As Buck mentioned it's just impossible to know at this stage. You can look at long term forecasts, check out historical data on weather sites but in reality it has no link to what will happen at the exact time you travel this year. As you get nearer to your departure date the forecasts will become more accurate so the best course of action at the moment is to leave your options open and make your final decision before departing. If it were my trip and based on Buck's recommended route, I wouldn't be losing any sleep about major weather disruption at the end of October, but I would be aware it's possible and leave a bit of 'wiggle' room in my timing.
