A windy warm sector across the south with gusts to 62 mph in south Wales with dew points of 14°C and temperatures of 16°C along the south coast. The air temperature is only 0.5°C on Great Dun Fell, so I imagine that the tops of the hills in the north are getting a covering of snow as those further north have.
The Mumbles lighthouse is very exposed in a gale from the south or southwest, but so are the towns and cities that hug the coastline along that part of the coast of south Wales. I can’t find an explanation of the name from a quick search of the internet which may be lost in the mists of time.
