Lightning and thunder rolled across the South Sound this morning, and forecasters say the storm could last through mid-afternoon.
“This is the summer of thunderstorms,” said Cliff Mass, a meteorologist at the University of Washington. “One of the most prodigious thunderstorm producers I’ve seen in years.”
This much electricity lighting up the skies isn’t normal in Western Washington, but is one of several thunderstorms to hit the area in the last week. It’s also affecting the temperatures.
Although the average day has been in the 70s, Mass said temperatures in July are typically 10 degrees warmer than they have been.
Forecasters said an unusual pattern of low pressure keeps crossing the area, bringing thunderstorms with it.
This storm has dumped roughly ¼ inch of rain in the Seattle area but should dry out about 1 p.m., forecasters said. Eastern Washington will continue to be deluged and the area has been issued a flash flood warning.
Saturday should be sunny, with a high of 72 degrees, but showers could return Sunday, according to the National Weather Service.
