This Evening and Tonight:

Outbreaks of sometimes heavy rain already across western areas gradually spread to remaining areas this evening. Rain becoming lighter overnight, with many western areas turning drier by dawn. Winds also easing. Minimum temperature 4 °C.

Cloudy, with early rain clearing to leave many parts dry for time. However further outbreaks of rain will move into some western areas, perhaps turning heavy and persistent in places. Maximum temperature 8 °C.

Outlook for Monday to Wednesday:

Mainly dry and cloudy Monday, perhaps a few light showers. Tuesday probably becoming wet and windy. Wednesday possibly becoming drier and brighter. Temperatures near or slightly below average, feeling cold.

Weather systems moving in from the Atlantic will continue to attempt to push in from the west, but tending to stall in the vicinity of the UK as they encounter high pressure to the north and northeast. As a result, further spells of rain or showers are expected at times. These may be heavy and persistent, especially in the south and west. Whilst mild conditions are expected to encroach into the south and southwest at times, cold air is likely to be positioned to the northeast, bringing wintry showers at times. Where fronts from the south west do reach the cold air towards the north east, there is the risk of some snow, most likely across hills, but perhaps extending to lower areas at times.

A similar theme is expected to continue as Atlantic frontal systems attempt to push eastwards at times. As the jet stream is slightly further south than normal, the wettest conditions are more likely in central and southern areas. North and northwestern parts of the UK are most likely to be drier than normal. Whilst mild incursions of wet and windy weather are favoured at times in the south and west, colder conditions in the north and northeast will bring an increased risk of wintry hazards, especially where any precipitation from the south west interacts with the cold air.
