DAYTON — UPDATE on Sunday 12/14 @ 5:41 a.m.:
The Winter Weather Advisory has been cancelled for the entire region. A Cold Weather Advisory remains in effect for the entire region until 11 a.m. Monday.
INITIAL REPORT:
Good evening, everyone! Meteorologist Nick Dunn here with you on a busy and snowy Saturday.
This system will bring a solid amount of snow to start the weekend, but my concerns then turn to dangerously cold temperatures for Sunday into Monday.
A Winter Weather Advisory is in effect for Auglaize, Butler, Clark, Clinton, Champaign, Darke, Miami, Logan, Mercer, Montgomery, Preble, Shelby, and Warren counties in Ohio. It also includes Randolph and Wayne Counties in Indiana.
A Cold Weather Advisory is in effect for the entire region until 11 a.m. on Monday
While snow slowly tapers off later tonight, gusty winds will take this fluffy snow and blow it around to cause road issues into Sunday morning.
The forecast remains unchanged as 3-6″ of snow is likely for everyone when you look at the map! A few reports to around 7 inches are possible south of I-70 in particular where some banding of snow has been rather frequent and longer lasting.

Futurecast shows snow tapering off a bit by 8:00 PM, and by then temperatures are cold enough where salt is less effective. We will find the snow continuing to slowly add up through about 10:00-11:00 PM when all that is left are flurries. Windy conditions will make secondary roads and untreated surfaces slick through the remainder of the nighttime into Sunday morning.

A Cold Weather Advisory is in effect from tonight through Monday Morning. This is issued when the wind chills drop to -10 degrees or colder. We definitely have that on tap for Sunday and Monday mornings.
The coldest wind chills will exist Sunday morning for everyone! Single digit air temperatures with wind chills of -10 to -20 degrees are likely.
Monday morning is marginally better, but still dangerous as frostbite can set in within 30 minutes on exposed skin when wind chills drop below zero. Improvement will be noticed by afternoon with highs in the lower 20s. Stay safe!
