| Episode Narrative | Numerous severe thunderstorms formed ahead of an approaching cold front during the late afternoon and evening of Friday December 10th, 2021. Large hail, damaging winds and five tornadoes occurred across central and eastern Missouri as well as south central Illinois. Unfortunately two of the tornadoes were very strong (rated EF-3 on the Enhanced Fujita Scale) and responsible for 7 fatalities (one near Defiance, Missouri and six at an Amazon Facility near Edwardsville, Illinois). The Defiance, MO tornado tracked within one mile of the NWS St. Louis office in the Missouri Research Park near Weldon Spring, MO leading to the staff sheltering while NWS Kansas City provided service backup. This is only the third time in the office's existence that the staff had to shelter. The damage from the Defiance, MO EF3 tornado was estimated at $684,186 and is unknown for the remaining tracks at this time but early estimates are well into the millions due to the damage sustained at the Amazon facility near Edwardsville, IL. |
| Event Narrative | Once back in St. Louis County, there was additional tree damage and other minor damage noted. The tornado lifted at 8:01 PM before entering the Hollywood Casino Amphitheatre Complex. Overall, the entire tornado (St. Charles/St. Louis counties) was rated EF3 with a path length of 27.30 miles and a max path width of 150 yards. There was one death and two injuries with this tornado. Dollar amount damage is estimated around $3.4 million in St. Charles County. |
