It’s the first day of meteorological spring but the season changed weeks ago for much of the United States. February brought more severe weather than it did winter storms this year, and there was a notable lack of snow in the Midwest.

Weather records in Chicago go back nearly 150 years. In that time, there hasn’t been a single January-February combo that didn’t have snow on the ground at some point, until this year. In fact, they haven’t had snow on the ground since Christmas.

Lake Shore Drive, so often buried in frozen precipitation, has been smooth-sailing. Boating down the Chicago River in winter never looked so good. Chicago’s average temperature last month was nearly 11 degrees warmer than normal, making it the third-warmest February on record for the Windy City.

Minneapolis also tied the record for least snow in February with just 0.3 inches.

The jet stream over was amped way north into Canada which put pretty much all of the U.S. east of the Rockies in a warm air mass. The pattern was so odd it led to new records from the Upper Midwest to the Southeast to New England. It was the warmest February for Atlanta; Cleveland; Washington, D.C.; Baltimore; Philadelphia and New York City, to name just a few.

If February alone, more than 10,000 daily warm records were broken or tied in the U.S., compared to around 350 cold records. That pretty much sums it up this winter.
