loganair cancelled their morning flight to Tiree due to the forecast.

Aircraft being taken off the mountain today to be moved to Farnborough.
Unusual Attitude has the basic facts correct. Freezing level in the area was forecast to be +2 at 5000ft. I would not trust that to be accurate but he could have been above cloud. 10 miles west of Dundee he was climbing through 3700 ft and VMC.
