The 30-year-old was recently charged with drink driving and dangerous driving but the terms of his £50,000 bail allow him to play gigs.
On Sunday dark rockers Nick Cave and The Bad Seeds will play before reformed Britpop stars Blur close the festival.
Weatherwoman Laura Gilchrist said: "The risk will be there (this morning) as well, but it looks like improving tomorrow, as that risk moves northward.
"There's a risk of isolated showers at any point but that risk is very very much less. Suncream won't be wasted."
Temperatures could reach 23 degrees centigrade, she added.
In 2005, storms and flash flooding caused havoc at the site, with many festival-goers having to use their tents as makeshift boats to float around waterlogged areas.
In 2007, more rain ensured a similar mudbath, though a new draining system meant a repeat of 2005 was avoided.
The mixed weather was offset by encouraging figures on crime at the event, for which all 137,000 tickets have been sold.
Avon and Somerset police said 54 people were arrested in the first 36 hours of the festival - an improved strike rate on last year.
Most of the arrests were for drug possession and a handful for theft.
The rate of tent thefts in particular has already "decreased significantly", officers said. This time last year 115 had been reported compared to just 48 today.
Earlier in the day police stopped and searched a van on route onto the Glastonbury Site. Seven people were discovered in the back of the vehicle and two arrested for drugs offences.
Sgt Kerry Williams said: "In the last 36 hours we have arrested more people than in previous years and this proves to be a great result. Working in conjunction with festival security we have managed to detect more crime."
The force said its Neighbourhood Watch scheme, operating at the event for the first time, was helping to keep people safe.
The project aims to encourage festival goers in neighbouring tents to befriend and look out for each other. Crime prevention texts are also being sent to registered users.
Last year's festival saw 751 offences reported, of which 177 were drug related. There were 199 arrests.
