10 Day Forecast for Storey Arms

Page loading ...

Turning colder, but mainly dry with sunshine.

This Evening and Tonight:

A mainly dry night for all, with some cloud and clear spells across the whole of Wales. It will be cold with a widespread frost by the morning. Minimum Temperature -4C.

Saturday:

A frosty start followed by a clear and sunny day. It will feel very cold, especially with the winds picking up through the day. Maximum Temperature 6C.

Outlook for Sunday to Tuesday:

Dry and sunny on Sunday. Turning bitterly cold by Monday, but cloudier with a few snow showers possible in the east. On Tuesday snow showers will affect many parts.

Day 6 to 15

It will stay very cold as we head into March, with sunshine and snow showers. Showers are most likely across eastern and central parts of the UK where accumulations may mount up. Further west, large accumulations are still possible but much less likely. Winds will be light to moderate for most, but across southern Britain strong easterly winds, possibly gales around the coast, will make it feel bitterly cold. Night time frosts will be widespread and severe in places too. There is currently a possibility of more unsettled weather trying to push in from the southwest at times towards the first weekend in March and beyond. This could bring more significant snow and gales to southern parts of the UK but there is currently a lot of uncertainty with this.

Day 16 to 30

At the start of this period it will probably still be cold across the UK, with widespread frost and brisk easterly winds from Continental Europe, making it feel raw. This will continue to bring the risk of significant snow across some southern, eastern and central parts of the UK, whereas in the north and west it should be drier. As we head through the middle of March, there is a lot of uncertainty in the forecast, but it may start to turn more generally unsettled and less cold with wetter and milder weather spreading in from the southwest. In contrast, northern and eastern areas could remain cold well into March.
