Where did this weather come from?

We have had the most incredible weather lately. It has reached the upper 80's and lower 90's depending on which thermometer you are looking at for the past two days. This is unheard of in our area. I have been stuck in my office both days, but I hear it has been such a joy to be out and about in.

I did manage to stay out in it a bit after we got home from dance. Sugar can even be talked into coming inside. She even ate her dinner out there. It is making us yearn for summer days and nights. Can't wait.
