Isolated to scattered showers and thunderstorms are expected Wednesday and Thursday. These storms may produce dangerous cloud-to-ground lightning strikes which could cause new fires. The most likely areas for thunderstorms will be along and east of the Cascades and into northern California, but areas west of the Cascades may also see thunderstorms, especially on Wednesday. If you have outdoor plans, be sure to include a plan for where to go if a storm develops nearby. Avoid exposed areas like mountain summits, lakes or large fields during storms. Remember, when thunder roars, go indoors! Be sure to wait 30 minutes after the last rumble of thunder before resuming outdoor activities.
