Outlook for the UK over the next 6-30 days

UK Outlook for Sunday 27 May 2018 to Tuesday 5 Jun 2018:

The Bank Holiday weekend will be mostly fine and sunny, after any early mist and fog has cleared. Scattered thunderstorms could affect southern and central areas at times however, with mist and low cloud possibly affecting the east coast. It will very warm or hot in the south and west, but often much cooler near eastern coasts. There will also be a brisk easterly wind across southern areas. Similar conditions will prevail into next week, but some longer spells of heavy, thundery rain may move northwards into central parts. Into the beginning of June confidence is low, but it will most likely remain overall drier and warmer than average. However there will be an increasing chance of more unsettled, cooler conditions developing.

UK Outlook for Wednesday 6 Jun 2018 to Wednesday 20 Jun 2018:

For the beginning of June there is low confidence in the type of weather pattern expected across the UK. Conditions are likely to become generally more unsettled as we head towards the middle of the month, with periods of rain or showers being more frequent and widespread. There will still be some more settled spells at times, these most likely in the south and southeast. Temperatures will probably be near or slightly above normal, but there is continued potential for further very warm spells.
