The National Weather Service is predicting some of the coldest temperatures of the season this week as a strong aortic air mass settles in on the area. High temperatures are expected to only be around 18 above for the next three days with overnight lows down into the single digits. Wind chills will feel like well below zero. There could be some significant snow too with an approaching storm front that is expected to enter into the area Wednesday. Current models indicate more snow will likely fall south of I-69 than north.
