A negative phase of the Arctic Oscillation is allowing very cold air to spill into the Miami Valley and stay through the middle of December. This means any storm systems or disturbances this week will have temperatures cold enough to support snow, Zontini said.
WHEN YOU MIGHT SEE SNOW THIS WEEKEND:
A piece of upper-level energy will enter the Miami Valley Saturday and bring the chance for snow showers. The timing looks to impact the morning and afternoon hours.
Meteorologist Kirstie Zontini said there isn't much moisture so accumulations will be light — likely less than an inch.

Looking at the past, the Dayton International Airport usually sees the first measurable snow — a tenth of an inch or more — at the end of November. This year we got a little snow around that time.
The first inch of snow at the airport is usually around December 7.
Since temperatures will stay so cold over the week, the chance this weekend for some slick spots on the roads will be something to watch for late Saturday afternoon and evening.
