Thu 27 Mar London and South East England

The final week of March into the start of April looks to be characterised by a slowly evolving, but changeable weather pattern. Initially, a dry interlude is likely with spells of sunshine across many areas. With time, these drier conditions will become more favoured across the south. Further north and northwest, there is a greater chance of rain or showers at times, these accompanied by windier spells and a chance of gales for parts of the far northwest. There is a small chance that these wetter, more unsettled conditions could become more widespread for a time. Temperatures will probably pan out close to average overall, though chilly nights remain possible where clear skies coincide with light winds.
