Rhobell Fawr (Gwynedd) weather

Headline:

Turning increasingly wet and windy overnight

This Evening and Tonight:

Remaining largely settled this evening, with clear skies and light winds allowing pockets of frost and fog to form. Turning milder and increasingly cloudy overnight with winds picking up from the west by dawn. Minimum temperature 2 °C.

Wednesday:

A wet and windy day as a band of prolonged rain spreads eastwards, bringing heavy downpours. Coastal gales likely with travel disruption and localised flooding possible. Maximum temperature 10 °C.

Outlook for Thursday to Saturday:

Remaining unsettled on Thursday with further heavy and disruptive rain. Friday brings brighter and drier conditions, with occasional showers, before another rain band moves in on Saturday. Often breezy.

Showers or longer spells of rain are likely to continue at first for many parts of the country, perhaps heavy at times, but gradually over the weekend the weather is expected to become more settled. Scotland and Northern Ireland are likely to see this change first, with spells of rain perhaps slower to clear further across the south. Into the following week, high pressure is expected to become more widely established. Winds will be light and clearer skies are likely, however this does not rule out the odd shower, especially around coasts. High pressure and settled weather will result in temperatures falling to closer to average, with overnight frosts and morning fog which could be slow to clear.

High pressure will probably remain influential across the UK during this period. This means an increasing likelihood of dry weather compared to the winter so far. Despite the greater signal for settled weather, showers or occasional bands of rain are still possible at times, especially later in the period towards January. These could be wintry in nature. Temperatures are expected to be close to normal for the time of year.
