  Cooperstown, Griggs County

  1 injured, $7M damage

  What happened

  The hail began near Jessie, cut a 3 by 12 mile long swath of damage, and ended 3 miles south of Cooperstown. The hail lasted for 15 minutes in Cooperstown, breaking windows, and damaging homes and businesses. One car dealership sustained $400,000 worth of damages. 20,000 acres of crops were destroyed, the equivalent of 20 farms. A 15 year-old girl, driving in the storm, suffered minor cuts due to flying glass. One hailstone recovered near Cooperstown measured 4 by 7 inches.

  Griggs

  $6M damage

  What happened

  An intense low pressure system, with center pressures around 28.8 inches, tracked from Fergus Falls to International Falls, Minnesota. The initial rain was accompanied by lightning and thunder in southern Grand Forks county, and then changed to freezing rain as the temperature dropped. One-half to 2 inches of ice built up on exposed surfaces. Hundreds of power poles and lines snapped due to the weight of the ice, cutting power to many homes and businesses, many of which were beginning to fight the spring flood. The wind reporting systems on the AWOS and ASOS sites across eastern North Dakota froze in place, remaining out for 7 days. The three inches of liquid equivalent from the storm fell on top of a record snowpack.

  Griggs

  $6M damage

  What happened

  With falling temperatures on the back side of the low, the freezing rain turned to ice pellets and then to snow. A strong pressure gradient created winds up to 65 mph, dropping visibilities down to zero. The strong wind, on top of heavy ice accumulations, caused thousands of power poles to snap. This cut power to over 100,000 people in eastern North Dakota and northwest Minnesota and resulted in $30 million in damages just to the power infrastructure. A 2,060 foot television tower collapsed near Galesburg on April 5th. With power cut, many people had to seek shelters with generator power in order to keep warm. Some smaller communities were without power for more than a week. Most television and radio stations were knocked off the air, causing one Fargo radio station to become the only source of storm news for the area. In Grand Forks, 3 inches of ice pellets fell, and as the wind increased, one foot drifts of ice pellets were created. Snowfall totals on the 6th ranged around 7 inches. Interstates 29 and 94 were both closed in North Dakota, along with US Highway 2 from Lakota to Grand Forks. A 33 year-old Lankin man died from exposure, after walking away from his...
