If flows are right, you want to hit the Cooper ond/or China Gorge of the Cle Elum. super scenic granite IV-V. might be cranking high though.
Little Wenatchee. Peshastin Creek. Don't forget about Farmlands on the white salmon. If it still has water, hit the WF Hood. Lots of the sky drainage tribs will be going. Top tye, Foss, miller, rapid, etc. Might be worth the drive around Jack's Pass to do a full NF + Main sky combo.
enjoy the trip. it's a great time of year and you'll have tons of options.
