Coldest year so far since 1899
IRON MOUNTAIN – The first seven months of 2014 marked the coolest January through July period at Iron Mountain-Kingsford since 1899, the National Weather Service said.
The average temperature over the seven-month span was 35.7 degrees, which was five degrees below normal, said Kevin Crupi, weather service meteorologist at Marquette. It was one degree colder than the modern record of 36.7 degrees set in 1996.
“Thanks to a fairly persistent northwest flow of Canadian air into the Upper Great Lakes on the western flank of an upper trough in eastern Canada, Iron Mountain experienced very cool weather in July,” Crupi said.
The average temperature last month was 65 degrees, which was three degrees below normal. The highest temperature was 86 degrees on July 21 and 22 and the lowest was 44 degrees on July 4 and 17.
Although temperatures in May and June were slightly above normal at Iron Mountain-Kingsford, they were far below normal the first four months of the year.
July was dry, as well as cool, with only 1.67 inches of rainfall – 1.78 inches below normal. The U.S. Drought Monitor shows abnormally dry conditions in Dickinson County as well as most of Iron and Menominee counties, along with Florence, Forest and Marinette counties in Wisconsin.
Statistics for the Iron Mountain-Kingsford Wastewater Treatment plant cooperative observer site are based on records that began in March 1931. Any data listed from years before 1931 were taken at nearby sites. Normals used are for the period 1981 through 2010.
Iron River was the coldest spot in the Upper Peninsula in July with an average temperature of 59 degrees, Crupi said.
The long-range forecast calls for normal temperature and precipitation trends from September through November.
