A complex storm system moved from the Lower Mississippi valley to lower Ontario during this time period. Warm and moist air surged northward from the Gulf of Mexico bringing rain and temperatures in the lower 50s. Rainfall on the order of 2 to 4 inches accompanied the storm system. The warmer air and windy conditions rapidly melted a substantial snowpack of 20 to 30 inches in the region. This, coupled with the heavy rainfall, contributed to rapid stream rises resulting in flash flooding, followed by flooding of the main river channels on Christmas Day.
