JibberinoHintertux, Saas Fee, Zermatt, Kitzsteinhorn, Dachstein and Kaunertal are all good candidates. Most snowsure will be the 3 first.
Also, deux alpes should be open by then. their summer setup is pretty good i expect their winter to be even doper.
Not sure there is going to be snow but you could try seiser alm, it's hosting the first official slopestyle event in Italy this year. But, it's also true that last year around november there was still flowers growing on all the dolomites.
R.I.P. JP, Andreas, Sam, Ryan, Erik, Sarah, Shane, Liz, and all of those who died doing what they loved.
