Mynydd Perfedd (Gwynedd) weather

Headline:

Turning very warm for some over the coming days.

This Evening and Tonight:

A largely fine evening towards the southeast, but remaining rather cloudy across the north, which will spread southeastwards overnight. Some light rain and drizzle possible over the hills, but most places staying dry. Minimum temperature 12 °C.

Sunday:

After a cloudy start, cloud will start to lift and break through the morning. Prolonged sunny spells will develop with some warm sunshine during the afternoon, particularly in the south. Maximum temperature 26 °C.

Outlook for Monday to Wednesday:

High pressure will bring a settled and increasingly sunny and very warm spell of weather. Some cloud may affect coastal areas at times, with sea breezes also developing.

High pressure will continue to prevail across England and Wales, likely extending its influence into the northern UK for a time. This will continue to bring dry and very warm weather across England and Wales, but there is an outside chance of the odd localised thunderstorms at times. High pressure may extend northwards to bring periods of drier and warmer weather to most of Scotland and Northern Ireland too. Winds will be light to moderate for most. Temperatures will be widely very warm at first, although not as hot nor humid as seen in June. There are signals for the heatwave to ease back to more normal summer temperatures in the week commencing Monday 13 July.

High pressure is more likely than low pressure for the rest of July, probably bringing settled and drier conditions. Occasionally this dry and warm weather could be interrupted by outbreaks of rain and stronger winds, which will be more probable in the north or west. As is typical for the time of year, there is a risk of heavy, thundery showers during any warm spells. These conditions are likely to persist through to the start of August, with unsettled interruptions perhaps becoming more common, but confidence at this range is low. In any case, temperatures are likely to be above average overall, with a greater than normal chance of hot conditions developing at times, especially in the south.
