Fire Weather

... The red flag warning will be allowed to expire at 9 PM this evening for the west Cascades and Olympics. The thunderstorm threat in these areas has diminished this evening.

Elevated fire weather conditions will continue across the Cascades into Saturday with chances of thunderstorms possible again along the Cascade crest on Saturday afternoon and evening. Overall chances for convection will decrease through the weekend, however, as an upper level ridge starts to build into the area from the southeast. By Sunday, expect convection to mainly be confined to the Cascade crest and areas east of the crest. Another upper level trough will move into the area next week and could bring some additional elevated fire weather concerns to western Washington at times.
