15.1°C diurnal range

I meant to post these graphics of the diurnal range in temperature across IONA between yesterday’s maximum [06-18] and the overnight minimum [18-06]. It was obviously going to be large on a spring morning after such a near perfect night of radiative cooling across Scotland, and Aboyne didn’t disappoint with a range of 15.1°C between yesterday’s maximum of 9.7°C and this mornings minimum of -5.4°C. In contrast the range at St Athan in South Wales was only 1.2°C.
