Cold air pushes across the UK from the north and temperatures will dip, with daytime temperatures struggling to get above freezing in many places from mid-week onwards.
However, the cold air from the Arctic will also bring brighter conditions, with some dry, sunny spells, particularly away from the coast.
A Cold Weather Health Alert is in place from the Met Office and the NHS.
Today: Wednesday 7 December
Feeling cold. Inland a largely dry day is expected with sunny spells developing. Near coasts remaining rather cloudy with further showers. Breezy near the coast. Maximum temperature 4 °C.
Occasional showers on coasts, these turning wintry. Elsewhere dry, with lengthy clear spells developing, allowing a widespread sharp frost to form. Minimum temperature -6 °C.
Coastal showers continuing, these wintry at times, perhaps moving into Lincolnshire later. Largely dry with sunny spells elsewhere, but remaining cold with temperatures only just reaching above freezing for many. Maximum temperature 2 °C.
Outlook for Friday to Sunday:
Very cold, especially overnight with widespread frosts. Often sunny, however daytime temperatures remaining just above freezing. Showers, wintry at times, predominantly along coasts but perhaps also occasionally inland. Light winds.
