Snow has arrived across southern and southwestern Ohio as of lunchtime. It will continue in these areas for the rest of the day while also spreading farther north and east over time. It will snow heavily at times this afternoon and evening in particular. 

Snow will continue to fall tonight into tomorrow across most of the state. There will be periods tonight when the snow is light; it could even stop for a little bit in spots. It's during this time that some sleet and/or freezing rain could fall in southern Ohio.

Bottom line: the heaviest and longest duration snowfall with this storm will occur in central and southern parts of the state. In general, locations near and south of I-70 will see a solid 6-12 inches of snowfall.

For those north of I-70 it's going to be a lower impact event. Totals here will range from nearly nothing around Toledo and Cleveland to 2-4" in areas just north of I-70 like Sidney, Bellefontaine, Delaware, and Cambridge.

Snow will end through the day Monday as the system departs to the east. The rest of the week features a little bit of lake effect snow potential and random snow showers at times — mainly on Wednesday.

There is also another system that could bring some light snow to the state Friday into early Saturday. There's plenty of time to watch this and fine tune its potential impacts, so stay tuned as we progress through the week!

Otherwise it will be a very cold week. High temperatures will mainly be in the 20s with overnight lows in the single digits and teens. Wind chills will be even colder at times. This will likely be the coldest stretch of winter so far for most of Ohio.
