.   Why can't I find the fog map layer? We have had a significant amount of feedback regarding Fog Map Layers. Fog has traditionally been on a combined map layer with cloud base. Having had feedback about this map layer we will bring forward implementation of a map layer to highlight where fog is forecast

northern and western areas, allowing a widespread frost to develop from Wales northwards. Outlook for Tuesday Tuesday brings variable cloud and mostly dry conditions, with clear or sunny spells, particularly inland across western and central areas. Scattered showers will continue along windward

. Elsewhere, expect variable cloud cover with some sunny spells and showers, which could be locally heavy in the south and west, with a risk of isolated cumulonimbus and thunderstorms. Gales are likely for exposed coasts in the north and east, and blustery winds will affect many inland areas at times

, and simultaneously capture cloud-scale motions and long-range atmospheric flows. At sub-km resolutions, turbulent motions are partially resolved. This means some parts of the flow can be represented directly by the dynamical equations of the model. Meanwhile finer-scale motions still need

January 2020 The averaging period used for the following assessment was 1981-2010. At the start of January, high pressure lay over southern parts of the UK, bringing settled weather but generally with plenty of cloud. This gradually moved away south-eastwards allowing frontal systems in from

communication campaign highlights have included: • WeatherReady - an all-year-round campaign run in partnership with the Cabinet Office to help individuals, families and communities prepare for and cope with severe weather. Two key bursts of activity took place in the summer and winter. Part
