Complexes (groups) of thunderstorms have erupted with stunning regularity in the
Plains and Midwest, rotating around blistering heat which sent readings from Texas
north to Kansas into triple digits. These so-called “MCS’s” (Mesoscale Convective
Systems) are among nature’s most prolific rain and lightning producers and often
nocturnal (nighttime) in nature.
