“It’s from Thursday that the snow risk becomes more potentially impactful"

Met Office deputy chief meteorologist Chris Almond said: “While the early part of this week will see some rain, at times heavy, gradually sinking southwards, there’s an increased signal for wintry hazards as we move through the week as cold air from the north moves over the UK.

“It’s from Thursday that the snow risk becomes more potentially impactful, as mild air attempts to move back in from the south, bumping into the cold air and increasing the chance of snow developing on the leading edge.

"While there are still lots of details to work out, the initial snow risk looks highest in northern England and Wales from Thursday. 1-2cm is possible to low levels, with 10-20cm possible over the highest ground within the warning area. This snow will likely gradually transition to sleet and rain later on from the south.”
