(Duj) It was a sunny day with snow on the ground and a light easterly wind and it just wouldn't warm up. The reason lay in the air above, an import from north-west Russia. Even the high June sun falling on dry ground would have made little impression on that column of frigidity so the January sun slanting in on a snow surface had no chance. AFAIK my recording was the lowest in the country (unofficial) but if there'd been a weather station at the top of the North Downs, nearly 900 ft, it would have been colder still, the opposite of what normally happens when it gets very cold. The temperature was below freezing continuously for 11 days and stayed below -5°C for 3 days. The UK record for a low max is -19°C (Braemar, Scottish Highlands, 10/1/82). Nothing could move; all the diesel had waxed out.
(Rosie) Don't expect any short term communication. The BoM forecast for our Penrith. As a rule of thumb knock off 2ºC for Chateau Duj. Image here As I type it's just after 1430hrs and 38.0ºC outside in the shade.
