September 2, 2010 Wind Damage from Severe Storms
Beginning in the late afternoon hours of Thursday, a batch of showers and thunderstorms developed behind a cold front in Ottawa and Cloud counties. At the time, the storms were not severe, but as they moved east southeast into an area of higher instability, severe thunderstorm warnings were issued. The warnings included Wabaunsee, Morris, Lyon, Shawnee, Osage, Douglas, and Franklin counties where damaging winds in excess of 70 mph and hail to the size of quarters were possible.
Storm reports consisted of quarter-sized hail near the towns of Eskridge, Carbondale, and Scranton in Wabaunsee and Osage Counties respectively. As the storm moved over southern Wabaunsee County at 4:00 PM, a localized microburst with estimated winds in excess of 70 mph caused extensive damage to trees, power lines, and small structures. One report from the town of Chalk in Wabaunsee County had two-foot diameter trees uprooted, bales of hay blown apart, power poles downed, and a dome on top of a silo collapsed.
