Minimum temperature 3 °C.

A dull and damp day for most with light rain and drizzle at times, most persistent over higher ground. Driest in the east with some bright spells possible. Feeling milder. Maximum temperature 9 °C.

Outlook for Wednesday to Friday:

Staying generally dry. A lot of cloud for most but some sunshine is likely at times. Temperatures near average overall but frost and fog remains possible.

High pressure will lie close to the southeast of the UK initially, with generally settled conditions across many parts. Cloud amounts generally be large, and a little light drizzle is likely in places, which could locally become freezing by Sunday. A weakening frontal system looks like it will edge east across the UK during Sunday and Monday, before high pressure briefly builds back in from the west in its wake. Low pressure then seems likely to increasingly influence the UK weather later in the period, with some rain or showers and windier conditions affecting most if not all parts. Temperatures are likely to be generally a little above average, especially in the north, though more frost and fog patches are likely under clearer skies and lighter winds.

A dominant flow from the Atlantic looks likely through this period, resulting in an unsettled, milder and windier than average period. This is likely to result in areas of rain and periods of stronger winds affecting most if not all parts of the UK at times, though with the wettest and windiest weather probably occurring towards the north and west. However, the potential for brief colder spells with associated frost, ice and snow remains, following any deep lows crossing the region.
