Wider weather episode

An increasingly active mid-month pattern over central Indiana began early on the 11th amid enhanced lift from an approaching 140 KT jet streak. Lingering moisture from a preceding system, trapped in a stratus deck beneath a boundary layer inversion, with temperatures between -10 and -2 degrees Celsius, produced mainly freezing drizzle for several hours around the morning rush hour. Impacts from the resultant very thin glaze of ice were greatest around the Indianapolis Metro, with several accidents and one fatality.

A more organized clipper system then slowly tracked from the central Plains across Missouri on the 11th, with overrunning moisture falling as snow through the evening and overnight into the 12th. Widespread light snowfall totals over most of central Indiana trended up to mainly 3.0 to 5.5 inches of snowfall along and southwest of a Terre Haute to Brownstown line, which followed two nocturnal bursts of moderate to heavy snow rates.
