May 2013 and The Law of Averages

Look at how much the country has changed in less than 2 weeks! We had snow for the first time on record in May less than two weeks ago, and those same places were in the 90s today! Look at the highs today compared to the snow cover from 12 days ago:

May started out extremely cool, but we may make up for it over the next 2 weeks. Here is a graph showing the highs we saw compared to the average highs:

As of right now, the average temperature for May 2013 is 60.8 degrees. The coolest May on record was in 1976 with an average temperature of 61.4 degrees. As I look at the long range forecast, we may see temperatures above average for the rest of the month, which will raise the average, significantly. I still think this May will be in the Top 10 coolest. I'll keep you posted!

Enjoy the warm weather!
