My Friend Ms. C. is going out over the Bogong High Plains this weekend with her hiking chum :-0.
I told her to keep each hut on her route in mind as a refuge from driving winds, rain and snow and do not take short cuts from the pole lines in poor visibility.
The OP would be wise to avoid the Razorback over the coming Friday to Tuesday period. The Summit of Mt. FT would be sketchy in these conditions and the views would be minimal. The Diamantina spur in bad weather is not a place I would like to be.
As LOPS has commented The Bungalow Spur is a safe route up to Fed. Hut in foul weather but proceeding past it has been nearly impossible in some white season trips I have done. Even in Autumn storms the poor visibility and wind chill can be nasty.
I have done it in white season in foul weather a number of times :-0. Even then it required some inner resolve to push onto Fed. hut and get out of the elements and warm the eff up, what with deep snow, driving winds , icy temperatures and all !.Even when it is just raining cats and dogs and miserable ,The Bungalow Spur track is still sheltered but stopping just to eat is not always an option in such bleak weather.
Overall staying in the tree line is wise when the weather turns feral.
If the OP has experience of knowing the early signs of Hypothermia then that is good.
Pole 333 on the Bogong High Plains could be a good place to re enact the last hours of Scott of the Antarctic!.

Mt . Stirling offers good easy to navigate walking or XC skiing in season , many warm and dry huts and a more sheltered mountain experience.
