Headline:

Largely dry and cold.

Tonight:

Increasingly cloudy overnight with outbreaks of light rain or drizzle spreading south as it also turns breezy. Feeling chilly under early cloud breaks, but turning milder than of late. Minimum temperature 2 °C.

Remaining windy and cloudy through Tuesday. The cloud thick enough for further patchy rain at times, this turning heavier and more persistent in the evening. Feeling milder than recent days. Maximum temperature 12 °C.

UK long range weather forecast

Wintry precipitation moving eastward overnight Friday. Snow possible at low-levels across northern England and Scotland for a time, before turning to rain away from high ground. Further south snow likely confined to high ground. Brighter showery conditions following, these frequent and heavy in the northwest, wintry over high ground. Remaining windy, with gales possible in exposed northern areas. Temperatures near normal. Continuing unsettled through the rest of this period with spells of wet and windy weather, interspersed with brighter interludes accompanied with showers. Likely the wettest conditions to be in the west and northwest, and drier conditions in the south towards the end of the period. Often windy with a risk of gales at times, especially in the north and northwest. Often mild, with the potential for brief colder interludes.

Updated:

Overall, through this period it is expected to be unsettled and changeable with milder and wetter than average conditions for most, bringing a risk of stormy conditions. Perhaps turning more settled in southern regions for a time nearer the start of this period, which will increase the risk of frost and fog when skies clear overnight. Temperatures on the milder side for much of this period, but some short lived colder spells are possible.
