A very mild February wrapped up a record-warm winter for the U.S., according to experts from NOAA’s National Centers for Environmental Information (NCEI).
The average temperature across the contiguous U.S. last month was 41.1 degrees F, 7.2 degrees F above the 20th-century average and ranking as the third-warmest February in NOAA’s 130-year climate record. Iowa, Minnesota, Missouri and Wisconsin each had their warmest February on record. An additional 20 states saw their top-10 warmest February on record.
Persistent winter warmth resulted in a steady decrease in ice coverage across the Great Lakes, which reached a historic low of 2.7% on February 11 — the lowest amount of ice coverage on record during mid-February.
Meteorological winter was the warmest winter on record for the contiguous U.S., with an average temperature of 37.6 degrees F — 5.4 degrees above average.
