Britain enjoyed temperatures comparable to areas of Greece as sunshine made a welcome appearance on the Bank Holiday.
But Nick Prebble, meteorologist at MeteoGroup, warned that it could be the last chance to have a barbecue for the next few days as the weather begins to deteriorate. The Bank Holiday was probably going to prove the warmest day of the week for many, he said.
A Met Office spokesman said rain overnight would be followed by a fine day with many areas enjoying bright and fairly sunny conditions.
"We have got showery outbreaks and rain across many western fringes now, it will be going into Wales, the north west of England in the next few hours and western Scotland and that will gradually work its way eastwards."
