IRON MOUNTAIN - It's been colder, but not much.
The mid-November 2008 through January 2009 period was the second-coldest on record at Iron Mountain-Kingsford, the National Weather Service said.
The average temperature from Nov. 15 through Jan. 31 was 12.3 degrees, said Kevin Crupi, weather service meteorologist. It was colder only in 1976-77, when the average temperature over the same span was 10.7 degrees.

Last month was also the second-coldest January on record, Crupi noted.
The average temperature at Iron Mountain-Kingsford was 5.3 degrees, which was 7.1 degrees below normal. It tied 1977 as the second-coldest January. The coldest was 1994, when the average temperature was 3 degrees.
"For the second month in a row, sustained Arctic cold held Upper Michigan firmly in its grip, as a persistent upper trough remained in place across eastern Canada and the Great Lakes," Crupi said.

Areas away from Lake Superior tended to be much drier than normal in January, Crupi said.
"Since a northwest flow of Arctic air prevailed, most of the moisture laden storm systems developing in the Plains were forced south of Upper Michigan," he explained.
