Xander here with the annual CFT weather report.
Days will be mostly clear and temperatures will be mild but dry; nights will be chilly but warmer than last year. Pack your lightweight sweaters and bring sunscreen.
All of Oregon is suffering from extremely dry conditions, coupled with high temperatures a Red Flag Warning is in effect. All campfires are restricted to fully enclosed metal fire rings (see related postings). Air quality due to forest fires in southern and northern Oregon can shift drastically. If you have repertory sensitivities pack at least three N95 or N101 particulate masks for good measure.
See you at camp!
