Becoming dry tonight, with warm sunshine tomorrow.
This Evening and Tonight:
There could be some thundery showers in the east this evening, but it will soon become dry and clear. With light winds we could see some patchy mist and fog develop during the early hours. Minimum Temperature 10C.
Plenty of warm sunshine will develop after any early mist and fog clears. However isolated thundery showers are possible for the afternoon, with the risk of hail. Maximum Temperature 23C.
Outlook for Wednesday to Friday:
It will stay generally warm, after some early mist clears. Wednesday will be mostly dry and sunny, however the risk of thunderstorms increases later this week.
Day 6 to 15
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 be warm or very warm 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.
Day 16 to 30
For the beginning of June there is very 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.
