OSWEGO, NY – January 2011 started off with a “January Thaw” but it didn’t last more than 2 days.
“We started with a 49 degrees and a 52 degrees couple of days and then things turned real cold for just about the rest of the entire month,” according to Bill Gregway, local observer for the National Weather Service.
The average temperature last month was 22.7 degrees. That is 0.9-degree below average.
The highest temperature was 52 degrees on the 2nd and the lowest was -11 on the 24th. That was the coldest it has been since it sank to -14 degrees on Jan. 22, 2005.
Besides the 24th, the only other day where it was zero or below was the 17th when it hit zero.

From the 20th through the 23rd, the area received 24.5 inches of snow and there was about 30 inches of snow on the ground then, he added.

“January wasn’t as windy as some of the other recent months,” Gregway said. “We only had 6 times where the winds got up around 20 mph or higher. Usually there is more wind ion the winter to blow stuff around. It really hasn’t been a factor recently.”
January 29 marked the anniversary of the start of the Blizzard of 1966, Gregway said, adding the storm raged for 5 days.
