In reply to markphilipjackson:
There was a stack of fresh snow down to about 1500 m until last weekend when a strong "libeccio" wind from Africa and torrential rain stripped it back to about 2500 (above which you can still expect plenty of fresh snow). Since then it has been cold at night and normal Autumn cool during the day so there is almost certainly a bit of surface ice up high. Forecast is more snow this coming weekend down to around 2000 m then improving from Monday.
So you need to plan for mixed conditions and you need to be careful not to sleep in some remote bivvy hut (a wonderful thing to do in itself) and wake up to find a metre of fresh snow and a wade out epic.
In these conditions the easy normal routes are typically much more challenging. Via ferratas tend to hold snow because they generally follow ledge systems.
Repeating what I have said in other threads, at this time of year (and in these conditions) I would go walking on the (easy) glaciers of the Adamello/Presanella group (just west of the Brenta Dolomites) because a bit of fresh snow basically makes no difference to your plans. Gorgeous free bivvy huts up there, nice easy peaks to climb and nobody around at this time of year.
The logic is that an easy Dolomite summer scramble becomes rather grim with 20 cm of snow on it, while a glacier plod remains much the same.
Of course you could apply the same logic and go up the normal glacier route on the Marmolada (they might even be skiing already by then).
Have fun
