Accurately predicting whether there’ll be snow or not in two weeks time in the British Isles in December is a bit like trying to pin diarrhoea to a wall.
Said nobody ever.
Maybe not with those exact words, but essentially I’ve said that many, many times. I may use that phrase in the future, though.
My phone weather app for the 19th is probably as close as anything, temp 9° to 13°, with 80% chance of rain. I can remember heavy snow in 1962, 1982, and… that’s about it. But I live in Wessex, in the south west. No, wait, there was some snow in January 2013, it was dreadful, all of an inch or so, couldn’t get out of the house!
