Given the way things sit, no one is going to give best case, they will give worst case to avoid people coming back to them throwing their words at them, or bugging endlessly - which will likley happen regardless.
The trend in the forecast in some areas look promising for things to improve, I am sure trails are cleared/brushed at this point, there has been no major storms causing trees down (knock on wood), so add some cold, some snow, some packing/grooming, signatures all good and voila, maybe some yellow trails.....
