Thu 6 Feb Wales

It is likely to be rather more settled across the UK in this period, especially at first. High pressure will sit close to, or over the UK, and will most likely drift away slowly eastwards with time. Consequently, southern and eastern areas are likely to see the driest conditions, with lightest winds, which could lead to overnight frost and fog with temperatures a little below normal. Further north and west, there is a risk of incursions of Atlantic air and fontal systems at times, which would bring some rain here, but with milder temperatures. There is a very low chance that if the high orientates in such a way that a more easterly (rather than southerly/southeasterly) flow develops, a spell of much colder conditions could develop across the UK.
