Tue 18 Nov Wales

All parts of the UK are likely to start off on a rather cold but bright note, with some sunshine. However, some showers are likely to pepper northern and eastern coasts, these wintry over high ground and possibly to low levels in the far northeast. A brisk northerly wind will accentuate the cold feel. Overnight frost will be widespread, especially in the north. Towards the middle of next week, an area of rain and stronger winds may move southeast across much of the UK, bringing a brief less cold spell, before a resumption of the cold northerly airflow with further wintry showers. Although very uncertain, high pressure may then settle things down by next weekend before it possibly turns milder, wetter and windier from the west late in the period.
