St Helens (Merseyside) weather

Headline:

Chilly but mostly dry. Milder, but unsettled by the weekend.

Today:

Most of the region will have a dry, albeit rather cloudy day with a brisk and chilly southeasterly wind blowing. There is just a chance that southernmost parts could see some patchy rain developing later on though. Maximum temperature 5 °C.

Tonight:

It looks cloudy and breezy overnight, with a chance of light rain and perhaps some snow at times in the south. Clearer breaks further north later, allowing frost to form. Minimum temperature 0 °C.

Thursday:

Any rain or snow in the south should peter out in the morning, allowing skies to gradually brighten from the northwest as the day unfolds. Remaining chilly, though winds easing. Maximum temperature 6 °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.
