In my experience with snow chasing, Route 28 is relatively taken care of but, and this may be a matter of common sense, if it is snowing at say an inch or two an hour, it doesn't matter how well they are taking care of it, driving will be between difficult and dangerous.
A few times I storm chased into snow last year on 28 and I made it safely but in very dark parts of 28 with white out I literally had to drive slightly left into the rumble strip at times in low traffic and dark areas to be able to confirm location on the road.
