I say 4 weeks to snow on Mt. Washington (10/7) What do you all say?

djop,
I think the first snow on Mt. Washington will fall in September, with as much as 18" additional in October.
I believe the mountain has had some snowfall at some time in all the 12 months. September snow is not that unusual.

Colonel, pick a date. Let's make the game up to 2 days before and 1 days after. So 10/7 (my guess above) wins for 10/5 and 10/8. That should help keep it interesting I think.

Mt. Washington has already had snow although reported as "trace"

Looking further, I see 3 days with snow reported in the August summary;

Locally, I'll take 10/26 for Canaan Valley.

I'll take 10/18 for CV
