St-Athan (Vale of Glamorgan) weather

Headline:

Feeling colder with sunshine giving way to mostly cloudy skies.

Today:

Dry this morning with sunny periods. More in the way of cloud developing through this afternoon but staying largely dry. Isolated showers in the north by this evening. Breezier than yesterday and feeling colder. Maximum temperature 9 °C.

Tonight:

Showers pushing southwards this evening, these heaviest in the north and west, falling as snow and hail over the highest ground. Frost and ice possible away from windward coasts. Breezy. Minimum temperature 0 °C.

Wednesday:

A changeable day with broken cloud, brief sunny intervals and a chance of showers. These could be heavy and wintry, especially over hills. Brisk northerly winds in the west. Chilly. Maximum temperature 8 °C.

Outlook for Thursday to Saturday:

Staying on the cold side through this period with overnight frosts possible. A mixture of cloud, sunny/clear intervals and showers, wintry on hills, though these easing by the weekend.

The weekend will continue on a cool theme, but with the high pressure to the north becoming more dominant it should lead to a reduction in shower activity seen on previous days. So there should be a good deal of dry weather with plenty of sunshine by day, but still some noticeably chilly nights with frost fairly widespread. The odd fog patch is possible in the north, and a brisk breeze across the south will make it feel notably chilly here on Saturday. Next week is likely to see a gradual transition to less settled conditions as the high likely withdraws to the east. So rain or showers at times, mostly focussed across the south, the north perhaps staying largely dry and it is also likely to become much milder.

Confidence is low, but through the remainder of March changeable weather patterns are most likely. This means periods of unsettled, wet and windy weather interspersed with some drier and brighter spells. Into early April, there may be a transition to more-frequent drier and more settled spells. Temperatures will probably be above average overall.
