- Injuries and deaths are for the tornado’s whole path, which may extend beyond the county. Deaths recorded within Clay County: 0.
- Weak tornadoes were under-recorded before Doppler radar coverage became national in the early 1990s, so earlier decades read low. Ratings use the Fujita scale before February 2007 and the Enhanced Fujita scale after.

- A smoke day is a date on which a smoke plume traced by NOAA Hazard Mapping System analysts from satellite imagery covered this place's point (the county's population centre or the city centre). Counts here are of medium or heavy smoke. Since 2018 analysts have often drawn light smoke as one area over most of the continent, so light-smoke counts are not comparable from year to year. The plumes show smoke anywhere in the air above, not air quality at the ground, and smoke hidden by cloud is missed.

- The Palmer Drought Severity Index is computed by NOAA each month from the county's average temperature and precipitation, relative to the county's own climate. Zero is normal; -3 or lower is severe drought and -4 or lower extreme drought. It describes the long-term balance of moisture, not water supply or crop losses.

- Earthquakes of magnitude 2.5 or more in the USGS Comprehensive Catalog since 1900. Within 50 miles means the epicentre lies within 50 miles of the county boundary (or inside the county).
- Small earthquakes were under-recorded before the modern seismic networks of the 1970s and are still missed in remote areas, so early decades read low. Magnitudes are as the catalogue reports them and mix scales (moment, local and body-wave).

National Weather Service narrative
A wide variety of significant winter weather began impacting portions of south central Nebraska during the day on Friday (12/29) and continued through Saturday night (12/30), before exiting the area on Sunday (12/31). Freezing rain, sleet, and snow began Friday afternoon in portions of Dawson county, with snowfall amounts as high as 9 inches. By Friday night most of the precipitation had turned to sleet and freezing rain, pressing further east to around highway 281. This led to significant ice accumulations which continued through Saturday night. The areas just west of Grand Island and Hastings received significant ice accrual from the storm, with up to an inch of ice reported…
