Feather edge cirrus over France

High Odilo still holds firm just to the west of central Norway (1037 hPa) this morning as a plume of warmer air produces a thick band of cirrus across France and Switzerland, which gets blown into a beautiful feathered edge effect by light southwesterly winds, as it comes westward. Well, that’s what I assume is happening looking at the 300 hPa winds, you’ll notice that the upper air soundings from the UK are conspicuous by their absence again. A small patch of haar blowing up the coast of Caithness evaporates as the morning progresses as do the patches that have been hanging around the Shetlands for the last day or so.
