The first documented American reference to Groundhog Day can be found in a diary entry, dated February 4, 1841, of Morgantown, Pennsylvania, storekeeper James Morris:
Last Tuesday, the 2nd, was Candlemas day, the day on which, according to the Germans, the Groundhog peeps out of his winter quarters and if he sees his shadow he pops back for another six weeks nap, but if the day be cloudy he remains out, as the weather is to be moderate.
In Scotland, the poem:
If Candle-mas Day is bright and clear,
There’ll be two winters in the year.
If Candle mas be fair and bright,
Winter has another flight.
If Candlemas brings clouds and rain,
Winter will not come again.
