This represents a new absolute high for this day. The previous record was 48°F set in 2002. On the following day a maximum temperature of 46°F was observed, surpassing the old record of 45°F by 1°F set in 2008. The low temperature of the month of -31°F occurred on the last day of December. However, the previous day recorded a low of -29°F, which represents a new record minimum for this day, as the previous record was -25°F set in 1997. In general, the first 2/3 of the month was seasonally somewhat too warm. Thereafter, the temperatures dropped steadily, and by the end of the month far below normal temperatures were observed. The precipitation total was measured at 1.64", above the long term mean of 1.23". Especially remarkable was the record snowfall event on the 11th December with 10", setting a new record for this day. The old record, set in 1963, was only 3", hence it was really an extraordinary event, shattering the old record by more than a factor of 3. Average wind speed was 8.8 mph and the highest gust was recorded at 61 mph on the 10th, blowing from a southeasterly direction.
