10 Day Forecast for Neuadd Reservoir


Turning more showery.

This Evening and Tonight:

It will remain dry for many this evening across Wales with some clear spells overnight. A band of showers will arrive from the west towards dawn. It will remain rather breezy but mild. Minimum Temperature 6C.


Monday will bring plenty of sunny spells and a scattering of showers, mainly in the morning. Clear spells overnight will allow a touch of frost in the east. Maximum Temperature 11C.

Outlook for Tuesday to Thursday:

After a chilly start it will be dry and bright. It will remain bright and breezy through Wednesday and Thursday with some patchy rain over hills at times. Very mild.

Day 6 to 15

Friday is likely to be mild but breezy across the UK with many places dry and sunny. The southeast may see some early mist and fog, but also the best of the sunshine and very mild in places. The far northwest could see some rain and stronger winds; generally cloudier, more changeable here. This northwest-southeast split in conditions is likely to be maintained through the weekend and into next week. Any spells of rain from the northwest will tend to weaken as it moves southeast, bringing cloudier spells. Dry, settled conditions are likely to dominate through the end of February away from the far northwest; overnight frosts are possible. By early March we are more likely to see Atlantic fronts crossing the UK bringing stronger winds and rain at times.

Day 16 to 30

By early March there are signals for Atlantic fronts crossing the UK, bringing a mixture of wet and windy weather to many parts, but also intermittent drier spells. Snow remains possible over higher ground in the north. There are weaker signals for snow to lower levels elsewhere should a cold easterly develop; this remains a small possibility. However, milder conditions remain more likely, although occasional overnight frosts remain possible.
