-colour image highlights where snow is lying on the ground. They are created using five channels in the near-infra-red part of the spectrum so things look a little different to what the human eye would see. Snow can be easily differentiated from the white cloud as it now appears in a bright orange

of maritime and continental influences; the air is likely to be warm and predominantly dry, generating fair weather clouds but also some lower cloud bases in moister air to the west. The presence of an upper cold front to the east of England complicates the picture somewhat and will need investigating. What

light rain and drizzle. Staying blustery and mild, and feeling rather humid. Chance of cloud-free hill tops above 600m: Less than 10%, rising to 60% in the east through the afternoon. Low cloud and visibility: A cloudy day with widespread low cloud down to 300-400m, but perhaps even getting down

A noticeable increase in cloud cover across much of the UK compared to recent days

Saturday will bring a noticeable increase in cloud cover across much of the UK compared to recent days, though parts of the south and southwest will enjoy the best of the sunshine. Scattered showers are expected, particularly in western areas, with Northern Ireland likely to see more persistent
