Snowfall began in western Ohio at about 10pm and reached central Ohio by midnight on the 4th. It began as flurries and light snow showers but gradually increased in intensity overnight and into the morning of the 5th, becoming heavy at times. By the time that the snowfall ended around 2:30pm in the afternoon, 4-6″ covered most of central Ohio, with the heaviest accumulations right near the I-70 corridor. Another max of snow occurred along a Mansfield to Canton line where a general 4-6″ also occurred.
The night of the 5th-6th brought a cold night for most of Ohio as clear skies after the storm and snow-covered ground sent temperatures far below normal. Most areas saw temperatures in the single digits, and many even fell into the single digits below zero. For Columbus, the low of 9 was the second lowest temperature ever recorded for the 6th of December.
