Cadair Idris (Gwynedd) weather

Headline:

Another rather cloudy day with patchy light rain beneath the thickest layer and persistent hill fog across the mountains. Some bright or sunny intervals developing in the northwest, especially in Gwynedd and Anglesey. Maximum temperature 12 °C.

Tonight:

Any clear spells filling in leaving another cloudy night. Remaining largely dry but the odd spot of drizzle is possible over higher ground. A fairly mild night. Minimum temperature 7 °C.

Saturday:

Another predominantly dry and cloudy day but sunny intervals breaking through in places. The chance of some drizzly rain developing later, especially by the evening. Feeling rather cool. Maximum temperature 12 °C.

Outlook for Sunday to Tuesday:

Cloudy and damp at first on Sunday, brighter later. Generally dry on Monday and Tuesday with sunny spells though cloudier at times. Chance of frost and fog overnight.

High pressure from early in the week likely reducing its influence during the middle of next week though to an uncertain degree. Likely turning cloudier again across many areas with a chance of showers or longer spells, most probable in parts of the north and east. Southwestern areas have the greatest chance of maintaining largely dry conditions. Temperatures around average but with a greater chance of mild conditions in the northwest and below average temperatures in the southeast. During next weekend and into the following week there are signs that the influence of high pressure will decline to the west. This means northern and eastern areas remain most likely to see more unsettled conditions. This also increases the likelihood of a spell of northerly winds and colder conditions.

Signals vary in prevailing weather patterns through this period but likely more unsettled than during early November. There is a greater chance of more mobile weather patterns which would see Atlantic systems periodically move across the country. These bringing some wetter and windier interludes followed by drier periods. Some colder interludes are possible but overall temperatures more likely to be around or above average.
