| Episode Narrative | A significant episode of severe weather, featuring extremely large and destructive hail and a few brief tornadoes, impacted portions of northwest and north central Missouri during the late afternoon and evening hours on June 7th. The setup for the event featured a slow moving warm front that was draped from far northwest Missouri southeastward into central Missouri. This front had been reinforced by a complex of thunderstorms that had impacted northern Missouri during the overnight and early morning hours prior, allowing abundant low level moisture to become pooled along the front. Strong daytime heating along and south of the front sent temperatures into the middle and upper 80s. With strong instability and moisture in place by late afternoon, conditions were ripe for rapid thunderstorm development as an upper level disturbance moving through Kansas provided the lift necessary for thunderstorms. However, it was the strong turning and increase in winds with height (known as wind shear) that set the stage for severe storms, specifically supercells. While these extremely photogenic storms thankfully were not damaging tornado producers, June 7th featured some of the most destructive hail ever observed across northern Missouri, with two separate storms producing softball and grapefruit size hail, leaving widespread destruction to trees, homes, and vehicles. |
