Bethesda (Gwynedd) weather

Headline:

A cold weekend with ice and wintry showers at times.

Today:

An icy start with wintry showers possible at times through today. These will be most numerous in the west and some eastern regions may remain dry with sunshine. Brisk northerly winds in the west. Feeling very cold. Maximum temperature 5 °C.

Tonight:

Further wintry showers in western regions overnight, leading to the risk of ice and slippery conditions on untreated surfaces. Turning widely frosty with a severe frost in some spots. Minimum temperature -5 °C.

Sunday:

Another cold day with sunny spells and wintry showers. Snow accumulations are likely in places with travel disruption possible locally, perhaps most likely in parts of Pembrokeshire later. Winds easing. Maximum temperature 5 °C.

Outlook for Monday to Wednesday:

Largely sunny and cold on Monday with wintry showers near western coasts. Turning somewhat less cold thereafter with occasional rain or snow. Severe overnight frosts at first with ice possible.

The recent spell of cold, northerly winds should begin to ease by the middle of next week, with snow showers in the north and east becoming lighter and less frequent. However, bands of rain seem likely to gradually move in off the Atlantic and, as these encounter the cold air entrenched over the UK, some further snowfall is possible, particularly in central and eastern areas, with rain more likely in the west. From next weekend, the outlook becomes more uncertain. Most likely is that conditions will be less cold than recently, but there remains potential for further spells of snow, especially in northern and central areas. Further south and west, some milder interludes are possible, with the chance of some heavier rain and stronger winds at times.

The outlook through the second half of January is very uncertain, with no strong indication for any particular weather pattern to dominate. As such, conditions are most likely to be changeable. Spells of wet, windy and mild weather are possible at times, along with colder, drier interludes with overnight frost and fog. Snow and ice remain possible, especially in central and northern parts of the UK, but the chance of these is lower than earlier in the month.
