You were right about this weekend... ECMWF now shows low clouds all day Sunday and most of Monday before that trough later in the week. Can't remember seeing the ECMWF change so drastically over a couple runs.
It has been a while since I have been to the forum! I hope everyone has been doing well.
Anyway, if anyone is interested, I updated my charts for climate statistics on various US mountains. I was able to add a lot more new data I was able to dig up over the years (but am still trying to dig up more). Unfortunately the site I put the data on has more ads than it used to, but the data is there and hopefully interesting.

It's isn't that big of a page, but as far as I know this is the only place where the climate data for all these mountain summits is gathered in one place.
If I missed any mountain summits where weather and climate data is available, please let me know.
Thanks!
