Colne (Lancashire) weather

Headline:

Rain and hill snow overnight, drier for some on Friday.

This Evening and Tonight:

Mainly dry this evening, however periods of rain pushing northwards overnight, turning heavy at times and falling as snow over higher ground. Several centimetres of snow possible by the morning on the highest ground of the Pennines. Turning rather windy. Minimum temperature 0 °C.

Friday:

Often wet with rain and hill snow, the snow confined to the highest ground by the afternoon, with brighter interludes possible, chiefly in the west. Winds easing. Turning somewhat milder. Maximum temperature 8 °C.

Outlook for Saturday to Monday:

Staying changeable with showery rain and hill snow at times. Generally drier than of late but often cloudy with fog possible at times. Largely frost free. Turning windier on Monday.

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.
