The thunderstorm threat will expand west and northward Wednesday morning through Wednesday evening as available moisture increases. Thunderstorms along and west of the Cascades are likely to produce wetting rainfall at some locations, but also lightning outside of the rain cores in others.

The trough will push to the east of the area Friday with hot, dry weather expected again this weekend. A period of gusty offshore northeast winds may occur Friday into Saturday with moderate to poor overnight humidity recoveries.
Isolated dry thunderstorms are expected to result in new fire starts Tuesday night into Wednesday morning. Wednesday afternoon and evening wetter, scattered thunderstorms are expected to result in additional fire starts. Initial attack resources could be overwhelmed and holdover fires are possible.
