Wales weather forecast

Headline:

Chilly with scattered showers mixed with a few sunny spells.

This Evening and Tonight:

Early evening showers soon fade away, leaving a dry and settled evening. Turning cloudier overnight with showers arriving from the north, turning wintry over the hills. Feeling chilly with clear skies allowing frost and patchy ice to form in places. Minimum temperature -2 °C.

Friday:

A chilly start with a continuation of sunny spells and scattered showers, these heavy and wintry at times before easing through the evening. Winds remaining light. Maximum temperature 8 °C.

Outlook for Saturday to Monday:

Drier and more settled over the weekend, with some sunny spells. Still rather chilly with overnight frosts, but feeling pleasant in afternoon sunshine. Cloudier with a few showers on Monday.

UK long range weather forecast

High pressure is expected to be centred to the east of the UK for much of next week. Initially there should be a good deal of dry weather with sunny spells by day, but still the potential for some chilly nights at first. Daytime temperatures will probably start around average, but gradually increase day by day. As we move towards the weekend and into the following week, we are likely to see a gradual transition to less settled conditions. So rain or showers are expected at times, mostly focussed across the south and west at first, then more widely later. With winds predominantly coming from the south or southwest it will also become much milder, possibly warm in places.
