Below the upper trough you see in this video from 11:15 today, Sept. 20 is the cold front that is creating strong SW wind just aloft and at Sherman Island. Tomorrow will see showers in the North Bay as this feature grazes California on its way to the Pacific Northwest.

In Southern California this upper trough will bring a cool down, a deeper marine layer and weaker coast winds today.

While the Gorge sees gusty winds and showers. By Mike Godsey
