This Evening and Tonight: Any showers should become confined to the Lincolnshire coast this evening, then a mainly dry night to follow. However, cloud breaks and light winds will allow some frost and a few freezing fog patches to develop by morning.
Thursday: After a cold start with the odd freezing fog patch, Thursday should be mainly dry and bright with some sunny spells and light winds.
Outlook for Friday to Sunday: Becoming colder into the weekend with increasing wind chill as winds turn easterly and strengthen. Widespread overnight frost, and an increasing risk of snow showers later on Sunday.
