Penrhiw-Llan (Ceredigion) weather

Headline:

A very cold and frosty start to the new year.

Today:

A rather cloudy morning with a band of patchy rain and hill snow moving southwards. Turning brighter by New Year's afternoon with a few wintry showers following, particularly across the north. Feeling cold, especially in the brisk breeze. Maximum temperature 8 °C.

Tonight:

A mostly dry evening with clear spells. Overnight a band of rain, sleet and snow moves southwards, leading to a risk of ice and some accumulations, especially over high ground. Minimum temperature -3 °C.

Friday:

Rain, sleet and snow clearing south during the morning, with plenty of sunshine following. Feeling cold with perhaps a few wintry showers come the afternoon. Maximum temperature 5 °C.

Outlook for Saturday to Monday:

A cold weekend with further wintry showers at times, especially near northern and western coasts. Plenty of sunshine inland and widespread frosts by night. Remaining similar on Monday.

Cold northerly winds dominant across the UK in the first week of January bring wintry showers (often of snow) to many coastlines (and areas just inland of these) that are exposed to onshore winds. Into the new week more coherent bands of precipitation and thicker cloud will attempt to move in from the west, with a risk of further snow on the leading edge of these turning to rain. Confidence is low in the rate of this return to a more mild Atlantic flow, with a risk of further artic airflows following fronts to resume wintry showers, especially across northern areas of the UK. Temperatures recovering to just below average for most, though further north more likely to return cold at times.

Whilst confidence in details is low, by the start of this period the transition back to westerly winds bringing Atlantic weather systems into the UK is expected to be complete, with temperatures most likely recovering to around or just below average. There is perhaps a weak signal for slowly evolving weather patterns to be more favoured than normal, such patterns increase the chances of frost and fog above normal by night.
