Lollapalooza got wet and muddy -- again.
The festival’s infamously rainy history continued this year as rain moved through the Chicago area Friday afternoon and briefly soaked Grant Park.
The National Weather Service even warned of hail, gusty winds and occasional cloud-to-ground lightning affecting the lakefront, from Lakeview to Northerly Island.
The rain doesn't end there. There's a chance for isolated showers and storms again on Saturday. The wet weather is expected to fall in 20-40 percent of the area during the afternoon and evening hours.
After a cool start to the week, the city will see temps in the low-80s for the first day of the festival.
Sunday looks to be the better day in terms of weather for the festival with temps in the low- to mid-80s and mostly sunny skies.
Fans drudged through soggy grounds during the opening day of the festival last year and thousands were evacuated from the area in 2012 after storms rolled through Chicago.
Fans also danced their way through muddy grounds and standing water after storms during the festival in 2011, causing “one of the worst aftermaths” Grant Park has seen.
This year’s festival kicks off Friday in Chicago’s Grant Park and will feature weekend performances by headliners like Eminem, Skrillex, Kings of Leon and Arctic Monkeys.
Last year, city officials and festival organizers reported a crowd of 100,000 people attended the weekend festivities each day, setting a new record for the event.
