 Brief Description: EVENT NARRATIVE: The tornado moved from Marion County, north-northeast of Rea Valley, into Baxter County, just east-southeast of Cotter. A survey by the Red Cross indicated 21 houses were destroyed, 23 suffered major damage, 35 had minor damage, and 147 others were affected. In addition, 9 mobile homes were destroyed, 12 suffered major damage, 10 had minor damage, and 10 others were affected. One fatality occurred in a mobile home park. Most of the residential structures were in the area around Gassville. A number of businesses in Gassville, along U.S. Highway 62/412, were damaged. Numerous trees, power lines, and power poles were blown down. The tornado dissipated before reaching Mountain Home. EPISODE NARRATIVE: Early on the 5th, a strong storm system approached from the Plains. Ahead of the system, breezy southerly winds provided well above normal temperatures and abundant moisture. Warmth and moisture destabilized the atmosphere and fueled developing thunderstorms. A cold front moved across the state causing numerous severe storms and several tornadoes. One of the tornadoes tracked from Yell County to Sharp County, staying on the ground for 121.84 miles. This track length set a record for the longest tornado path ever recorded in Arkansas. The continuous track was confirmed by two National Weather Service meteorologists who flew the track with the Civil Air Patrol. The final track was based on ground surveys, the Civil Air Patrol flight, and an aerial mapping flight performed for the Arkansas Forestry Commission.

 Brief Description: This tornado was spawned from the same cyclic supercell that produced a tornado across Lawrence, Christian, and Greene counties. A large tornado touched down northwest of Fordland and lifted approximately 7 miles north of Diggins in rural central Webster County.

 Brief Description: EVENT NARRATIVE: A National Weather Service storm survey revealed that an EF-2 tornado tracked across rural areas of east central Greene County south of Strafford. Several homes and outbuildings sustained damage prior to the tornado tracking into Webster County. EPISODE NARRATIVE: An unusual mid winter tornado outbreak occurred over southwest and central Missouri. 31 tornadoes struck the region within a 15 hour time frame on 7 January into early morning 8 January. Two tornadoes intensified to EF-3 status while five tornadoes caused EF-2 damage. All other tornadoes during this outbreak were surveyed and given EF-0 and EF-1 status. Multiple training supercells spawned most of these tornadoes that occurred along the Interstate 44 corridor. Toward the end of this episode, a broken squall line spawned numerous EF-0 and EF-1 tornadoes across the southern Missouri Ozarks.

Six injuries and two fatalities occurred in rural areas north of Marshfield. EPISODE NARRATIVE: An unusual mid winter tornado outbreak occurred over southwest and central Missouri. 31 tornadoes struck the region within a 15 hour time frame on 7 January into early morning 8 January. Two tornadoes intensified to EF-3 status while five tornadoes caused EF-2 damage. All other tornadoes during this outbreak were surveyed and given EF-0 and EF-1 status. Multiple training supercells spawned most of these tornadoes that occurred along the Interstate 44 corridor. Toward the end of this episode, a broken squall line spawned numerous EF-0 and EF-1 tornadoes across the southern Missouri Ozarks.
