Tue 11 Nov Northern Ireland

The start of this period is likely to be largely unsettled and mostly mild, with bands or areas of rain moving across most parts of the UK, although tending to be focused more on western and possibly southern parts. Locally strong winds may also accompany some of the rain. Some drier spells are also likely, the best of these probably towards the east and possibly the north. Where skies are clear and winds light overnight, frost and fog are likely, the fog slow to clear. From around the middle of the month, we may see a transition towards more generally drier weather across the UK, and with this it is likely to turn a little cooler overall, with a greater risk of overnight frost.
