The UK is braced for more wintry weather across the weekend with frost creeping in overnight and temperatures set to plummet as low as minus 6C in some areas.
Forecasters said the “peaks and troughs” of spring will hit most of the country over the next week, with sunny spells and windy intervals expected in most regions.
Gardeners have been warned to keep an eye on their blooms as sub-zero temperatures expected on Saturday night could disrupt flowering.
Met Office meteorologist Simon Partridge said lows of minus 6C were likely in northern regions on Saturday night, before a slightly milder turn on Sunday.
“Tonight will be cold, with widespread frost across the UK. We could well see a number of spots between minus 4C and minus 6C,” he said.
“Typically, everything started flowering and all the gardeners do need to keep an eye for the frost tonight because that will cause issues for some, I’m sure.”
A yellow weather warning put in place by national forecasters for Saturday was lifted, with conditions milder than on Friday.
Some showers are due on eastern coasts across the weekend but temperatures will generally feel less cold because of lighter winds across the country, he said.
Sunshine and dry weather could warm up most parts of the UK on Sunday, but rain is likely to edge in over Northern Ireland and Scotland.
“A wetter and windier day round there, and we could see some strong, possibly gale-force winds around Scotland,” Partridge said.
More unsettled weather is set to hit most of Britain from Monday to Wednesday, with widespread rain and wind expected.
“That’s the difficulty with spring and its peaks and troughs,” Partridge said.
The icy weather this month comes after the UK experienced its sunniest March since 1929.
Northern Ireland basked in 90% more sunshine than average for the month, with a total of 192.5 hours of sun.
Scotland saw 64% more sun than usual, with a total of 160.1 hours, while England enjoyed its sunniest March at 168.1 hours and Wales its fifth brightest with 157.9 hours.
