Well put ZAZ and I'm glad you lived to tell the tale!
This is a good forum for us to share these kind of experiences. We need to talk about them ourselves to get it off our chests, and perhaps we can learn something from it at the same time?
Particularily judging the weather is something I struggle with everyday at work. Our homebase has no cloudmeter and no accurate measurement of RVR. What is reported as CAVOK can often turn out to be minima plus 100... Very annoying indeed. We have adopted a system in which we always report the various cloudbases etc. More or less systematic use of PIREPS and it helps a lot.
