Happy Groundhog Day: No Global Warming in February -- At Least in the Central United States

February, the month of the groundhog, is meteorologically misbehaving. 

I thought it was my imagination: Februarys in Kansas are getting colder. This map (click to enlarge) demonstrates that over the central third of the USA, the month of February is cooling rather significantly. 

I do not know why this is the case. 

Regardless, enjoy the day!
