So just how cold did it get overnight?
Officially, at the National Weather Service office in Cheektowaga, the temperature went down to 0 degrees.
Add the wind chill factor, and it feels like 22 degrees below zero.
But that was downright balmy, compared to some of the unofficial readings in the Southern Tier, especially in Chautauqua County. Spotters reported temperatures – not wind chills – of 9 degrees below zero in Jamestown, 14 below in Sherman and 20 below in Ellington.
And unofficial wind chills included 24 below in Niagara Falls, 25 below in Jamestown and 26 below in Wellsville, in Allegany County, the National Weather Service reported.
“It’s one of the coldest air masses of the season,” meteorologist David Thomas said. “That, in addition to the winds, brought some very low wind-chill temperatures.”
That cold air mass will continue to grip the region today and tonight, although a bit of relief is in sight.
The National Weather Service has kept the wind-chill warning in effect until 10 a.m. Wednesday for basically the southern half of Western New York. In northern Erie, Niagara, Orleans and Genesee counties, the warning is downgraded to a wind-chill advisory from 11 a.m. today to 10 a.m. Wednesday.
The wind chills are expected to reach 15 to 20 degrees below zero in the northern half of Western New York, while again approaching 25 degrees below in the southern half.
The National Weather Service forecast calls for a high of 10 degrees Wednesday and then into the 20s for Thursday and Friday, while the overnight lows should reach about 6 degrees Wednesday and 22 degrees Thursday.
