This Evening and Tonight:

The night will be cloudy, and after a cold start well inland, it will turn much milder during the night. There will also be rain in the west later. Strengthening southwesterly winds. Minimum temperature -1 °C.

The morning will remain cloudy, mild and windy with rain, heavier over northwest Highlands. Drier, clearer conditions will reach all parts during the afternoon. Maximum temperature 10 °C.

Outlook for Tuesday to Thursday:

Mild conditions continue with patchy light rain west Tuesday. Outbreaks of rain in the west Wednesday clear briefly overnight before returning during Thursday. Mainly dry, bright east.

High pressure will lie close to the southeast of the UK initially, with generally settled conditions across many parts. Cloud amounts will be variable, with some frost and fog in the south and east, this slow to clear, but some rain in the far northwest. A weakening frontal system looks like it will edge east across the UK over the weekend, 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 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 to produce 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.
