Sunday 31 Jan - Tuesday 9 Feb
After a very cold but bright start to Sunday, rain will move in from the west later. Going into next week, unsettled conditions look likely to dominate, with low pressure systems moving in off the Atlantic. The weather will be changeable. Periods of rain or wintry showers, and strong winds are likely, especially in the west, with brief more settled spells in between. Westerly or southwesterly winds during this period will bring milder temperatures to most areas, but occasional interludes of cold northerly winds are possible. It will be on this boundary between colder and milder airmasses where any snowfall to lower levels could possibly occur. Towards the end of this period, we may see high pressure build over the north of the UK, bringing colder temperatures and wintry outbreaks.
Tuesday 9 Feb - Tuesday 23 Feb
Although confidence at this range is low, current signals suggest that high pressure could be positioned over the north of the UK during this period. This would likely bring wintry outbreaks and colder than average temperatures to northern areas, as well as increasing the likelihood of more widespread cold spells. Any periods of milder, unsettled weather are more likely to be confined to central and southern areas, where greater than average rainfall is predicted. There is a continued risk of significant snowfall events on the boundary between colder and milder airmasses, with snow possible to low elevations.
