Today’s snow came thanks to an area of low pressure that tracked further south than forecast.
‘Xanthos’ brought several hours of precipitation, 21.3mm in all to 3pm. Associated precipitation started as rain in Wanstead at 4am, turning to snow at 8am and quickly settling on all surfaces. By the observation time at 9am about 1cm had accumulated as the snow turned heavier.
Snow continued to fall through the day though, because soil temperatures are still relatively warm, the snow thawed from below and accumulations locally were restricted to around 5cms.
There is still a full, slushy cover on lawns at nightfall.
