Severe pulse storms occurred across the area on an afternoon basis from August 7-11. The most impactful afternoon/evening occurred on August 10 when severe pulse storms affected the Springfield metropolitan area. The Route 66 Festival with estimated 60,000 people was in both a Severe Thunderstorm and Flash Flood Warning with eventual cancellation of activities for the night. On August 7-8���A storm complex that developed during the late evening of the 6th and early morning hours of the 7th over Kansas pushed an outflow boundary into southwest Missouri.
Strong to severe storms developed along the boundary intermittently from the late morning of the 7th to the late afternoon of the 8th . The strongest storms impacted areas to the south and east of Springfield, and produced straight line wind damage to trees and roofs. One barn in Oregon County was destroyed due to the strong winds and a boat dock on Table Rock Lake was flipped over. Several roads in Branson flooded as a result of heavy rainfall during the afternoon of the 8th. Two-day rainfall totals averaged between one and one and a half inches along and south of Highway 60. Localized accumulations over two inches occurred near Branson. From August 9-12, a weak front stalled over the region and interacted with a very moist and unstable air mass to produce scattered late afternoon and early evening strong to severe storms across the region each day. Several of the storms produced hail up to the size of golf balls, wind damage to trees, powerlines, boat docks and roofs, and localized flash flooding. The majority of the storms affected the western half of the region on the 9th and 10th , with storm coverage becoming more isolated on the 11th and 12th.
