strawberry falls and forming temps

[KingsMM]

I'm hopping to climb strawberry falls near Strawberry mtn in Oregon this weekend. Do you think it would be formed? I did the math for the average mean temp for the last 13 days and it is 27.5 deg F. The average mean temp since Oct. 1st is just below freezing (31.5 deg F). I used weather underground's stats for 3,500ft at Prairie City and then added 3.5deg F per 1000ft. Strawberry falls is at 6,800ft. What do you think? I'm just hoping for any little bit of climbable ice nothing grand.

Thanks,

Kip
