Heavy lake effect snowfall

The cold mixed with a low pressure system moving through the Northeast is transitioning precipitation into snowfall in Michigan, Wisconsin, Illinois, Indiana, Ohio, Pennsylvania and New York.

The "warmer" waters are helping to enhance the moisture moving over them and causing the increased snow totals downwind of the lakes.
