Ive been poking about looking at some low level places these past few days, with overnight temps of -7c this past two nights and -4c on Saturday night the more unusual low level venues are worth a look.
I went for a walk up Ben Wyvis today with family and friends. The temp inversion is present but it isn't super strong as it is totally frozen up top. However there is no snow and only patchy old cover on ridges and shaded slopes in the NW. Have a look at the video and photo which shows the hills from the Fannachs to An Teallach.
