Abstract
On 23 March 1966, thundersnow was reported over a period of 9 hours (non-consecutive) at Eau Claire, Wisconsin. This event is unique, as it constitutes the longest period of thundersnow (known to these authors) at a single station from a surface observation dataset of 226 stations spanning the years 1961-1990. In this study, the characteristics of a long-lived snowstorm with lightning and thunder are examined. Using model output from a simulation by the Workstation Eta (WS-Eta), we determine that the thermodynamic characteristics of the thundersnow event do not change appreciably with the evolution of the cyclone in this case. For the duration of the event, Eau ...
