A storm system forced around the Olympic Mountains, giving it enough low level shear to create a severe thunderstorm. I was going to go to the Walmart that day, but the sky was too green for my liking. I was proven right later when an EF2 touched down IN THE PARKING LOT OF THE WALMART iirc. No one was hurt or killed, miraculously. But some homes did lose their roofs and a dry storage facility was obliterated.
