In reply to Paul Crusher R:
Yes lots of rock routes in the sella area are roadside and can be done like this as they are only a couple of hundred meters long.
I think the forecast isn't looking too bad at all on the Dolomites site for the forecast period, maybe a bit better than average. It is after all the mountains and some chance of afternoon thunder storms is quite typical in the Alps you just need to plan around it.
