Well, of the 4 groundhogs I pay attention to: Punx Phil, Sun Prairie Jimmy (Wisconsin), Chuck of New York City and General Beauregard Lee of Georgia. We have a 50/50 chance of either a long or short winter.
Punx Phil saw his shadow. 6 more weeks of winter
Jimmy saw shadow too. Long winter.
Chuck saw nothing. Early spring.
General Lee saw no shadow also Early spring.
That does absolutely no good in predicting. I guess it would depend then on where you are?
