Northwest Fire Weather Summary
Warm and dry weather continues today and tomorrow with an upper level high pressure ridge still along the coast. Dry easterly winds are expected over and west of the Cascades again today and tomorrow due to persistence of a thermal trough at the surface. The blocking ridge should give way going into the weekend as a closed low currently well off the California coast approaches with cooler temperatures, breezy winds, and some precipitation. Weather models are still divergent on details for the weekend, so check the latest National Weather Service fire weather planning forecast for the latest projection for your area.

Northwest Fire Potential Summary
Fire danger will continue to rise through Friday with the warmer and drier weather. Western Oregon (PSAs NW04, NW03, and NW07) will see the most increase in significant fire risk due to the combination of drier fuels and gusty east winds. Initiation of new significant fires is not likely, but flare-ups of ongoing incidents are possible due to the elevated burning conditions. Fire danger will begin to moderate this weekend as cooler, moister weather returns.
