      The observed number of very cold nights (minimum
      temperature below 0°F) for 1900–2014, averaged over
      5-year periods; these values are averages from nine long-term
      reporting stations. The number of very cold nights dropped below
      the long-term average between the 1920s and 1960s, followed by
      an above average number of such events until the early 1990s.
      The number of very cold nights has remained below average for
      the past two decades (1990–2014). The dark horizontal
      line is the long-term average (1900–2014) of 1.6 days per
      year. Source: CICS-NC and NOAA NCEI.
