Fire weather:: planning forecast for Western Washington National Weather Service Seattle WA 313 PM PDT Wednesday Aug 20 2014 current warnings/watches — none.
Discussion — a deepening upper level trough and onshore flow will be the dominant weather features for the bulk of this week. This combination will allow for below average afternoon high temperatures and the slight chance for light precipitation over portions of Western Washington — with the best chances over the mountains. As this upper level trough deepens further on Friday — instability over the Cascades may give rise to the potential for wet thunderstorms. The trough is expected to shift East this weekend allowing for temperatures to rebound to near seasonal normals.
Forecast for 20 foot wind speed (valleys and ridge tops) are 10 minute averages reflecting raws winds.
