Lake effect snow and bitter cold
ABC-57 News: The next round of snow and cold hits Wednesday into Thursday. A long-lasting band of lake effect snow will blanket northern Indiana and southwest Michigan. Bitter cold and dangerous wind chill values impact the entire area.
Update 1/7 11:30AM: Lake effect snow will continue into this afternoon. The snow will begin to die down by this evening. Many areas will see 2-4" by the time the lake effect snow machine shuts off, with others closing in on 8-10" in very isolated areas under the heaviest bands.
Dangerous wind chills will be a concern long after the snow has come to an end. Expect chills to drop as low as -30° tonight into tomorrow morning. At temperatures like that, frostbite can begin to settle in within 20 minutes. - Greg
