  1. Injuries and deaths are for the tornado’s whole path, which may extend beyond the county. Deaths recorded within Christian County: 0.
  2. 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.

Days each year on which a satellite-traced plume of medium or heavy smoke covered the county’s population centre, 2011 to 2025.
  1. 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.

  1. 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.

    National Weather Service narrative

    A severe thunderstorm produced 2.50 to 4.00 of rain within 90 minutes in northwest and central Christian County, including parts of the city of Taylorville. Most rural roads from Taylorville to Edinburg and Kincaid were impassable. Some city streets and basements in homes in northwestern portions of Taylorville were also flooded.

    National Weather Service narrative

    A tornado touched down along IL Route 48 on the southwest edge of Stonington at 5:34 PM CST. At this time, two circulations aloft merged near the west side of Stonington, causing the tornado to take a sharp turn toward the north. Much of the damage in the town was on the northwest side where house roofs were impacted and several garages and sheds were destroyed. The tornado continued tracking to the north and did significant damage to outbuildings at a farm 4 miles north of Stonington. The tornado then curved toward the northeast, damaging several more outbuildings and sheds before it dissipated near Mosquito Creek, about 5.9 miles east-southeast of Mt. Auburn at 5:52 PM CST.

  4. Dec 27, 2015Flood$2.8 million
    National Weather Service narrative

    An extended period of heavy rain during the evening of December 26th in Christian County combined with an already saturated ground to produce flash flooding. Rainfall amounts ranged from 2.50 to 4.50 inches in less than six hours, with the heaviest rain in the southern half of the county. Most rural roads and state highways were flooded and impassable. City streets in Taylorville and Pana were also flooded. The flooding continued through all of December 27th. Additional rainfall of 2.50 to 4.75 from December 28th into the 29th aggravated the flooding situation significantly. Every road in the county was flooded which resulted in a shortage of barricades to close the roads. The…

    A tornado formed in Montgomery County (WFO St. Louis CWA) and crossed into Christian County 4.4 miles southwest of Morrisonville. Just inside the Christian County line the tornado took the roof off of a shed and smashed it into the southwest corner of a house at the second level bedroom. A camper was tipped over on its side and a visible tornado track could be seen in the cornfield surrounding the house. A mile and a half northeast, a 16 foot wide garage door was completely removed and the west wall of the attached garage was removed as well. A carport on a nearby house was destroyed. Further up the road numerous power poles were blown down, a house was blown 3 inches to the west…

  8. Nov 17, 2013Tornado$300,000
    National Weather Service narrative

    A tornado touched down on the north side of Pana at 12:15 PM CST, then tracked northeastward before lifting 3.1 miles NNE of Pana at 12:18 PM CST. Several homes suffered roof damage near the intersection of Almond and Elm streets on the north side of Pana. Trees were blown down, damaging 3 cars. Numerous power lines were knocked down as well. The tornado moved NNE, damaging a house and destroying an outbuilding before dissipating in an open field.

  9. Feb 1, 2011Blizzard, Christian$260,000
    National Weather Service narrative

    Weather observers across Christian County measured 3 to 9 inches of snow, along with 2 to 4 inches of sleet, and around one quarter of an inch of ice. 40 to 50 mph winds accompanied the snow, reducing the visibility to near zero. As a result of the blizzard conditions, travel became nearly impossible across the area. Due to the ice and strong winds, numerous tree branches and power lines were downed, causing power outages across the county.

  10. Dec 1, 2018Tornado$140,000
    National Weather Service narrative

    This tornado touched down in the National Weather Service St. Louis County Warning Area (CWA) just south of the Montgomery/Christian County line near the intersection of East 000 Road and North 400 Road at 4:48 PM CST. It quickly crossed into Christian County, damaging an outbuilding by knocking out a wall and pushing it off it's foundation. It then proceeded to the northeast, doing roof and wall damage to more outbuildings, as well as some tree damage, before dissipating in an open field about 2.9 miles south-southeast of Morrisonville at 4:54 PM CST.
