Weather: Mother's Day Temperatures May Hit 20C
The arrival of British Summer Time at the weekend is set to coincide with a period of warmer weather for many parts of the UK.
Clocks go forward at 1am on Mother's Day this Sunday, meaning we lose an hour's sleep but get longer, lighter evenings.
Temperatures are set to climb to around 13 to 17C (55 to 62F) on Saturday.
And they could reach as high as 15 to 20C (59 to 68F) on Sunday, when we lose an hour's sleep as British Summer Time arrives.
However before that, it is expected to feel quite cold in the UK due to a chilly wind coming from the east.
Plenty of showers are also expected, some of which will bring snow to high ground.
Then, by the weekend, the wind is set to change to a more southerly direction which will bring in warmer air.
Sky News weather forecaster Isobel Lang said: "This week, our weather pattern will switch from the usual prevailing wind direction to an easterly wind bringing in air which has travelled over a chilly North Sea.
"Although not exceptionally cold there will be a chill to the wind and it'll feed in plenty of showers - some of which will bring snow to high ground, especially overnight.
"This easterly will last until the weekend before turning more southerly. It'll draw in warmer air across us and and the warmth will be very welcome."
However Lang cautioned: "Not everyone will enjoy some sunshine, though, with the east coast of Scotland looking cooler and duller and southwestern parts of Britain set for some showers."
Meanwhile, in the decades to come there are expected to be sharp contrasts in seasonal weather for the UK as climate change sends summer temperatures soaring.
Scientists expect powerful heatwaves such as the one that hit continental Europe in 2003 to be commonplace by the 2040s.
But there is no evidence that winters will become generally milder, say the experts. Despite the summer heat, people will still have to plan for the occasional very cold winter, as happened in 2011.
