January-February 2016 had one Billion-Dollar Disaster (tornado outbreak in the eastern US that killed 10 people; https://www.ncdc.noaa.gov/billions/events). The tornado outbreak occurred during an unusual time of year, leading also to high daily extreme precipitation counts in the Northeast (33.3%; 6th highest since 1901), while the rest of the country had less than 15% for regional 20-yr event counts, not reaching either the top-10 or bottom-10 rankings since 1901. The national tally of 10.7% is based on 912 reporting stations.

This season has shown no significant national or regional trends through 2015. However, the high number of daily extremes in the NE region in January-February 2016 anchored an upward trend that reached 94% significance for the 1901-2016 period of record.
