Can you change a figure in the Monthly observation

Hello

I really like the monthly observation but I noticed a wrong figure from the weather bug yesterday as their updates were showing a high wind sometimes as 18mph and sometimes as 102 mph and it was this 102 that is showing in the monthly figures although it was just a normal slghly breezy day and the average is showing at just 12 mph.
I would like to change this to 18mph can I do this?
regards Paul

There isn’t really an easy way to manually modify this data. Since this is something that could crop up again, I’m thinking it would be best to allow it to be modified from within Weather Watcher Live. I’ll look into that idea and get back to you.
