Pen Y Fan (Powys) weather

Headline:

Staying dry and bright to end the weekend.

This Evening and Tonight:

Plenty of evening sunshine on offer this evening leaving long clear spells across the country overnight. Under clear skies temperatures will be allowed to rapidly fall away, with a rural frost possible. Minimum temperature 1 °C.

Sunday:

Another chilly, bright start with plenty of sunshine on Sunday. Some patchy cloud through the afternoon may lead to a very isolated light shower. Temperatures around average. Maximum temperature 13 °C.

Outlook for Monday to Wednesday:

Showers move westwards across the country through Monday, clearing later. A dry interlude follows, before more rain develops on Tuesday and Wednesday. Temperatures nearer average, though possibly windy later.

A changeable if not unsettled spell of weather will affect the UK through most if not all this period, with spells of wet and windy weather arriving from the Atlantic followed by drier though still showery interludes. It is possible that stormy weather may also develop at times. However, there is a chance that higher pressure may build near the UK again around the end of October, bringing a quieter spell of weather for a time. Temperatures are likely to be near or a little above normal overall, with mild spells likely at times, especially towards the south. In between frontal systems, and if pressure does build at the end of the period, colder nights are possible, with a touch of frost.

This period is highly uncertain, more so than normal, but overall it seems more likely than not that the UK weather will be dominated by westerly or southwesterly winds from the Atlantic during this period, with areas of potentially deep low pressure often affecting the UK at times. This will result in spells of wet and windy weather followed by drier but still showery interludes. Stormy conditions are also possible at times. High pressure may attempt to build across the country at times, this perhaps more likely early in the period, but any settled spells are likely to be short-lived. Temperatures are likely to be near or a little above average overall.
