    Any mist and fog clearing, then a dry and increasingly bright day with some sunshine developing for many of us. Not as mild, albeit with light winds for all. Maximum temperature 9 °C.

    Outlook for Wednesday to Friday:

    Turning windier on Wednesday with coastal gales and further rain at times, this likely heavy and persistent by Thursday. Bright and breezy on Friday with sunshine and isolated showers. Mild.
