Showers will muddy the fields in Somerset for Glastonbury this weekend, but none of the five days are forecast to be a total washout.
Thursday will be dry with periods of clouds and sunshine. The day will be mild, overall, with temperatures near 21 C.
Those planning to camp out for the week should pack some warm clothes as lows will bottom out around 10-12 C.
Though conditions will remain dry for campers pitching tents through Thursday, festivalgoers won't want to be without a waterproof shelter come Friday.
A front will move in to start the weekend, bringing the threat of showers throughout the day Friday.
Those planning to see headlining act Florence + the Machine, filling in for the Foo Fighters' last-minute cancellation, will want to wear their wellies; muddy fields are likely.
"The good news is, it's not a particularly strong front. It's still going to bring some rainfall, but it won't be constant," Leister said.
Saturday will be the driest day of the weekend, but it won't be rain-free.
"Saturday will be an improvement from Friday," Leister said. "Eighty to 90 percent of the day will be dry, but there could still be a shower or two."
Another front will arrive Sunday, threatening to unleash showers throughout the day, as The Who prepares to take the stage. Temperatures will climb near 19 C.
"Despite the chances for rain, it won't be a washout," Leister said. "None of the days will be miserable, even for campers."
According to SkyNews, only eight festivals have been rain-free since Glastonbury began in 1970.
