Linn County

Every recorded tornado

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

Smoke overhead

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.

1. 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).
2. 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).

Costliest events since 1996

1. May 24, 2004Hail$1.5 million
   National Weather Service narrative

   This appears to be the largest hailstone ever measured officially in the state of Missouri. It was 6 inches in diameter and 16 1/2 inches in circumference. Hail did extensive damage to roofs and crops across Linn County, and the property damage total is reflective of all the hail damage reported in the county.

2. Oct 24, 2021Tornado$250,000
   National Weather Service narrative

   This is a continuation of the tornado that came out of Livingston County. The tornado continued across the entirety of Linn County. For the most part the tornado impacted mainly rural areas of the county, but the tornado did brush by the south side of Purdin, Missouri, causing EF-2 damage to residences near Highway 5. The tornado was well reported by chasers as it approached the northeast corner of Linn County. The tornado was reported dissipated as the storm crossed into Macon and Adair Counties. This was corroborated on the survey with the last damage point in the far northeast corner of Linn County.

3. May 24, 2004Tornado$200,000
   National Weather Service narrative

   Brief tornado touchdown noted near Meadville.

4. Jan 30, 2002Winter Storm, Linn$100,000
   National Weather Service narrative

   A long-lived major ice and snow storm blasted much of northwest, northern and central Missouri from late Tuesday, January 29th, until Thursday, January 31st.

At one point 409,504 total customers were without electrical power in the CWA, with some residents without power up to two weeks. For the Kansas City area, the ice storm was ranked as the worst ever. Further north across northern Missouri, heavy snow fell generally along and north of a line, from St. Joseph to Trenton to Kirksville. Snow accumulations ranged from 8 to 14 inches.

5. Feb 28, 2012Thunderstorm Wind$50,000
   National Weather Service narrative

   Thunderstorm straight line wind gusts were estimated from 80 to 100 mph. One residential building, just west of Highway 5, had its roof taken off. The residents were not home at the time. Many large trees were reported down, along with several barb wired fences.

6. Feb 11, 1999Thunderstorm Wind$30,000
7. Jun 22, 2009Thunderstorm Wind$15,000
