Following a harsh cold snap, temperatures in the UK are expected to rise sharply again next week.
Snow is expected over the weekend, and temperatures might drop as low as -4C overnight, on top of torrential rains today – but then things could turn around miraculously.
A shift in pressure and wind direction should result in bright sunlight and calmer conditions as temperatures progressively rise before peaking in the upper teens next Friday.
BBC meteorologist Ben Rich said: “Through next week, high pressure will be with us at first. That rather chilly air in place. But it looks likely that high pressure will tend to slip its way eastwards, low pressure trying to slip its way in from the Atlantic and a change in the wind direction again.
“Back to southerly winds and so it looks like as we head through next week those temperatures will steadily climb once again. Not quite as warm as it has been but not quite as chilly as it will be over the weekend.”
Mr Rich said London is hitting 16C each day between Tuesday and Friday, while other regions saw similar rises and bright sunshine.
It comes after the Met Office shared more details on this weekend’s snow forecasts with the UK set to see the “first signs of winter”.
Snow will fall amid sleety showers on higher ground across Scotland on Saturday afternoon, forecasters believe, because temperatures are dropping north of the border.
The mercury will also plummet across the rest of the UK and the south of England, in particular, will see a dramatic change in the balmy weather experienced last weekend.
Visitors to Kew Gardens in London, for example, basked in near 26C heat on Saturday.
Meanwhile, the Met Office has issued a yellow weather warning for heavy rain and high winds in Wales and the South West of England until 8 p.m. today, predicting floods and traffic disruption.
The National Weather Service says that flooding on roadways will cause longer travel times and that a few homes and businesses will be flooded.
