- Injuries and deaths are for the tornado’s whole path, which may extend beyond the county. Deaths recorded within Jefferson 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.

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).

- Landslides mapped in the USGS compilation of landslide inventories across the United States (version 3.0, 2025), rated probable or better. The compilation joins inventories made by federal and state agencies for different purposes and areas, so the number mapped in a county reflects how closely it has been surveyed as much as how often its slopes fail. An area with few records may simply not have been mapped. Deaths are as recorded in the inventories; a slide listed in two inventories is counted once.

- May 7, 2015Flood$5.0 million
National Weather Service narrative
Extremely heavy rainfall of 6 to 10 inches fell across the northern basin of the Little Blue River. This cause the river to swell to record levels around the Fairbury area. The flooding resulted in the mandatory evacuations of areas of the western and southern parts of town, to the west of the Union Pacific Railroad tracks. The flooding of some residents along the river did result in one fatality of an elderly residence in her basement. The river crested at 25.42 feet or 6.92 feet above flood stage.
- May 29, 2008Tornado$1.8 million
National Weather Service narrative
This tornado was a continuation of a long-tracked tornado that started in Jewel county Kansas and tracked into Thayer county Nebraska before crossing into Jefferson county Nebraska. The tornado did EF3 damage in Kansas and EF2 damage in Jefferson county. ||In Jefferson county the tornado started 2 miles west and 1 1/4 mile north of Reynolds, knocking over large tree branches, snapping trees and overturning several center pivot irrigation systems. The storm tracked northeast from there continuing to snap wooden power poles and causing additional tree damage as well as farm outbuilding damage. The tornado crossed the Little Blue River 2 3/4 miles northwest of Fairbury before turning…
- Oct 25, 1997Heavy Snow, Jefferson$1.5 million
National Weather Service narrative
A major early season snowstorm struck the area. A heavy wet snowfall of 6 to 14 inches fell on trees, many of which were still fully or partially leafed, and caused extensive damage and/or total destruction. At least 205,000 residents in the affected area were without power just after the storm, many of the outages lasted for several days. Omaha Public Power District estimated that it was the worst outage in 50 years. Nearly 85% of the trees in the Omaha area and 25% of the trees in the Lincoln area sustained damage or were totally destroyed. Many emergency shelters in and around the Omaha and Lincoln areas were opened for use by those who suffered a hardship from the storm.
- Apr 29, 2010Tornado$650,000
National Weather Service narrative
An Assessment team from the NWS determined that a tornado tracked around 3 miles west through northwest of the Diller area. The damage path was around 300 yards at its widest. Trees and farm outbuildings were damaged along its path and 35 large power poles were snapped. A house in the area also sustained major damage to the roof and windows and the upper floor was partially shifted from the lower floor and a wall was bowed outward and garage destroyed. A center irrigation pivot was damaged at the tornadoes lifting point.
- Jul 18, 2001Thunderstorm Wind$500,000
National Weather Service narrative
A supercell thunderstorm produced a 20 mile long path of damage due to downburst winds across Jefferson county. The winds were estimated at between 80 and 90 mph. The winds toppled trees and damaged roofs and windows most significantly in a 3 block wide swath in southern Fairbury. Power poles were snapped and several sheds and garages were also destroyed in this area. In rural areas there were center pivot irrigation systems and grain bins overturned as well as scattered tree damage.
- May 7, 2015Flash Flood$500,000
National Weather Service narrative
The emergency manager reported that flash flooding continued as heavy rainfall continued during the overnight. The flooding destroyed a bridge along state highway 15 in northern Jefferson County.
- Jun 13, 2001Thunderstorm Wind$500,000
National Weather Service narrative
An area of apparently straight line wind damage was reported from southwest of Fairbury to north of town. Grain bins were destroyed, roofs were damaged, cars thrown, trees were uprooted and power poles were snapped. This was the second slow moving supercell to track across Jefferson county this evening.
- Jun 13, 2001Thunderstorm Wind$400,000
National Weather Service narrative
This slow moving supercell earlier produced a tornado in the adjacent county in northern Kansas. In Nebraska, near Reynolds, most of the damage was apparently caused by straight line winds, possibly from the rear flank downdraft, estimated at close to 100 mph. The strong winds stripped corn nearly to the ground in this area, overturned center pivot irrigation systems and grain bins and did some outbuilding damage. The winds also uprooted trees which blocked Highway 8 in town.
- May 8, 1996Tornado$350,000
National Weather Service narrative
Another tornado formed from the same supercell that produced the Gilead and Gladstone/Alexandria tornadoes. During its 21/2 mile path, the tornado severely damaged two farmsteads and extensive damage to seven other farmsteads. Damage was estimated at $350,000.
- Jun 4, 2008Flash Flood$250,000
National Weather Service narrative
Heavy rain caused flash flooding that washed out several roads and a bridge near Daykin and also produced runoff from farm fields that flooded across Highway 15 north of Fairbury. Rainfall from the thunderstorms was likely 2 to 4 inches from late afternoon of June 4 into the early morning hours of June 5.
