According to meteorologist Mark Torregrossa, the Great Lakes are about 6 degrees colder than last year at this time, and averaging anywhere from 1-3 degrees colder than normal. What does this mean? If the lakes continue to hold colder than normal, this means cold air will have an easier time moving into Michigan and the surrounding states, which in turn could mean the lakes freeze over more quickly as well. With this cold weather pace, residents of northern states could be looking at colder temperatures in November and December. Burrr!
