An area of low pressure passed to the north of Lake Erie during the morning hours of November 12th.  A cold front trailing the low swept east across northwestern Pennsylvania by midday.  Behind the front, cold northwest winds blowing across Lake Erie caused lake effect snow showers to develop around midday on the 20th.  This activity intensified during the evening of the 20th and early morning hours of the 21st.  After a brief lull, another band of locally heavy snow affected southeastern Erie County during the early morning hours of the 22nd.  The snow shower activity tapered off late in the morning on the 22nd after dropping significant accumulations on portions of northwestern Pennsylvania.  Storm totals of over 20 inches of snow were reported at a few locations.  By the conclusion of this event, seasonal snowfall totals at few locations in inland Erie County were already in excess of 50 inches.  Gusty north to northwest winds accompanied the snow showers and caused considerable blowing and drifting.  Travel was severely hampered and many accidents reported during this event.
