[wc] 3 seasons in 5 days?

[Ellen]

This week in Boston the temperatures will be 53 today, 36 tomorrow, 41 
Sat, 49 Sun, 51 Mon.  Today it is too warm for a coat and tomorrow it's 
supposed to snow.  Is 3 seasons in 5 days one of the symptons of global 
warming?  A cold or mild winter is one thing, but an almost 20 degree 
difference in 2 days is a bit much.  Maybe it's time to move to Florida.
