Low pressure system moved over the Great Lakes region Saturday evening, resulting in warm air advection in the mid-levels. Deep warm nose led to sleet, and then a sleet/freezing rain mix early Sunday morning in the north and Central Highlands region. Very cold low-level layer helped precipitation to refreeze. Roughly an inch or so of snow fell in the north, alongside an inch to an inch and a half of sleet by Sunday morning. Impacts were mainly just a messy clean up period.
