London snow radar: Heavy snow this weekend as two systems battle for dominance – maps

UK weather: Met Office issue warning for heavy rain
Wintry weather has been seen across the UK in recent days, with heavy snow, sleet and icy conditions for much of the country. Now two weather systems will battle it out across the south of England this weekend, bringing sleet, snow and rain to the lower half of the country. Met Office warnings are in place, but will London see more snow?
Met Office Chief Meteorologist, Neil Armstrong, said: “A weather front moves northeastwards across the UK bringing rain which turns to snow as it pushes further north and meets with colder air.
“This system has prompted a number of warnings including a rain warning for Northern Ireland, while snow warnings will be in force for parts of northern England and Scotland.”
Further warnings have today been issued for the south of England and Wales for snow this weekend.
The Met Office yellow weather warning is in place from 3am on Saturday until 6pm the same day for the East Midlands, London and South East England, North West England, South West England, Wales, the West Midlands and Yorkshire and Humber.

Forecasters warn: “An area of rain pushing in from the southwest through the early morning will readily turn to snow in places as it encounters colder air.
“There remains a good deal of uncertainty in how far north the rain and snow will get, before the band stalls and starts to move south again as it eases.”
Up to “1.1 to 2.7 inches (3 to 7cm) of snow is possible to low levels with the potential for 3.9 to 5.9 inches (10 to 15cm) over high ground (above 200 to 300 m), mainly in Wales and the West Midlands.
“There is a very low chance of perhaps as much 7.8 inches (20cm) over highest parts of the Shropshire and Snowdonia.”
Weather maps from Netweather and WXCharts show heavy snow across much of the country this weekend, particularly concentrated around Scotland and the South of England.
Netwether forecasters warn two systems, one on Saturday and another on Sunday will bring more rain, sleet and snow.
These systems will push “in from the southwest across England and Wales over the weekend, but some uncertainty over how far north this will spread with both of these systems.”
On Saturday, a band of rain “preceded by snow on its leading-edge” will spread northeast across Wales, central and southern England through the morning.
Netweather forecasters say this system will “grind to a halt before reaching northern England.”
This band of rain is linked to Storm Justine and will affect southern England and South Wales.
There is a possibility of snow on the leading edge of this system, especially over South Western hills and the higher ground of southern Wales.
Further north clearer conditions will dominate, with temperatures remaining low and with possibly extensive frosts by night.
Later on Saturday, rain, sleet and snow will clear south.
Sunday be bright and dry in the morning before “more rain preceded by snow” will push “from the southwest on Sunday through the afternoon across Wales, central and southern areas.”
There is some uncertainty about how far south or north the rain to snow line will be on both Saturday and Sunday.
Netweather forecasters say some models show snow confined to Wales and southern England while others show the snow further north for north Wales, NW England and the Midlands with rain in the south.
