Thunderstorms Possible In Seattle Area: Weather Service

SEATTLE, WA — One of the rarest types of Pacific Northwest weather might happen this afternoon. Thunderstorms may accompany a band of rain storms expected to strike starting around 3 p.m.

The National Weather Service says the thunderstorms are possible in the Cascades, but also the Puget Sound lowlands. Even if we don't see thunder and lightning, there's still a 60 percent chance of rain.

Why is there a chance of thunderstorms? According to forecasts, there's a low pressure system hanging off the Pacific Coast, and that will draw wind upward and create precipitation. Meanwhile, another system is clearing in the skies over the Cascades.

According to the Seattle Weather Blog, storms will be able to form over the Cascades, and then push back into the lowlands heading east to west.

Remember: When thunder roars, head indoors.
