Sun 26 Jan East of England

This looks like being and unsettled period across much of the country, but especially for northern and western parts. During Sunday and into Monday, another deep area of low pressure looks likely to move across the UK from the Atlantic, bringing wet and windy conditions to most if not all parts. Further spells of wet and windy weather look like moving east from the Atlantic to affect the UK during the rest of the period too, with drier, brighter spells in between. There is the potential for further weather warnings or even a named storm at some point. Temperatures overall are likely to end up being around or slightly above average, though wind and rain will make it feel chilly, and brief cool spells are likely between weather systems.
