Unseasonably cool air associated with a strong upper level low over the Great Lakes region combined with warm Lake Erie waters to produce persistent, intense lake-enhanced rainfall which trained repeatedly over northern Erie County, Pennsylvania during the early morning hours of the 30th. Over 4 inches of rain fell along the Interstate 90 corridor from near Girard to just south of Erie, with isolated locations approaching 7 inches of rain.
