Good question. I’m no weather man…but i think this weekend is looking like a Go.
Bensweather.com currently says: “a cool northerly flow will also draw additional drift smoke into the area from wildfires in Northern California, clearing this weekend as the flow turns more southwesterly” [emph mine].
Note also the live-cam shot of SGW North on same website, looks clear now at mid-day. [So too does fire-alert cam of south slopes shot from Snow Peak 2]. No unhealthy air warnings are currently posted for Forest Falls this weekend–whereas there were on several days in recent high-humidity weeks.
Monitor all the available sources through this evening and unless something changes tonight i’d plan to go for it. Enjoy your hike!
