May 2015 Weather Summary

I'm not going to comment too much on how the weather felt this month. This is because I have been out of state. Instead, I will point to a recent Scott Sistek blog post.

As I have stated several times, warm weather helps scores during cooler months and hurts scores during warmer months. This 5th warmest May turned out to have the 5th worst score when only factoring in the temperature.

It was also a dry month. When precipitation is taking into consideration, this was our second worst May on record.
