The area of low pressure and cold front generating the snow and much colder temperatures will swing through mid-afternoon which will rapidly drop out temperatures in a span of a few hours.
Roads will be wet from the rain and will quickly freeze, causing a flash freeze and making roads icy. Rain will also quickly transition over to snow and we could see periods of very heavy snow.
