A warm front associated with an area of developing low pressure over northern Illinois moved across northern Ohio and northwestern Pennsylvania late on October 1st through the morning hours of the 2nd.  This allowed strong southerly flow to bring abnormally warm and moist air into the area. Temperatures in the upper 70s to low 80s created moderate instability ahead of the front during the afternoon. Strong low-level wind shear was in place so the environment was primed for severe weather with tornadoes possible. The low pressure lifted northeast to southern Ontario by noon on the 2nd with the associated cold front moving eastward across Ohio. The main emphasis for the tornadic development was an outflow boundary from morning convection over the lake. This boundary (maybe the warm front) was oriented west to east across Ashtabula and Crawford counties. The first storms along this boundary initiated between 1:00 and 2:00 PM in Ashtabula and southern Erie County.  These thunderstorms eventually produced three tornadoes in Crawford County.  The strongest of the three struck a nursing home near Conneautville causing significant damage.  The other two tornadoes struck rural areas and resulted in mainly tree damage.
