Halliwell (Greater Manchester) weather

Headline:

More settled this week, with frost and fog overnight.

This Evening and Tonight:

Isolated light showers this evening, but all areas becoming dry overnight with occasional clear spells. Winds easing, possibly allowing patchy mist and fog to develop in places later, this most likely in Cumbria. Cold with a frost developing in places. Minimum temperature -2 °C.

Tuesday:

A dry day with broken cloud and sunny spells. Any fog may be very slow to clear in the north, keeping it cold. Otherwise chilly but winds lighter than Monday. Maximum temperature 6 °C.

Outlook for Wednesday to Friday:

High pressure continues to dominate, bringing a mixture of cloud and sunny spells by day, and a chance of frost and fog by night. Winds remaining fairly light.

High pressure will likely weaken into the weekend, allowing occasional bands of rain to make progress southeastwards across parts of the UK. While there may be an attempt for high pressure to rebuild at times, especially in the south, the more likely scenario is for an unsettled regime to dominate for much of next week, with occasional spells of rain followed by blustery showers, these most frequent and perhaps wintry at times in the northwest. It may be quite windy at times too, especially towards the north, while southern areas have a greater chance of some lengthier drier and perhaps more settled spells, although even here it may still be rather breezy. Temperatures will vary around average, with oscillations between colder and milder interludes.

Mainly unsettled conditions appear likely for most, with spells of wind and rain followed by showers affecting most areas but especially the north and northwest of the UK. Some sleet and snow is also likely at times, especially on high ground in the north. However, there are also some signs that more settled conditions are possible at times, these perhaps most likely across the south late in December or into early January. Temperatures are likely to be around average overall, with any more settled interludes bringing a risk of frost and fog.
