Hi We are Australian and my husband and I are wanting to drive from West Yellowstone to Cooke City to Red Lodge to Billings on 12th September 2013. I've read a lot about weather conditions on this hwy which seem unpredictable. i'm really hoping for good conditions as want to see this much recommended scenery but wondering where/who would be best to check with for weather prior to leaving as do not want to get caught in a snow storm. We will have a 4 wheel drive but are not used to driving in such conditions and want to be safe. I know there are alternate routes if we are unlucky with weather.
