Another lovely crystal clear sunny day across Easter Ross and you can just make out Loch Ussie and the Cat’s back from the EODIS visible satellite image. You won’t know what the hell I’m talking about but they are places close to where we now live in Strathpeffer. The Cat’s back is a ridge lying to the southeast of the village and Loch Ussie lies just below that. It’s hard to believe that just two weeks ago people were walking across the frozen ice to the islands in the centre of the loch, and even this weekend there was little ice left in the edges.

I also notice that the SIESAWS on Cairngorm at 1237 M amsl is reporting some remarkably high temperatures today. The 11 UTC temperature for instance was 16.7°C this morning – I’ll leave you to make your mind up about if you think it’s correct or not – I think it possibly could be. It’s certainly perfectly placed at the top of the inversion above this mornings SC layer to have seen these kind of temperatures, and the dewpoint of -14.9°C at the time equates to a relative humidity of just 10%. Here are a few thermographs from other mountain stations for comparison.
