Summary of 31 March 2014 Blizzard Event

A complex and intense spring storm system tracked across the northern plains on March 31st, 2014.  The storm system was about 6-12 hours slower to arrive than originally anticipated - but managed to pack a powerful punch!  Snow developed across west-central South Dakota during the morning hours on Monday, with a light wintry mix of freezing rain, sleet, and snow occurring across eastern South Dakota.  As winds increased out of the north-northwest, the combination of moderate to heavy snow and wind speeds in excess of 50 mph quickly led to widespread blizzard conditions west of the Missouri River by noon.  The snow and wind gradually spread eastward, resulting in the onset of blizzard conditions from early afternoon to early evening across eastern South Dakota and west-central Minnesota.  Visibility was reduced below one quarter mile in most areas, with complete white-out conditions at times.  Storm total snowfall amounts were significant, ranging from 6 to 10 inches near the North Dakota border, to 1 to 4 inches along and south of Interstate 90.  

In addition to the snow, a few thunderstorms developed over far eastern South Dakota and western Minnesota.  Several reports of dime to nickel sized hail were reported, along with funnel clouds and even a confirmed tornado touchdown!  What was even more amazing - is that this tornado occurred in an area that received blizzard conditions just a few hours later!  For more information on the tornado, please see the description from the NWS office in Minneapolis/Chanhassen, MN (click HERE).  This just exemplifies the intense and energetic nature of this storm system!  

Below is a tabular and graphic display of the storm total snowfall reported across the area, along with a listing of highest wind speeds.  A summary of the specific blizzard reports by county can also be found be clicking HERE
