Two supercells traversed the St. Louis metro area on Monday night. This first elevated one at Pontoon Beach, IL crossed the northern side of the metro area, producing frequent intense lightning:

A second supercell crossed the southern parts of the metro, producing a tornado near House Springs, MO. I intercepted it near Freeburg, IL before it dissipated. At the time of this image, the storm displayed a pronounced hook/inflow notch on radar:
