Global Warming?

Sorry I haven't posted in awhile.  I was enjoying the global warming that we were experiencing here in Chicago.  One day it was 61F this week (Tuesday, to be exact).  Then we moved to some really nice pouring rain (Wednesday).  Then, after the flooding we got some snow (that, again, was on Wednesday).  Finally!  Snow!    It's a balmy 16F outside today.  This was the weather the last three days.   I hope we get some more snow.
