Miami Valley , Whitewater Valley, and the I-71 corridor of Ohio/Indiana:
Clouds increase tonight this combined with a Southerly flow, temperatures will stay in the middle 20s. Tomorrow winds will be Southerly bringing clouds with a slight chance of a rain/snow shower early , then mild air will move North ahead of a cold front that will move in overnight tomorrow night. This front will over run moisture that will move North from our developing winter storm. First a wintry mix will allow for light ice/sleet accumulations late tomorrow night and early Sunday. Sunday the mix will change to snow and become heavy at times Sunday evening and night before tapering off Monday morning. Ice accumulations near US-35 will be on the order of 0.05 to 0.1 of an inch. Snowfall accumulations could be 6 to 12 inches with 12 inches closer to I-70. If this system moves South a bit a narrow 10 to 14 inch band of snow could effect the region. Any adjustment North could mean more significant ice accumulations and lesser amounts of snow.
Colder air will once again filter in behind this storm and dominate most of next week.
