Episode Narrative A deep closed upper level low pressure system dropped south to just off the coast of Oregon. This placed the Inland Northwest under a moist and unstable southerly flow pattern. Some energy rotating around the low pressure system during the evening hours sparked off a line of convection that tracked north-northwestward across the Okanogan Valley. Strong outflow winds were reported across this area as the line of thunderstorms moved through.
Event Narrative Strong winds associated with outflow from a cluster of thunderstorms was thought to be responsible for damaging a roof on a resident house. The roof was picked up on the east side of the house and completely flipped over to the west side of the property, damaging two cars parked next to the home. The roof was actually a second roof on top of an old one. Showers the following week resulted in damage to the ceiling, drywall, and the carpet.
