Thanks for that bookworm, interesting reading, however living in Edinburgh I can tell you it did not rain all day on the 18th. Perhaps there were some showers out to the West of the airport which I did not see.
However I'm not going to eat my words. No, there was no rain 13-18Z, no CBs, good vis all day, and the wind was Westerly rather than Southerly. No, rather I am sticking to my observation that the TAF for the 18th was, as is often, a load of keech. Anyway, that's all, I didn't come to argue with anyone.
