastward across the region tonight. Ahead of the front, milder air will boost high temperatures into the 40s today. Scattered rain showers are possible across northeastern Ohio this afternoon.
Tonight, once the cold front moves to our east, colder air will change the rain showers to snow showers. Any snow accumulations tonight should be light.
On Friday, colder air will continue to settle across the region. A disturbance currently over North Dakota, will track southeastward into the lower Great Lakes late tonight and across Ohio on Friday. This system will bring a period of enhanced snow showers to the area Friday with some light accumulations possible. It will also bring a reinforcing shot of colder air.
Once the disturbance passes to the east of the area Friday night, winds will shift to the northwest and conditions will become more favorable for lake effect snow. Snow bands will organize southeast of Lake Erie across the primary and secondary snow belts where several inches of snow could accumulate.
Late Friday night or early Saturday, yet another disturbance will track southeastward across the area. This will likely disrupt the lake snows for a time, and provide widespread snow showers to the entire area. Behind that feature, the winds will align out of the northwest once again with more lake effect snow possible Saturday night.
Additional accumulations are possible Saturday and Saturday night, especially across the snow belt areas.
All of the activity will finally wind down Sunday morning as high pressure builds across the region.
