This week winter will arrive in earnest in the UK, driven by a large area of high pressure over Iceland that will drag Arctic air southwards.
As this cold air descends over the UK on Tuesday, northern Scotland will experience the first signs of this wintry weather, with daytime temperatures forecast to be barely above freezing, alongside some possible sleet and snow showers throughout the day. The cold front will make its way further south over the course of Wednesday, pulling temperatures to well below the seasonal norm.
