BBC monthly outlook
Monday 30 May—Sunday 5 June
Dry start. Rain for England and Wales midweek.
Bank holiday Monday will see another dry day for many places. Northwest Scotland and Northern Ireland will see a few heavy showers developing, and many eastern counties will be cloudy in the morning. Otherwise there will be plenty of fine, rather warm weather, but eastern coasts will be cool and breezy. For Tuesday and Wednesday, much of England and Wales will be cloudy with outbreaks of rain - some of these heavy and possibly thundery. Scotland and Northern Ireland will be mostly dry with some sunshine, the best of the sunshine over western Scotland. Later in the week, the drier weather will extend southwards with sunny spells in most places, while the northerly breeze will keep eastern coastal areas cooler and sometimes more cloudy. Southeast England keeps the threat of a few showers, even into the weekend, while most of the country should see the dry weather continue, always with the best of the sunshine, and highest temperatures, in the west.
Monday 6 June—Sunday 12 June
More fine weather, especially in the northwest
The mainly fine weather will continue into the second week of June, with many parts of the country dry and warm with sunny spells, and it may become very warm for a time. East coastal parts may remain cooler with some cloudier periods and there's always the chance of a few showers extending from the continent into the south and southwest of England. Its uncertain whether this fine weather will last all week; later in the week the high pressure may weaken and allow more unsettled conditions to move in from the west.
Monday 13 June—Sunday 26 June
Mixed weather most likely
At the moment, there is no strong signal from the computer forecasts of any particular weather pattern prevailing later in June. Winds are more likely to come from the west or southwest, for at least one spell of a few days. This would bring some rain and showers at times, with the rain more likely in the southwest and west, where it may be heavy. Eastern parts will see the best of the drier periods, with temperatures on the warm side at times.
Next week
Further into June, will the northwest keep the best weather?
