Wider weather episode

Clusters of thunderstorms developed during the late afternoon hours. Some of the largest clusters were associated with sporadic gusty winds in the 40 to 60 mph range. By early evening, a few tornadic circulations were observed as storms intensified. A significant tornado occurred in southeast Missouri. In fact, this was the strongest tornado in the month of July since 1971 in southeast Missouri. The storms occurred ahead of a mid-level shortwave trough moving southeast into the Missouri Valley, with an associated cold front extending from southwest Kansas into northern and central Missouri. During the late afternoon and evening, steep mid-level lapse rates and ample westerly wind shear resulted in organized severe thunderstorms with damaging winds and an isolated tornado.
