is going to be best. but high pressure is no longer with us by wednesday. but we're still in that cold air stream with the northerly wind bringing the odd shower down some of those north sea coast where it will feel particularly cold. we may well see a touch of frost here and there if the cloud breaks, but the cloud will tend to build up through the day on wednesday, and that could lead to a few showers, mainly for england and wales, looking a bit sunnier, perhaps for western scotland and northern ireland, but temperatures are 11 degrees in belfast and that's going to be a typical best number on wednesday. it is going to be a chilly week ahead. temperatures dropping across northern areas and there's even the risk of frost overnight before lower pressure, maybe bring some rain by the end of the week.
