Snowfall Summary and Map [April 16-17] Snowstorm

Satellite Imagery contrasting the fresh snow cover receding clouds.

 

Event Facts:

 

·         Snow Accumulation: A swath of 8 to 16 inches stretched from just west of Hutchinson, MN northeast to northwestern Wisconsin, including most of central Minnesota and portions of northeast Minnesota. 

    The highest total reported was 20.0 inches in North Branch, MN.

 

·         Wind: East to north winds 10 to 20 mph with some gusts as high as 30 mph.

 

·         Impacts: Intense snowfall rates of 1 to 2 inches an hour caused significant travel delays across the region throughout the day and evening on the 16th. Several school districts closed early and remained closed on the 17th. A fatal accident resulted from the slick roads in Wright County.

 

·         Other: The rain/snow line was very well defined and remained nearly stationary throughout the event. This led to incredible snowfall accumulation gradients. The rain/snow line occasionally mixed with sleet and freezing rain with light accumulations.

 

Overview:

 

A nearly stationary intense band of snow set up from southwest through northeast Minnesota and northwest Wisconsin as low pressure tracked just to the south. Temperatures held steady in the upper 20s to lower 30s within the band of snow, however just to the south they reached the 40s and 50s. A sharp rain/snow line also remained nearly stationary, which led to extreme snowfall gradients across the area. For example, snowfall totals across Hennepin County ranged from nearly 13 inches in Rogers, MN to less than a half inch near Minneapolis/St. Paul International Airport.
