Hi Sonya,
When I did it the first time, it rained (lightly) from early evening through the night and drizzle stopped about the time we started walking in from the queens bothy. Prob took us about 2hrs to get to the base of the route and we found it pretty much dry. A wee bit damp in the back of the first couple of pitches but that was the worst of it.
It was fairly warm with a decent breeze which seemed to be enough to dry it out.
Based on that I'd say if Sunday morning looks fine it's worth a look.
Cheers,
Stu
