OSWEGO, NY – December 2010 goes into the record books colder and wetter than normal. Snowfall also wound up higher than average; the first time this winter season
The average temperature last month was 27.1 degrees. That’s 2.6 degrees below average, according to Bill Gregway, local observer for the National Weather Service.
“That wasn’t really any big deal,” he said. “Going back 43 years to 1968, it’s only the 12th coldest December
The highest temperature was 58 degrees on the 1st and the lowest was 10 degrees on the 19th.
There were no records set during December, Gregway added.
“We had one day in the 50s (58) and 3 in the 40s,” he said. “There were 14 days, all in a row, where the high was below freezing (from the 14th through 27th).”
There were 10 times the low dipped into the teens, he said. We didn’t have any single-digit readings and no below zero readings, he added.
Total precipitation for December 2010 came in at 4.92 inches. That’s 1.12 inches higher than normal.
For the year, precipitation wound up at 48.35 inches, which is 5.42 inches above average.
December had measurable precipitation on 17 days with stretches of 6 days and 5 days in a row.
There were 7 days (2 consecutive) where only a trace was recorded.
And, 7 days (2 consecutive) saw no precipitation.
Snowfall for December was 36.5 inches. That is 3 inches higher than average. And, it jumped the snowfall for the winter of 2010-11 all the way up to 37.2 inches. However, that’s 5.8 inches below where we should be at this point in the winter, Gregway noted.
The area only received 10 percent of the possible amount of sunshine last month. That’s 9 percentages below average.
“The only reason we made it up to 10 was the last two days of the month when we got a lot of sunshine,” Gregway pointed out. “Other than that, our percent would have been abysmal.”
The number of cloudy days, 28, was 3 above normal.
The number of partly cloudy days, 3, was 2 below average.
