10 Day Forecast for Neuadd Reservoir

Page loading ...

A damp start, but brighter spells developing through the day.

Today:

Breezy and rather cloudy with occasional rain or drizzle through the morning. Generally brighter in the afternoon, with winds easing too. Feeling warm and humid, especially in any sunshine that develops. Maximum Temperature 22C.

Tonight:

A mostly dry night with clear spells at first. Cloud increasing during the early hours, with a few spots of drizzle possible, mostly over the higher ground. Mild. Minimum Temperature 13C.

Monday:

Mostly cloudy, but some bright or sunny breaks will develop at times during the afternoon. A few light showers are also possible. Staying humid and feeling warm once again. Maximum Temperature 24C.

Outlook for Tuesday to Thursday:

Humid and often rather cloudy on Tuesday. However, feeling warm in any spells of sunshine. A band of rain will move south late Wednesday into Thursday, with fresher weather following.

Day 6 to 15

Thursday is likely to see a fresher day across the UK with a mixture of sunshine and showers. Frontal cloud and rain may linger across southern England for a time but should clear the UK completely by the end of the day. Some good spells of sunshine developing across the south with occasional heavy, blustery showers in the north. Through the rest of the week and weekend there will probably be a good deal of dry, bright or sunny weather, especially in the south, while the far west and northwest will have some thicker cloud and rain at times. This weather pattern is quite likely to continue through the rest of the period, with temperatures probably around normal, but perhaps rather cool in the north and northwest.

Day 16 to 30

During this period it looks likely that the weather pattern will only change slowly. Areas of high pressure and associated settled weather are likely to dominate across the south and southeast, bringing generally dry and bright weather here. More changeable conditions with outbreaks of rain and strong winds are likely across the north and northwest, perhaps extending southeastwards at times. Through September, confidence in the forecast decreases. However, we will probably see longer dry and settled spells at times, these perhaps becoming more dominant than previously in the north and northwest. Temperatures by day are likely to be generally warmer than average, but there will be an increasing chance of chillier nights.
