The coldest temperatures in two years have hit south central Kentucky, Indiana and parts of Tennessee and forecasters say they could stay for a couple of days.
Temperatures early Tuesday morning were in the low teens and a wind chill factor made them feel like low single digits.
Meteorologist Ted Funk with the National Weather Service says the area hasn't seen temperatures this low since February 10, 2011. There's also a chance of what Funk calls "wintry precipitation" later this week with a mixture of rain and snow.
