Sat 10 Jan Wales

A changeable period is expected, with Atlantic frontal systems occasionally affecting the UK, bringing spells of rain, likely preceded by snow in some areas, more especially central, northern and eastern parts. Some significant snowfall is possible in places, particularly on northern hills. These low pressure systems could also bring some strong winds. These will be interspersed with quieter, drier interludes under transient ridges of high pressure, with the potential for frost, and wintry showers along coasts exposed to northerly winds. Temperatures will tend to trend closer to average as the period progresses, mainly in the south, such that the frequency of wintry hazards, especially in the south, may reduce slightly. However, there is a hint late in this period that it may briefly turn widely drier and colder again.
