Yup, it's official: February was the warmest New York February since people started keeping track back in 1870. At a balmy average of 40.9 degrees, this February ties the 1984 record and caps off a remarkably warm three months, the "second warmest climatological winter on record, trailing only 2001-02," according to Gothamist. By contrast, the coldest February occurred in 1934, when temperatures averaged only 19.9 degrees, a staggering 21 degree difference.
Global warming? Sure. But something else too. From CBS:
According to Arthur DeGaetano at the Northeast Regional Climate Center, the primary cause of this past month’s cozy temperatures is due to a phenomenon called Positive Arctic Oscillation, in which low air pressure in the Arctic region creates a jet stream that blocks cold air from leaving.
“The jet stream acts like a fence or wall that confines the air … and doesn’t allow the cold to come down over most of the [United States],” he told CBSDC.
How's the beginning of March shaping up? Expect showers and a thunderstorm Friday night with a warm, wet Saturday in the 50s, clearing up for a slightly colder Sunday.
