Wed 26 Mar South West Scotland and Lothian Borders

The final week or so of March to the start of April looks to be characterised by a slowly evolving, generally changeable weather pattern. Initially a more widely dry interlude seems likely but with time these drier conditions become more favoured across the south, where overnight fog is also a possibility. Further north and northwest, there is a greater chance of rain or showers at times, these accompanied by windier spells with a chance of gales for parts of the far northwest especially. There is a small chance that these wetter, windier conditions may 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.
