On January 10, a complex frontal moved inland along the Gulf Coast, colliding with a dry line over the southern central states of Oklahoma and Kansas and Missouri, which led to the formation of a capping inversion later that night. On the following morning, the inversion broke loose, and a cluster of thunderstorms formed over the Oklahoma-Missouri-Arkansas area. By the late afternoon the same day, some of these storms had evolved into supercells, and the NWS SPC issued a Moderate Risk for severe weather, including tornadoes, for about 1600 the same day. This proved correct when the cells began producing very heavy rainfall over the Kansas-Missouri, where a few tornadoes, including an EF2, touched down, doing minor damages in Joplin in the process. The other tornadoes mostly hit rural areas, causing minor roof and tree damages in the same regions. In total, 1 person died, and $12 million was done in damages from the event.
