Dig out the brolly...

Weather forecasters are predicting some heavy rain for this weekend's instalment of Glastonbury.

Well it's now mid-summer. Today (June 21st) is the summer solstice, a day steeped in tradition and mythology. Druids are making their way to Stonehenge, in order to celebrate ancient Celtic religion.

Perhaps they should do a sun dance. Weather forecasters are continuing to feed data to fans, allowing festival goers to second guess the conditions at this summer's Glastonbury.

The Met Office have been warning of mixed conditions, with periods of sunshine interrupted by rain. Now forecasters are claiming that "heavy showers" could push their way into the Worthy Farm site.

Speaking to Gigwise, a spokesperson for the Met Office explained that Glastonbury will suffer from mixed conditions. ''As people arrive on Wednesday there will be a mix of sunshine and showers through the morning. Thursday is looking mainly dry but cloudy with sunny spells, though there is the chance of a shower. It will be quite breezy at times which will make it feel quite cool."

Continuing, the spokesperson explained that the weekend will continue with some heavy rain. ''Much the same on Friday with a mix of sunshine and light rain at times, again feeling cool in the wind. Over the weekend unfortunately it the weather will take a turn for the worse. So although the next few days are looking mainly dry with light showers Saturday and Sunday will see heavy showers.''

The Glastonbury site opens today, with members of the ClashMusic set to be on site by this evening. The line up is - as ever - deeply eclectic, with Worthy Farm preparing itself for appearances from U2, Coldplay, Beyonce, Morrissey, Queens Of The Stone Age and Tinie Tempah.

Glastonbury runs between June 24th - 26th.
