Cadair Idris (Gwynedd) weather

Headline:

A cloudy and wet start. Gradually turning brighter for some.

Today:

A cloudy morning with outbreaks of rain, heavy over hills and mountains in the north. Tending to become drier and brighter for some into the afternoon, though cloud and drizzle lingering over the hills in the north and west. Breezy. Maximum temperature 23 °C.

Tonight:

Cloud amounts increasing again during the evening, with further rain and drizzle over the hills and around some coasts overnight. Winds easing. Minimum temperature 11 °C.

Wednesday:

After a cloudy start the day ahead should become brighter, mainly away from the west. Feeling warm and humid with the risk of a few showers in the south later. Maximum temperature 24 °C.

Outlook for Thursday to Saturday:

Often cloudy through this period. The risk of some rain at times, mainly in the north. Feeling pleasant in any sunshine that develops, though also rather breezy at times.

Weather conditions are expected to be remain changeable through this period, as a series of Atlantic low pressure systems pass to the northwest of the UK. These will tend to bring some occasional rain or showers, most frequent in northwestern areas where it may also be rather breezy or windy at times. Whilst some rain or showers will be possible across the south and east, here longer drier spells are more likely, under the influence of higher pressure. There is also the chance of some occasional very warm, perhaps locally hot weather, as south or southwesterly winds allow brief bursts of hotter air to encroach from the continent, but probably fairly short-lived and perhaps also accompanied by a few thunderstorms at times.

A continuation of changeable conditions is most likely for the first part of July. The wettest and windiest conditions most likely towards the northwest with a risk of some heavy rain at times, especially over hills. Southern and eastern areas are most favoured for longer drier and more settled spells, although even here some occasional rain or showers will be possible, perhaps thundery. There are signs of more widely settled weather during the second half of July, however this signal is very tentative. Temperatures are expected to be above average for most areas, especially towards the southeast where there will be an ongoing chance of some very warm or hot conditions at times.
