Elidir Fawr (Gwynedd) weather

Headline:

A wet weekend to come.

This Evening and Tonight:

Bands of rain spreading north across Wales this evening merging into longer spells of rain overnight. Occasional clear spells in northern and western areas. Windy at times. Remaining largely frost-free with overnight temperatures slightly above average. Minimum temperature 3 °C.

Saturday:

Cloudy for many with spells of rain through the morning, though tending to become drier with just a few showers by the afternoon. Brightest in the west. Winds gradually easing. Maximum temperature 8 °C.

Outlook for Sunday to Tuesday:

Drier on Sunday with low cloud and fog lingering for some, although most seeing the sunshine break through. Increasingly unsettled early next week with wet and windy weather at times.

Frontal systems over the North Atlantic, steered by a south-shifted jet stream, are likely to approach the UK at times, but tending to stall as they encounter a blocking area of high pressure to the north and northeast. This will result in further spells of rain at times, falling in areas already sensitive to flooding. As these bands of rain spread northwards, some snow will be possible on high ground in northern England and Scotland as they encounter colder air. A subtle shift southwards of these areas of low pressure is anticipated during the second week of February, which may allow a greater chance of colder air to spread across northern UK at least, bringing an increased risk of wintry hazards for a time.

Whilst confidence is lower through this period, a south-shifted jet stream is likely to persist much of the time, steering areas of low pressure towards and south of the UK. This is likely to bring further spells of wet and windy weather, rain most frequent in the south and west, and perhaps also eastern Scotland, with the driest conditions, relative to normal, in northwest Scotland. Some hill snow will be possible at times as the wet weather encounters colder air across northern parts of the UK. Temperatures for the period as a whole will likely be close to average in the southwest, but a little below in the northeast.
