Skomer Island (Pembrokeshire) weather

Headline:

Chilly with some rain and snow. Milder later this week.

This Evening and Tonight:

It will be largely dry this evening, with a slight frost forming under cloud breaks, especially in the north and east. The cloud will tend to thicken overnight, bringing patchy rain into southern and western parts, and winds will strengthen. Minimum temperature -1 °C.

Wednesday:

Wednesday will be a cloudy, chilly and rather windy day. Outbreaks of rain with snow in places, will also extend northeastwards across the country as the day unfolds. Maximum temperature 6 °C.

Outlook for Thursday to Saturday:

Rain and snow clearing to leave a mostly dry day on Thursday, with lighter winds. Turning much milder during Friday and Saturday, though some wet and windy weather at times.

Quite changeable as Atlantic frontal systems track near or across the UK at times, bringing spells of rain, heaviest and most prolonged over high ground in the west and/or northwest, with comparatively small accumulations in more sheltered eastern and southeastern areas. It will often be quite breezy or windy, the strongest winds typically in the west or northwest. With a west or southwesterly flow tending to dominate, temperatures will likely be near or above average much of the time, especially over this weekend with some very mild conditions expected before a gradual downward trend through the final week of February back closer to average.

Confidence is rather low through this period with regards to the weather patterns affecting the UK. The most likely outcome is a continuation of rather changeable conditions, with low pressure systems tending to pass close to or to the northwest of the UK, bringing occasional spells of wet and windy weather, especially in the north west. High pressure to the south may build across the UK at times to bring some drier, quieter interludes, this probably most frequent in the south and east. Temperatures are likely to be near or slightly above average for the period as a whole, though some relatively short-lived interludes of colder conditions remain possible.
