This winter has been a tale of two Americas: The Midwest is just beginning to thaw out from a battery of epic cold snaps, while Californians might feel that they pretty much skipped winter altogether. In fact, new NOAA data reveal that California's winter (December through February) was the warmest in the 119-year record, 4.4 degrees Fahrenheit above the 20th century average.
The map above ranks every state's winter temperature average relative to its own historical record low (in other words, relative to itself and not to other states). Low numbers indicate that the state was unusually cold; higher numbers mean it was exceptionally warm. As you can see, the Midwest was much colder than average, while the West was hotter than average (despite a season-long kerfluffle about polar vortexes, the East Coast wasn't exceptionally cold, after all).
As we've reported, there's currently a scientific debate over whether climate change in the Arcitc is making the jet stream "drunk," and thereby increasing the likelihood of extreme cold spells; the exact role of climate change in California's record heat is still unclear.
As anyone working in California's farming industry could confirm, the state also had an exceptionally dry winter, the third-lowest precipitation on record. Other interesting facts from the NOAA report:
