Antur Stiniog (Gwynedd) weather

Headline:

Wintry showers in the west, frost overnight.

This Evening and Tonight:

Blustery, wintry showers persisting in the west, bringing a chance of icy patches and accumulating snow on hills. Widely clear skies and lighter winds in the east, allow for a widespread frost to develop overnight. Minimum temperature -5 °C.

Thursday:

Ongoing wintry showers in the west. Dry further east with plenty of sunny spells. Cold, but less of a wind-chill effect than Wednesday, with the breeze moderating throughout the day. Maximum temperature 7 °C.

Outlook for Friday to Sunday:

Cold again on Friday, though sunshine for many as showers ease. A change this weekend as it turns more unsettled with rain moving in, but also with temperatures increasing slightly.

Unsettled at first with low pressure, to the east, only very slow clearing. This bringing cloud and outbreaks of rain to many areas, accompanied by strong winds and coastal gales. These more unsettled conditions will probably become increasingly confined to the east, whilst showers in the far north are increasingly likely to turn to sleet and snow. A more settled interlude is possible mid-next week, which may be brief or could last a few days, before a trend towards more changeable conditions associated with Atlantic weather systems. Towards the end of the period, an increasing chance of more settled spells. Temperatures overall likely to be a little below average, with further overnight frosts in settled spells.

There is an increased chance of settled spells developing during early December, bringing more in the way of dry weather, light winds, and increased risk of overnight fog and frosts. This is associated with more frequent high pressure which will probably never be too far away to the north. Whilst spells of wind/rain still remain possible, they are likely to be less frequent than usual at first, but a steady increase in periods of unsettled weather across southern areas in particular seems likely as the period progresses. Overall, above average temperatures are slightly more likely, but colder spells, especially at first and in the north, could still occur. One or more spells of snow cannot be ruled out, should weather systems arriving from the south, push north into colder air.
