Arctic Front to Bring Wintry Conditions and Bitter Cold

A strong arctic front will bring heavy snow and blowing snow and high winds across the North Plains. As the front moves south, bitter cold will spread across much of the western 2/3rds of the U.S. Heavy lake effect snow will continue downwind of the Great Lakes, and heavy snow and areas with a wintry mix can be expected in southwest Alaska.

Overview

Multiple tornadoes tracked along a warm front in southern Minnesota during the late afternoon and early evening of March 29, 1998. With a total of 14 tornadoes, it was the largest March occurrence of tornadoes in Minnesota. In fact, prior to 1998, there were only 7 tornadoes known to have hit Minnesota in March.  There was extreme and widespread damage to trees, homes, schools, and businesses.  Massive hail accompanied the storm, with golf ball to baseball size hail common.  The largest hail stone fell in Courtland and was 4.5 inches in diameter.  The tornadoes tracked along a warm front draped across southern Minnesota. Sadly, two people were killed by the tornadoes: an 85 year old man near Lake Hanska, Louis Mosenden, and a 6 year old boy, Dustin Schneider, near St. Peter.
