Revellers heading to T in the Park at its new Perthshire home have been urged to pack for whatever the weather with early forecasts suggesting a changeable weekend ahead.
Festival goers have been told to expect dry and sunny weather on Thursday when the campsite opens.
But rain could well hit the site at Strathallan Castle on Friday morning before hopefully clearing ahead of the first bands taking to the stage later that day.
The Met Office reckons Saturday will be a mixture of sunshine and showers, before more of the same is predicted for the festival’s final day on Sunday.
More than 70,000 people are expected to attend each day and they will be hoping to keep the use of waterproof ponchos to a minimum throughout the three-day event.
The news comes as it emerged that warmer conditions are due to return to the UK later this week after a dip over the coming days.
The temperature dial has been turned down for a few more days yet as forecasters predict that the warm, dry weather will continue in the south and south east, broken up by some patchy showers.
But heavy rain and storms are likely in much of the north and west of England, as well as Wales and Scotland until around tomorrow when the outlook brightens again.
John Griffiths, a forecaster for MeteoGroup, said: “If you drew a line between Lincolnshire and Bristol then everything below that line is going to be nice and dry and over that line it will get wetter and wetter the further north you go.”
The mercury this week is unlikely to hit the dizzying highs of last week’s record-breaking temperatures of 36.7C (98.1F), recorded at Heathrow, while many other areas of the UK broke the 30C (86F) mark.
But forecasters have said it will remain warm despite the wet weather, with temperatures of 22C in the south east and London and a balmy 20C in Scotland yesterday.
A large band of rain is to sweep northwest across the country before being replaced by warmer weather by Thursday and Friday.
There will be highs of 26C in London and bright spells everywhere else.
Forecasters hope temperatures at T in the Park could reach as high as 20C, although there is still some uncertainty over that at this stage.
Mr Griffiths added: “There is quite a big split over the country. In the south east and south coast there will be some patchy rain but some good sunny spells and it will be mainly dry.
“There is a big band of showery rain pushing north west from Ireland during the day today and covering northern parts of Cornwall and Wales. It should reach Scotland by the afternoon.”
Lightning could strike parts of Scotland again today, he added, following the widespread thunderstorms over the weekend.
It comes after two people died as a result of separate lightning strikes in the Brecon Beacons on Sunday.
A further two people remain in hospital following the lightning storm at around midday on the Pen Y Fan mountain range in Powys, mid-Wales, a spokesperson at the Prince Charles Hospital in Merthyr Tydfil said.
