Gnome Weather Meter

I don't really want to believe it, but they are giving us an 80% chance of having a snow storm today. Yesterday it was in the mid 60s, Monday it is supposed to be in the mid 60s, but today we are supposed to get 4" of snow.  This, my friends, is the type of craziness we always get here...

And now how to tell weather by gnome-o-meter.
