The UK could take its first winter punch if temperatures drop towards the end of this week – and for some there is even a chance of snow.
Colder temperatures are accompanied by showers that increase the risk of a winter explosion, even in the south of the Midlands. The mercury will struggle to rise above freezing from Thursday with peaks of around 4C.
Some forecasters suggest a brief, sharp blast from much cooler conditions – although some longer-term forecasts indicate the UK could be shrouded in a blanket of cold air pouring down from the Arctic and Scandinavia.
Low air pressure is likely to take control by Thursday, with a northwesterly wind increasing the cold and could affect how far south and at what level snow falls.
The snow will likely only be on higher ground, with the weather turning significantly colder until Thursday and Friday with temperatures as high as 5 ° C during the day.
Forecaster Brian Glaze, van The Weather Outlook, said: “Wednesday pushes a rain belt to the southeast and fragments. It probably reaches the London area in the course of the afternoon. Bright and colder conditions follow, but showers develop in the northwest. Over high ground they turn to wet snow or snow.
“During the second half of the week, the weather will be quite choppy. All areas are expected to have showers or longer periods of rain. There is a risk of sleet or snow in the northern half of the UK and perhaps on high ground beyond sometimes to the south. “
The With Office The forecasts for Thursday and Friday predict that it will be fresh and restless by the end of the working week.
And the long-range report predicts areas of heavy rain and showers, locally likely with soft hail, sleet and snow, and possibly more widespread snow over some hills and mountains.
It adds: “It is often windy, especially around the coasts, but in quieter nighttime interludes there remains the potential for some irregular frost, isolated fog and freezing rain. Temperatures are expected to remain below average overall.
“Later in this period it can get drier and calmer with the chance that there will be high pressure from the north, with strong easterly winds.”
