EF2 tornado in Newton County, Missouri

The National Weather Service storm survey team determined that an EF-2 tornado touched down 5 miles east northeast of Diamond, Missouri. It remained on the ground for approximately 17 miles, seven of which was in Newton County before it crossed into Lawrence County. The maximum wind speeds were estimated at 120 miles per hour. The tornado damage path had a maximum width of one half mile. There were numerous trees uprooted, three mobile homes suffered considerable damage or were destroyed west of Wentworth. Numerous power poles were blown down along Highway J along a nearly four mile stretch. In Wentworth, numerous tress were uprooted and one outbuilding had its roof removed. The tornado crossed into Lawrence County as an EF-1 just north of Douglas Fir Road along Lawrence County Avenue.

A strong upper level trough across the central plains region and a strong upper level disturbance along with a frontal boundary in the area produced numerous severe storms with a few supercells across southeast Kansas. One cyclic supercell associated with the system produced a very large and deadly EF-5 tornado that hit the city of Joplin and then spawned two separate tornadoes that moved across southwestern Missouri. A separate tornadic supercell produced an EF-3 tornado that moved into McDonald County from Northeastern Oklahoma.

Continuing thunderstorms lasted into May 23 as another line of thunderstorms moved across the region. This line of storms produced reports of large hail, damaging winds and a weak EF-0 tornado in south central Missouri. As the storms moved over the Joplin area, two police officers were struck by lightning while aiding in the post tornado efforts. One of the two officers later died of injuries from the lightning strike.
