The observed number of very cold nights (annual number of days with minimum temperature below 0°F) for 1900–2014, averaged over 5-year periods; these values are averages from 39 long-term reporting stations. The highest number occurred in the late 1910s. Since the 1990s, Nebraska has experienced a below average number of very cold days, indicative of overall winter warming. The dark horizontal line is the long-term average (1900–2014) of nearly 15 days per year. Source: CICS-NC and NOAA NCEI.
