Snow showers, frost and rain are set to strike Britain after widespread freezing temperatures overnight brought one of the chilliest starts to an early May bank holiday.
Temperatures plunged as low as -4.3C (24F) as icy Arctic air flowed southwards, leaving many northern parts with frost and some sleet over high ground in Scotland, the Met Office said.
Katesbridge in Co Down was the coldest spot, followed by -2.4C (27.7F) at Shap in Cumbria, -1.7C (29F) in Sennybridge, Brecknockshire, and -1C (30F) at Loch Glascarnoch in the Highlands.
Wintry showers are expected in parts of Northern Ireland on a chilly bank holiday Monday, as a separate band of showers moves from southern Scotland, Northern Ireland and northern England into central and eastern England.
The lowest recorded temperature for the early May bank holiday Monday is -5.9C (21.4F) on May 7, 2012, at Kinbrace in Sutherland.
Thunderstorms with heavy rain and strong winds are set to batter Britain from Wednesday with highs of just 7-8C in the north and 13-14C in the south all week.
Wales and southern England will stay dry on Monday with sunny spells as rain falls elsewhere.
Temperatures are expected to peak at 14C (57.2F) or 15C (59F) in the south on Monday afternoon, although northern parts will struggle to see double digits as a band of rain pushes towards the south and east.
Pollen levels will be low and the UV index will be moderate.
Met Office meteorologist Simon Partridge said: "We're stuck between high pressure to the west of us and low pressure to the east, which is giving us northerly winds – it's drawing air straight down from the Arctic."
"It's going to be fairly chilly during the day, below average for the time of year, but it's not going to be too bad and the wind's going to be light," Mr Partridge said.
"It will be generally dry, although there is a band of showery rain that's going to slowly move its way from Scotland southwards through parts of Northern Ireland and northern England then eventually into parts of East Anglia.
"That will make it feel a bit cooler through there, but either side of it will generally be dry and bright with sunny spells.
"It will stay mostly dry in the south, where it will be warmest, so Wales and much of southern England will be fine."
The Met Office said a few showers will continue in the evening but most areas will have a dry, cloudy and less cold night than recently.
Frost will be confined to northern rural areas.
Showers will fall in some areas on Tuesday, particularly in the north, while the rest of the country enjoys spells of sunshine.
The sunniest places will be western Scotland and the far south of England.
Wet and windy weather will sweep in from the southwest on Wednesday, bringing heavy and perhaps thundery showers which will continue into Thursday and Friday, the Met Office said.
Met Office five-day weather forecast
Northern Scotland will feel cold with a few wintry showers.
A separate band of showers will move from southern Scotland, Northern Ireland and northern England into central and eastern England.
Wales and southern England will stay dry with sunny spells.
A few showers will continue into the evening but most areas will have a dry, but cloudier and less cold night than recently with frost confined to northern rural areas.

Wednesday to Friday
Wet and windy weather will arrive from the southwest into Wednesday, followed by heavy and perhaps thundery showers which will continue into Thursday and Friday in many places.
Risk of hail and thunder
In its extended forecast for Friday 10 May to Sunday 19 May, the Met Office said: "The unsettled theme will probably continue on Friday, and perhaps into Saturday, with sunshine, showers and perhaps longer spells of rain which will be most likely across the south.
"The showers could be heavy at times, with the risk of hail and thunder.
"Temperatures will start below average for many, with overnight frost possible, but they will recover closer to normal by the end of the weekend.
"From Sunday onwards it looks likely that more settled conditions will gradually become established, especially for eastern areas, and with temperatures improving with any sunshine.
"West and northwestern areas are at greatest risk of having further rain and strong winds at times, but there will be some drier and more settled interludes here too."
