The persistence of an upper trough over central and eastern North America resulted in a chilly, active weather pattern over the Upper Great Lakes from the middle of January through April. Many locations Across Upper Michigan saw a top 10 wettest and snowiest February through April period, with precipitation and snowfall as much as 200 percent or more of the 30-year normal. Record February through April snow fell on Munising in 2013. The 109.5 inches that accumulated there from 2/1 through 4/30 is over 50 inches above the 30-year average and about 3 inches more than the previous record total that fell during this same period in 2002.
