Half way

We are half way through our ground hog project. Here is the summary of the results so far:

Fahrenheit Celsius

Week 1 35.2 1.8

Week 2 31.5 -0.28

Week 3 34.04 1.13

What do you think? Did Alvin predict right about more winter storms or is this really spring on its way?  Can a groundhog really predict the weather?  Is he right or is he wrong?  Scientific or lucky?
