Storm Summary and Snowfall Totals for April 16th

Spring Snowfall
2011 April 16th

A strong low pressure system affected much of the continental United States Thursday through Saturday, April 14th-17th, 2011. As the low tracked east across the southern plains, it triggered numerous tornadoes from Oklahoma to Mississippi and Alabama Thursday and Friday (April 14th-15th), continuing into the Carolinas on Saturday. 

In the Northland, the low pressure system produced a prolonged period of strong east winds. The strongest winds were found in areas along the shores of western Lake Superior. The Duluth-Superior area saw winds strengthen to 30 mph in the early morning hours of Thursday, April 14th. Winds continued to gust around 35 to 45 mph through early Saturday morning. The strongest winds were found Friday evening when weather stations recorded a few gusts in the 50 to 60 mph range.

By Friday afternoon the center of the low pressure had lifted into extreme southern Iowa as a trough of low pressure extended north along the western Minnesota border. This trough became the focus for heavy snow over much of eastern North Dakota where 5 to 11 inches was reported by the NWS office in Grand Forks.
