Abstract
A comparison of 30 years of hourly surface weather observations (1960-1991) from first-order stations and 24-hour snowfall data from climate network stations over the upper Midwestern United States reveals an indirect association between the relatively rare occurrence of thundersnow (< 1 event yr-1 in this dataset) and the accumulation of significant 24-hour snowfall (> 15 cm) in 19 of 22 cases identified. Although no direct relationship is found between the location of thundersnow and the deepest 24-hour snow totals, significant snow accumulations frequently occurred in proximity (< 1° latitude) to thundersnow events. the presence of thundersnow tended to indicate a parent extratropical cyclone capable of producing significant snowfall totals; should thundersnow be anticipated, the operational meteorologist can have much greater confidence in forecasting deeper snow totals.
