The first documented reference to Groundhog Day in America can be found in a
diary entry, dated February 4, 1841, of Morgantown, Pennsylvania, storekeeper
James Morris.

According to folklore, if it is cloudy when a groundhog emerges from its burrow
on this day, then spring will come early; if it is sunny, the groundhog will then 
see its shadow and retreat back into its burrow, and winter weather will continue
for six more weeks.
