Long range forecast are always, well almost always, not much good for day to day so I always look for patterns. It is shaping up overall to be dry but the Chehalis has the Olympic side of the basin and upper basin and rain events can be totally different. Bounce the Olympic side early flows right up down color couple three days mainstem good to go. With the time drag for upper basin water to make tidewater if both go out your 7 to 10 days to clear. Inch over a couple days minimal effect but inch in 6 to 8 hours different ball game. Cooler temps in Oct. is a good thing to be sure. Everything I can find says Nov. butt ugly and I think I am being generous on that one.

It would appear that the pattern changes a bit the last of Sept with an event but a bit out for the crystal ball thing.
