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 nine long-term reporting stations. Since 1990, Oklahoma has consistently experienced a below average number of very cold nights, indicative of winter warming in the region. The dark horizontal line on each graph is the long-term average of 1.1 days per year. Source: CICS-NC and NOAA NCEI.
