A low pressure system developing over the central Plains deepened rapidly as it moved across eastern Upper Michigan on the evening of the 13th.  As a result of this strong storm, intense convective snow and blizzard conditions enveloped much of west and north central Upper Michigan on the 13th and 14th.  Higher terrain locations in Gogebic, Ontonagon, Houghton, Keweenaw, Baraga and Marquette counties generally received one to two feet of snow in a 24-hour period.   The greatest storm total accumulations included 33 inches in Rockland, 32 inches in Painesdale and 21 inches at the National Weather Service in Marquette.  Embedded thunderstorms associated with the storm initially resulted in snowfall rates of one to two inches per hour at some locations on the 13th.  Heavy sleet accumulations also occurred at Iron Mountain (one half-inch) and Two Heart in Luce County (one inch). The heavy wintry mix and blizzard conditions caused some road closures, numerous motor vehicle accidents and closed schools area wide, including Northern Michigan University in Marquette and Finlandia College in Houghton.  Blizzard conditions resulted in plows being pulled off Highway  41 from Calumet to Mohawk during the evening of the 13th and early morning of the 14th.  Power outages also occurred from strong winds downing trees on power lines.  The county sheriff reported that the storm cancelled all activities across Ontonagon County.
