Staying mixed and cool with rain, sleet and snow at times
Cool days in the coming week, although there will be occasions when milder air intrudes from the Atlantic. The jet stream is to the south of the UK and Ireland overall and this allows from the cooler air to affect most places. There will be rain, sleet and snow at times. Indications are that temperatures fall again through later part of the weekend and early next week.
