Olga successfully merged into a cold front associated with a
stronger, deepening surface low in western Illinois with a central
pressure of 993 millibars, or 29.32 inches of mercury. Ahead of
the cold front and very near the center of Olga's remnants were
shallow but strong thunderstorms capable of heavy rainfall
extending from eastern Kentucky to the Florida Panhandle. A broad
precipitation shield extended from western Illinois across
southern Wisconsin, central Michigan, and into central
Pennsylvania associated more with the tropical moisture
overrunning a frontal boundary fraped across the Lower Great
Lakes. Below are preliminary rainfall observations associated with
Olga and the developing frontal low.
