Meteorological Schizophrenia

Is is spring? Or is it still winter? Yesterday I sat in my humble little cube, watching snow drift up on the skateboard ramps. Today it is warm and the sky is a beautiful blue. There is very little sign of the blizzard that befell us yesterday. What gives? How are you supposed to dress for the weather if it can go from balmy to blizzard in less than 2 hours?
