A Mesoscale Convective System (MCS) left the Chicago area to cause problems in northern Indiana and Michigan. A Tornado Watch in Detroit was in effect starting at 1:30 p.m. Sunday.
An MCS is a complex of thunderstorms that organizes into a larger scale than each individual thunderstorm. Three thunderstorms passed through Arlington Heights as part of the complex. The storms passed over Lake Michigan, northern Indiana and on to southern Michigan. Two major thunderstorms cells were part of the MCS as of 6:30 p.m. EDT. The MCS almost acts as an overland hurricane with some backward spin of the entire complex. A warm front is heading north. Both Chicago and Detroit area expected to be affected by much warmer weather Monday and Tuesday. Chicago’s high is forecast at 91°F Memorial Day and 87°F Tuesday. Detroit’s high is forecast at 88°F Memorial Day and 90°F on Tuesday.
