Wave cloud

There was some lovely wave cloud to the south across the western Cairngorms this evening in Easter Ross. The low dew points the I wrote about earlier today from Cairngorm were fully justified because the dew points were just as low in the Aonach Mor observations as you can see from the thermograms below. The inversion must have been at just under 3,000 feet because at the Bealach Na Ba the temperature hovered at around 2 or 3°C all day.
