BBC Weather meteorologist Carol Kirkwood warned Tuesday is to kick-off with persistent snow across lower grounds across northern and western parts of the UK before lifting off later in the morning to give way to thundery showers. The snowfall overnight and freezing temperatures are expected to leave behind icy roads, with Ms Kirkwood advising commuters to beware of ice and sleety showers later in the day. The BBC Weather forecaster said: “We have snow today even at lower levels. That snow level will tend to lift as we go through the day but if you are travelling across northern and western parts of the UK, including England and Wales, watch out for ice.
“There’ll be some snow on the higher grounds, particularly so in Scotland and Northern Ireland. This is where we had the rain and the snow, the blue is where we had the rain, the white indicates the snow – a lot of this will be in the hills but some of it will be at lower levels.
“If you’re travelling early this morning in the southwest of England, there will be a lot of dry weather, there’ll be some showers – some of those will be sleety – across parts of the Moors and Tors, on the top of the hills in Wales we’re also going to see some snow as we could on the top of the hills in northern England.”
Ms Kirkwood continued: “Perhaps in some of the heavier bursts will see some sleet at lower levels but there is the risk of ice.
“Northern Ireland, you’ve got the snow at lower levels in parts at the moment as in parts of Scotland and that will tend to lift up into the hills as we go through the course of the day.
“Then it will be rain showers you’ll see at lower levels. Through the day, where we’ve got the showers a lot of them will be of rain on higher grounds, even in the southeast. We can see some of that falling as sleet. Gusty winds today, it is going to feel cold.
“Our temperature range is 4C in the north to about 8C in the south but when you add on the effect of the wind, it will feel more like 4C, for example, where we had the 8C in London.
“Through the day some of those showers will not just be heavy, they’ll also have some hail and thunder and lighting embedded in them.”
BBC Weather expects gusty winds to cause temperatures to feel even colder as we head through the evening, resulting in a further temperature drop overnight and more ice in the early hours of Wednesday.
Ms Kirkwood added: “As we head on through the day and into the evening, the wind is still strong across the southwest of England and the English Channel, and through the night, we’ll still be looking at gusts and winds wherever you are.
“Still a lot of showers and still some snow on the hills. Temperature-wise, lots of us will be roundabout freezing or just below so, once again, the risk of ice. You may see some pockets of frost as well, if you’re sheltered from the wind.
“We have a transient ridge of high pressure in southern areas, we’ve got this weak front coming our way from the Atlantic.
“Call it weak is perhaps misrepresenting exactly what’s it going to do because it may well clip Northern Ireland with some persistent rain and the same for Scotland, preceded by some snow.”
