September 2004: 20"ish storm in September... actually skied powder in Sept! End result... crappy winter, mountain wasn't 100% open until almost February.
October 2007: Zero snow and remained in the 60's until Thanksgiving... Steamboat had to delay opening 10 days, they couldn't even blow a single flake. End result... 3 straight 100"+ months and record biggest snow year, by a lot.
October 2011: Skied over a foot of fresh from the top of the mountain on Oct 5th. End result... one of the worst winters ever.
October 2014: Snowy October and huge November. End result... again, one of the worst winters ever.
Exactly 365 days ago: Cue the CO whining about warm weather (probably myself included), A-basin wasn't even open yet, minimal natural snow on the ground. End result... I was skiing knee deep powder the next week, many CO resorts opened early, and it was a decent winter.
This weather isn't abnormal at all for October in CO, sometimes it's warm and sometimes it's snowy and sometimes it's rainy. October 28th gives absolutely zero indicator of how the winter will be, it doesn't even give you an indicator of how next week will be.
