Brits could see snow fall across the UK within days, with scientists naming areas where blizzards are expected to hit on Monday November 16 and Tuesday November 17. Sub-zero temperatures are forecast to freeze the country this week, and winter weather is expected to persist into early next week. The first flakes are thought to land on Monday morning around 9am, with intermittent flurries extending into Tuesday afternoon.

Predicting snow accurately is difficult, as the slightest change in conditions can stop it from falling. The Met Office said northern Scotland has the greatest chance of seeing snow on Monday. Its forecast issued early on Friday read: "Unsettled with spells of rain or showers Sunday and Monday. Rain in the south on Tuesday, with some hill snow possible. Brighter with showers elsewhere. Often windy and feeling cold." Earlier on Thursday, Met Office experts said snow was most likely above a few hundred metres, though temporary accumulations could occur as low as 200-300 metres, with around 2-5 cm possible above 400 metres.S1S2

WX Charts has forecast that 47 UK counties could see snowfall: seven in Scotland, 14 in Wales and 26 in England, mostly in rural areas. Northern Scotland again features, as do mid-Wales and most of England from north to south. Counties as far north as Cumbria and as far south as Buckinghamshire are forecast to see some snow across both days. Monday is expected to bring more flurries, while Tuesday could bring more intense snowfall.S1S2
