Michigan 2012: 139 New Heat Records In 44 Counties, 18 Rainfall Records In 14 Counties
When it comes to weather, 2012 was one for the record books as at least 160 extreme weather records were set in Michigan, according to the Natural Resources Defense Council.
Last year's statewide weather broke records across the spectrum including: 139 new heat records in 44 counties, 18 rainfall records in 14 counties and three snow records in three counties.
Michigan's weather seems to be paralleling the national trend of record breaking heat, rain and snow. Across the country, the Defense Council an environmental action group tallied 3,527 monthly extreme weather events, raising the bar over the 3,251 set in 2011, which was the most ever set in a single year since monthly weather was recorded in all locations in 1980.
The severe heat is also held responsible for several extreme weather events statewide. Michigan witnessed four large wildfires and four abnormally early tornadoes, including the EF-3 twister that devastated Dexter, which occurred in mid-March. A March 12 tornado near Midland was also the second-earliest tornado in Michigan since the weather service started recording tornadoes in 1950. The earliest recorded was on Feb. 28, 1974.
