Mevagissey (Cornwall) weather

Headline:

A bright start for some, wet and increasingly windy later.

Today:

Many places will start fairly bright with sunny intervals but soon becoming wet in Cornwall with periods of heavy rain spreading eastwards through this afternoon. Risk of localised flooding. Turning windy with a chance of coastal gales by this evening. Maximum temperature 10 °C.

Tonight:

Wet and windy for many this evening and overnight with periods of heavy rain, but also occasional drier and clearer spells, especially later. A mild night with coastal gales possible. Minimum temperature 6 °C.

Saturday:

Cloudy for many with spells of rain through the morning. Tending to become drier with just scattered showers by the afternoon and brightening up in the west. Winds gradually easing. Maximum temperature 9 °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.

Largely unsettled weather is expected to begin, bringing showers or longer spells of rain for many places. It may also be rather windy at times, especially towards the south west. Towards the northeast, colder conditions will remain nearby, with the risk of colder air pushing further south west at times, increasing the chance of snowfall. Although snow is more likely over high ground, some snow to lower levels could not be ruled out. Temperatures will be close to average for most, but perhaps rather cold in the northeast. An often brisk wind will accentuate the colder feel too, especially for coastal districts. As we move through the forecast, confidence lowers between whether milder air from the south west will dominate or colder air from the east moves more bodily in.

Something of a north-south split seems quite likely at first, with low pressure to the south and high pressure to the north, before a potential change back to more of a southwest-northeast split. With the jet stream likely further south than normal, the wettest conditions are more likely towards the south. Northwestern parts of the UK are most likely to be drier than normal. Whilst incursions of wet, windy and milder weather are favoured at times in the south and later the west, colder conditions further north will bring an increased risk of wintry hazards, especially where any precipitation from the southwest interacts with the cold air. The colder conditions may affect all parts at times, more especially early in this period.
