Here is a list of the monthly snowfall totals and how it ranks as the 
snowiest April on record. Most locations across north-central and
northeast Wisconsin have smashed the previous snowiest April on record. 
An amazing 45.3 inches of snow has fallen at Tigerton in Shawano County
while 44.0 inches has fallen at Sturgeon Bay.  These totals are not a
state record for the month of April. In 2013, an observer near Bayfield
recorded 47.4 inches of snow for the month while 47.0 inches was recorded 
at the Brule Ranger Station.

Some locations on this list do not have a historical record or have a
very short period of record. For these sites, NA was used for the old
record. The snowfall amounts below are preliminary based on what has
been reported so far. The numbers may still change as additional data 
becomes available.
