COLUMBUS, Ohio (WTVN) -- Temperatures on Tuesday topped 70 degrees in parts of Ohio, but many of those same areas are dealing with snow today.

A Winter Storm Warning is up for much of northern Ohio through Wednesday. Some areas could see more than 8 inches of snow. Several counties have issued level 3 snow emergencies, closing roads to all but emergency travel.

"If you don't have to be out, stay home," said Defiance County Sheriff Dave Westrick who issued a level 3 snow emergency Wednesday morning.

He said several factors go into the decision to increase snow emergency levels, including talking with the county engineer, road crews, and driving the roads himself.

"It isn't just a snap decision," he said.

Lucas County, home to Toledo, is among those at the highest snow emergency level. That forced the Hollywood Casino to close.

Auglaize County Sheriff Al Solomon says most roads in his county, just south of Lima, are snow-covered with blowing and drifting snow causing problems.

"We have plenty of salt in our district to be able to handle this storm," said Amanda McFarland, spokesperson for ODOT's District 12 in northeastern Ohio.

She says the goal is to get major highways cleared and back up to speed within two hours of the snowfall ending.

Central and southern Ohio are expected to pick up anywhere from a couple inches to a trace of snow. The biggest issue could be the timing of the snow, which is expected to make the commute back home this afternoon a bit tricky.
