After residual showers during the day that have left standing water – as well as any thaw of lying snow, with temperatures forecast to drop widely into minus double didgits tonight, severe ice can be expected. Large parts of the country will endure a very icy conditions for the Tuesday morning rush hour. Most major towns and cities will fall to -5°C at least in many locations with temperatures potentially dropping to as low as -12°C/10F by the early hours in rural parts of the midlands, northern England and Scotland. The exceptional to the severe frost will be the far SW of England, the west coast of Wales & parts of Northern Ireland, here extra cloud will hold temperatures up.
The rest of the week will remain cold with a risk of further snow. Tuesday will be a freezing day for almost all places way from the far SW & Northern Ireland. Later in the day, rain falling into very cold air could cause DANGEROUS ice pellets & freezing rain, causing a severe ice risk tomorrow night. Wednesday will turn slightly less cold in the south, however later in the day heavy wintry showers will fall in the north west, giving a further risk of ice/snow, especially on high ground in the north. Although there doesn’t look like being any more significant, widespread disruptive “nationwide” snowfall this week, there’s certainly a chance of some patchy snow, that risk extending southwards from the north on Wednesday however
