Straight Line Thunderstorm Winds Cause Minor Damage in Montcalm County

Thunderstorms swept across much of southwest lower Michigan late Sunday night and early Monday morning ahead of our first fall airmass of the season. Most locations saw wind gusts of 25 to 40 mph along with heavy downpours and occasional thunder and lightning but a few residents in Montcalm county saw wind gusts to 65 mph with snapped trees and minor roof damage.  The area hardest hit was Sidney Township just northeast of Greenville in Montcalm County.  The NWS sent a damage survey team to the area Monday afternoon to survey the damage and determine whether the damage might have been caused by a small tornado. However, the damage pattern and WSR-88D Doppler Radar signatures show that it was most likely the result of straight line winds associated with a bowing thunderstorm segment.
