April 2009 is shaping up as the wettest April since 1983, when 6.55 inches fell at BWI. This month, the airport has recorded more than 5.7 inches, almost double the 3-inch average. Only three Aprils since 1940 have seen more than 6 inches of rain (1952, 1973, 1983). In the 69 years of records before that, 11 Aprils got that wet. Why has the frequency of very wet Aprils declined?
