Last nights occlusion

An interesting veer of wind at 4,000 feet last night across Scotland as an occlusion and small low pressure circulation, which brought a spell of snow to many parts of central and southern Scotland, exited stage left (or should that be stage right). The occlusion is still clearly visible well off the east coast in the North Sea, in what is a rather spectacular visible satellite image of IONA at 11 UTC this morning. Here are the observations from the SIESAWs on Cairngorm. You can see how yesterday evening’s severe gale force SW’ly backed into the SSE after midnight, before falling light and veering W’ly at 04 UTC. Last night was not a night for any wild camping in Scotland although the sunrise in the Grampians must have been quite spectacular.
