The forecast for the upcoming bank holiday is "uncertain" according to the Met Office.
The bank holiday is expected to be fine for southern areas, with occasional showers, and possibly wetter in the north west. Temperatures could climb to 30C or into the mid-20s depending on how the high pressure builds, the Met Office said.
Spokesman Grahame Madge said: "We've definitely switched from the hot and dry regime to something that has rain in the forecast. There's some heavy rain for the next 24 to 36 hours, providing some relief to gardeners more than helping to top up long term resources."
