With high pressure in charge at this time of the year there is a chance that somewhere like Aboyne could get a diurnal range (night min and day max) of greater than 20°C.

Last night Aboyne dipped to -4.3 and had a max of 15.4°C (I think). Could tonight and tomorrow go one better and breach the 20 degree range?

Have you had an impressive diurnal range recently? If so please share it here.

I suspect tonight and tomorrow might be the best time for a few days at least in terms of large diurnal range.

Well predicted Michael! Aboyne had a min of -6.1 last night (from the synoptic observation at 0600 GMT- the hourly temperature was -5.7 at 0700 GMT so the climatological 09-09 GMT minimum might be a little lower). The temperature at 1300 GMT is 14.5 so there is already a diurnal range of 20.6 degC for the day, and probably a bit more.

There is a long way to go to beat the UK record which is 29.3 degC at Altnaharra in late December 1995. In this case cold air was swept away by increasing wind so it was a change of airmass with the temperature rising from -27.2 early in the night to +2.1 by 0900 GMT the next morning. The highest diurnal range due purely to solar radiation was 29.0 degC at Tummel Bridge in May 1978, from a min of -7.0C to a max of 22.0C that same afternoon. That particular spell was characterised by glorious clear blue skies and very low humidity.

Thanks Keith.

Although not near the record Aboyne has done well today based on the latest data I can find.

A min of -6.1°C and max of 15.4°C gives an impressive range of 21.5°C. That may be as much as we'll see for a while?

Min at Aboyne 2100-0900 was -6.5C (lowest min in the UK and one of the lowest temperatures this winter), must have just popped a little lower between 0600 and 0700 as Viking3 suggested.
