I can provide real November-April monthly averages now and 2016-17 month by month totals by late May/early June next year.
November-April averages in inches:
Whistler (BC) 416
Park City (UT) 287 Summit House, 350 top of Jupiter
Big Sky (MT) 283
Vail (CO - I70) 359
Telluride (CO - SW) 278
Squaw Valley (CA) base 270 upper 457
Mt Bachelor (OR) 381
Jackson Hole (WY) 367 mid-mountain
Taos (NM) 259
Killington (VT) 241
In terms of those who might want to track in-season, this is not necessarily the right list of resorts. The good news is that all of these but Big Sky and Taos show a running total of season-to-date snowfall on their websites. It is important to realize that mistakes can be made in daily reporting so occasionally the patrol stats collected at the end of the season may not match. Another issue is that the running totals may include October, and if a website doesn't go live on November 1 it may not be possible until the end of the season to take out the October numbers.
Comments on specific areas above:
Park City: Summit House is obviously what's most representative for skiing, but Jupiter is what's posted online during the season. No data from Summit house will be available until May. If you want one Utah area I would recommend using Alta Collins (519 average), for which there is a daily snowfall tracker on Alta's website.
Big Sky: No season-to-date total posted online. You will see no data until May. If you want another Northern Rockies area you can track, Bridger (302) and Sun Valley (191) are options.
Telluride: Season-to-date total comes online late November and likely include October. The area closes early April and does not report April snow. Sadly, early April closings are common in CO - SW, so only Aspen and Wolf Creek provide full April data. The best data in that region comes from the Rocky Mountain Biological Laboratory in Gothic between Crested Butte and Aspen. Monthly and season-to-date totals are available on RMBL's website.
Squaw Valley: A daily snowfall tracker is online for both upper and lower locations. The relationship between the two varies due to rain incidence at the lower site. If you want one number I recommend averaging the upper and lower.
Jackson Hole: Press releases always quote a site at the top of the Bridger gondola. However the online snow report also shows a season-to-date total in smaller print from the long term mid-mountain site.
Taos: Usually no season-to-date total posted online. They did it for a while last year but not for the whole season. Thus you will probably see no data until May.
The calendars tracking daily snowfall on On-The-Snow.com are not always trustworthy. This data is collected on an automated basis and is not curated in any way. Unfortunately the areas which do not post running totals on their own websites tend to be the least reliable on On-The-Snow.com as well.
As most of you know, I think the best season snowfall predictions are long term averages with a mild nudge during strong El Nino or La Nina episodes. Monthly snowfall predictions are next to impossible due to huge volatility.
