We're starting to see forecasts of potential snow showers 7-10 days out. This early in the season and during the day time that's usually just rain and maybe a little sleet with only the occasional snow flake sighting. I'll probably be looking at swapping over to snow tires towards the end of November, but I need to be careful. Normally riding on narrow summer tires can also get you through a bit of wet snow before you have to go to the studs. Now with the ebike I'm riding a wider summer tire (with very little actual tread) so the switch over may need to occur a bit sooner.
The other consideration is that more of our MUPs/shared urban trails are now paved. On crushed rock the adhesion is generally better even with a fair amount of snow and ice (especially with narrower tires). On new pavement even a little snow can make for less traction that will catch you out.
