Welcome to meteorological winter! Yes, the first day of the new season and it is a seasonable start to December with temperatures well below normal in many areas meaning widespread night frost and fog and there are some snow showers around in places too.
It's a cold, frosty and, in places, icy start to the day for many regions with some mist or freezing fog patches but these will generally clear and then for many areas it will be a fine and dry day with spells of sunshine. However, the sun is very weak at this time of year so some of those fog patches may linger well into the day across inland parts of England and Wales keeping temperatures close to freezing. We will still have some scattered wintry showers around northern and eastern coasts, with some showers also affecting parts of western Scotland, Northern Ireland and western Ireland. Temperatures will again be below normal with highs in the range of 2°C to 5°C for many.
Apart from a few showers continuing around windward coasts tonight, clear skies will lead to a widespread and locally sharp frost forming along with some mist and freezing fog again. This takes us into a very cold start to the weekend but there will be plenty of sunshine around tomorrow once any mist, fog and low cloud clears with just a few coastal showers.
