Western Washington was pummeled by a rare summer storm over the weekend. Lightning shattered trees and heavy rain flooded streets across Puget Sound. 

Thousands lost power in Saturday's thunderstorms, but most power was restored by Sunday morning. 

The National Weather Service Seattle reported 2,200 lightning strikes from 6 to 11 p.m. on Saturday. "That works out to an estimated 440 an hour and 7 to 8 a minute," NWS Seattle tweeted

Lightning struck a giant spruce tree along Seattle's Green Lake walking trail. The tree was split down the middle and large sections of the tree came crashing down.

NWS said rain rates approached a half-inch in one hour in parts of Seattle. The storm brought hail and heavy rain into Pierce, King, and Snohomish counties before moving on to Skagit, Island, and Whatcom counties. 

Some flights from Sea-Tac International Airport were diverted to Everett's Paine Field on Saturday. 

The Washington State Fair advised guests to shelter in place as the storm moved through. The concert and rodeo were canceled and the fair closed early due to severe weather conditions. 

Husky Stadium was cleared out during Saturday's game against California. The game didn't finish until early Sunday morning after an extreme weather delay. California kicked a game-winning field goal with 8 seconds to spare for a 20-19 victory over UW. 

Sunday brought much calmer weather to the region with a partly sunny day in Seattle and temperatures reaching into the lower 70s. 

Temperatures through Tuesday will only reach into upper 60s. Cooler air sets the stage for more rain on Monday. Tuesday will bring scattered rain showers, along with a few sunbreaks.
