Of course, the biggest question on everyone’s mind is, “how much snow will fall?”

Here’s what we know:

  • Rain to snow Sunday night into Monday
  • Snow showers Monday night into Tuesday
  • A mild weekend leading into Monday will mean warm road temperatures, so snow will not accumulate as quickly to start
  • Roads will become icy late Monday into Tuesday as temperatures drop
  • Winds increase late Monday-Tuesday with some gusts up to 30-40mph possible
  • Wind chills will be in the teens/20s for Tuesday

As for snow totals, that’s where it gets a little tricky. Sunday night will be mainly raining with some light snow mixing in by dawn Monday. A battle between rain and snow will occur Monday morning before switching completely to snow as temperatures drop during the day. Snow showers will continue through Tuesday along with gusty winds.

Early snowfall estimates indicate less than an inch southwest of Dayton, one to three inches around Dayton, higher amounts to the northeast.

This storm system is still a few days out, so the forecast will likely shift in the days ahead, but for now, this is what we know.
