Lake-effect snow is a good bet, if all the parameters congeal, behind the arctic front late Monday into Tuesday. Significant accumulations are possible in the most persistent snow bands.
Sandusky and Richland counties are under a Level 1 Snow Emergency, which means roadways are hazardous with blowing and drifting snow.
It's worth noting that plenty of areas in West Michigan and the lake-effect snow belts of northwest lower Michigan will be dealing with lake-effect snow too, so be sure to travel cautiously if traveling west today. Gusty winds could also cause some visibility issues on the roads. Wind chills near or below 0° for much of the day. Snow will spread from south to north beginning around 4 p.m. Sunday and lasting until 6 a.m. Christmas Day. Most of this snow will fall by early afternoon. Temperatures tonight drop to the single digits with wind chills near -10.
We may have some wind chill advisories issued at some point today.
