Additional showers and thunderstorms will affect Spokane and portions of central and eastern Washington Friday.

A slow-moving storm system will slowly drift inland from the Pacific Ocean into weekend, producing showers and thunderstorms across interior Washington and northern Idaho.

While the threat for severe thunderstorms has greatly decreased, rainfall can be heavy at times, creating the risk for flooding across interior Washington. In the higher terrain, there is a continued threat for mudslides.

A couple of stronger thunderstorms can contain gusty winds and hail across eastern Washington and northern Idaho.

The storm system will also bring beneficial rainfall to a broad area.

Around one-third to half of an inch of rain fell in the Spokane area Thursday, with 0.38" measured at the National Weather Service office in Spokane and 0.57" measured at Felts Field.

Heavier rains fell along the eastern slopes of the Cascades. Flooding downpours created mudslides northwest of Yakima, Wash., which caused the closure of Highway 410.

Flash flooding also caused road closures in and around Wenatchee, Wash. and severe thunderstorms produced damaging winds in and around Walla Walla, Wash.

Over the weekend, the storm system will move past the Rockies and dissipate. High pressure will build in from the west. This will allow a warming and sunny trend over the region.
