Electric Mountain Llanberis (Gwynedd) weather

Headline:

Bright spells, but with showers at times. Very mild.

This Evening and Tonight:

Showers easing overnight, allowing some clearer spells to develop. Mist or fog patches may form in the early hours underneath the lengthiest clear skies. Feeling mild with a slight breeze developing in the far west. Minimum temperature 10 °C.

Friday:

A few bright spells during the morning. Turning increasingly cloudy from the southwest as rain, which may be heavy at times, pushes northeastwards during the afternoon. Remaining mild. Becoming breezy. Maximum temperature 15 °C.

Outlook for Saturday to Monday:

A brighter start on Saturday, though showers possible later. Another fine start on Sunday, but turning unsettled later as bands of rain push eastwards through Sunday and Monday. Feeling fresher.

The start of this period is likely to be largely unsettled and mostly mild, with bands or areas of rain moving across most parts of the UK, although tending to be focused more on western and possibly southern parts. Locally strong winds may also accompany the rain at times. Some drier spells are also likely, the best of these probably towards the east and possibly the north. Where skies are clear and winds light overnight, frost and fog are likely, the fog slow to clear. From around the middle of the month, we may see a transition towards more generally drier weather across the UK, and with this it is likely to turn a little cooler overall, with a greater risk of overnight frost.

Whilst the expected weather patterns during late November are highly uncertain, there is a greater chance of spells of high pressure during this period, bringing more in the way of dry weather compared to the current weather pattern, which also increases the chances of overnight fog and frost. There will probably still be some spells of rain, showers, and stronger winds though, especially in the west. Hill snow is also a possibility, mainly in the north. Overall, near or slightly above average temperatures are most likely, though some colder spells are also possible, especially should any prolonged settled spells develop.
