National Weather Service meteorologists and Lebanon County Emergency Management officials surveyed a long but sporadic area of thunderstorm wind damage north of Lebanon city. The most concentrated area of damage was located around the Freeport Mills Golf Course, where severe winds estimated near 70 mph knocked down and uprooted over 20 trees along a 1 mile path. The severe winds and associated tree damage produced minor structural damage to the golf course club house and blew out two windows. A separate residential home across the street on Freeport Road also sustained minor damage. Some crop damage was visible along Golf Road near the golf course. Despite credible eyewitness reports of rotating wall and funnel clouds from trained spotters, none of the storm damage could definitely be attributed to a tornado. Therefore, the survey confirmed that the damage was caused by a microburst or straight line winds.
