What happened
The episode as NWS IWX wrote it up.
...Synoptic and mesoscale conditions on March 11th...A strong shortwave trough was located over the central plains the evening of the 10th with surface low pressure developing over the lower Mississippi valley. As this system moved northeast on the 11th... it rapidly intensified spreading a developing swath of heavy snow across the midwest with some locations reporting thundersnow in the developing deformation zone north of the amplifing upper trough.As a result... the biggest snowstorm of the season thus ensued across the southeastern third of the county warning area during the late afternoon and evening hours of the 11th. Most locations reported from 6 to 8 inches of snow with many locations reporting snowfall rates of 1-2 inches per hour during the height of the storm with the Fort Wayne airport reporting 4 inches of snow in just 2 hours and a total of 8.8 inches for the event. The heavy, wet nature of the snow caused numerous accidents including some multiple vehicle accidents in Wells and Allen counties.
