There's definitely time for an official 20c. Which would be insane. Remarkable day in the Highlands
Remarkable, as you say! Torro says the old date record for the 28th Jan is:
15.4°C Burghill (Herefordshire) 1887
Stratfield Turgis (Hampshire) 1887
15.1°C Monks Wood (Cambridgeshire) 2018
15.0°C Kinlochewe (Highland) 1966
15.0°C Glastonbury St Dunstans (Somerset) 1993
Beating the date record by 3.8C is just plain nuts.
