In the summer of 1980, DC had a record of 59 days with temps of 90F or higher. And guess what?
January of 1981 was over 3F below normal.
Just shows how quick the change can happen. In that summer of 1980 July, August and Sept were above average (August and Sept were well above), October was average and then Nov, Dec and Jan were below average with Jan well below average.
So I know the coldies are just jumping for joy with all this cold, you just never know when it can flip.

This is nuts... I remember last year snow fell in central Wyoming at the "end" of September and everyone was shocked because it was early and leaves were still on the trees... Now here we are beginning of September and snow is flying again.. Might not reach central Wyoming but just amazing! Watches into South Dakota too now.
