Spring, Not Spring, Spring, Not Spring

The way the temperature has been changing these days you would think it was on a roller coaster. This weekend it was up in the 70's and tomorrow it is suppose to be 40 degrees. This is March so you never know what the weather is going to do, but this year has been crazier than normal. Is this actually a change in the weather pattern or a weather cycle? I don't know which but, it's crazier than ever.
