What is up with this weather

Yesterday, cold and windy. Today 60 degrees. What in the world is going on? Every day is like living in a different part of the country. One day is likel living in the northeast the next like living in Florieda. Everyone I know is sick. EIther with siinus or headaches, it is just not right. And the dogs, well they don't even know what to do. I guess no snow this year, until the spring of course.
