SNIP: The length of the US winter is shortening, with the first frost of the year arriving more than one later than it did 100 years ago, according to more than a century of measurements from weather stations nationwide.
The average first freeze over the last 10 years, from 2007 to 2016, is a week later than the average from 1971 to 1980.
Overall the United States freeze season of 2016 was more than a month shorter than the freeze season of 1916. It was most extreme in the Pacific Northwest. Oregon’s freeze season was 61 days – two months – shorter than normal.
