Is this truly May?

Today we're busy with the early March winds and the raw temperatures of early April. It's hard to believe that it's May 11th. May is supposed to be in the upper 70's to low 80's with night temperatures in the low 50's. I don't know where this weather came from but it's putting me in a very grouchy mood. This is the kind of weather that gives me severe headaches, penetrates my sinuses and makes me sick. This type of weather should have been done a month ago.
