Miami Valley , Whitewater Valley, and the I-71 corridor of Ohio/Indiana:
An arctic front will slip through the region late tomorrow and tomorrow night. This will bring light snow to the region. Generally 1 to 2 inches will be possible by Tuesday morning. Temperatures will quickly drop from near freezing Monday afternoon to the low teens Monday night. Temperatures Tuesday through early Friday will range from just below zero to 15 above. These temperatures combined with winds 10 to 20 mph will make for wind chills as low as -10 at times.
Several rounds of snow showers will be possible to follow this arctic outbreak.
