Helston (Cornwall) weather

Headline:

Some heavy rain today. Turning milder by the weekend.

Today:

Wednesday will be a cloudy and breezy day with outbreaks of rain and drizzle, which could turn heavy and persistent at times, giving a risk of localised flooding. It will be relatively mild, but feeling colder given the unpleasant weather. Maximum temperature 9 °C.

Tonight:

It will be a rather cloudy and often breezy night with further outbreaks of rain, though this should ease a little later, perhaps with some clearer breaks in the west. Minimum temperature 1 °C.

Thursday:

Rain could take a while to peter out in the east on Thursday, though brighter breaks, along with a few showers should gradually extend to most areas from the west. Maximum temperature 8 °C.

Outlook for Friday to Sunday:

Overnight frost will clear on Friday morning, and thereafter it will turn much milder for the weekend. The weather will remain unsettled though with rain and brisk winds at times.

Quite changeable as Atlantic frontal systems track near or across the UK at times, bringing spells of rain, heaviest and most prolonged over high ground in the west and/or northwest, with comparatively small accumulations in more sheltered eastern and southeastern areas. It will often be quite breezy or windy, the strongest winds typically in the west or northwest. With a west or southwesterly flow tending to dominate, temperatures will likely be near or above average much of the time, especially over this weekend with some very mild conditions expected before a gradual downward trend through the final week of February back closer to average.

Confidence is rather low through this period with regards to the weather patterns affecting the UK. The most likely outcome is a continuation of rather changeable conditions, with low pressure systems tending to pass close to or to the northwest of the UK, bringing occasional spells of wet and windy weather, especially in the north west. High pressure to the south may build across the UK at times to bring some drier, quieter interludes, this probably most frequent in the south and east. Temperatures are likely to be near or slightly above average for the period as a whole, though some relatively short-lived interludes of colder conditions remain possible.
