Yorkshire head into today's final day at Scarborough needing seven Leicestershire wickets to clinch their first County Championship win of 2012.
On the day when Colin Graves announced that he would be stepping into the role of executive chairman at the club, an amalgamation of his current role as chairman and the vacant post of chief
executive, Yorkshire's players were largely held up by the weather.
Rain forced a break between 11.15am and 3.30pm, which enabled the visitors to delay likely defeat.
Having resumed day three on 3-1 as they followed on in their second innings, Leicester slipped to 8-2 when Jacques Du Toit was caught at cover by Joe Sayers as he got a leading edge to Steve
Ramnaresh Sarwan fell lbw to Patterson when play resumed in the afternoon as the visitors were reduced to 14-3, but opener Matt Boyce and Josh Cobb fashioned a recovery.
They shared an unbroken 88 for the fourth wicket inside 31 overs to reduce the deficit to 229 runs.
Yorkshire are still expected to wrap up the win, but will need a far more settled day weather wise today.
Rain, bad light and even sleet halted play. And when play was possible, it was biting cold and more suitable for sports such as skiing and snowboarding rather than cricket.
In truth, Yorkshire rarely look like taking a wicket following Patterson's third.
The ball stopped swinging for the quicks, and Anthony McGrath's medium pace and Adil Rashid's leg-spin looked most threatening.
Boyce and Cobb, who will resume on 46 and 45 respectively, were brought out of their comfort zone by one of Rashid's most probing spells of the season so far. He may have gone for 18 runs in his
four overs, but the batsmen scored the majority of those runs either square or behind the wicket.
Graves, who sold his shares in supermarket chain Costcutter last November, will take on a more hands-on role at Yorkshire on Monday.
He joined the Yorkshire board in 2002, and will be paid a salary for the first time in 12 years, although "it won't break the bank".
"I want to drive the business behind Yorkshire," he said. "We've a lot to do. I want to improve everything we've got at the ground, but we've got the basic infrastructure in place.
"I will do it for as long as the board want me to. It was their suggestion when they knew I was packing in Costcutter."
Yorkshire begin their Clydesdale Bank 40 campaign against Kent at Headingley tomorrow, starting at 1.45pm. There are three seven-team groups in the competition, and Yorkshire will have to finish
top of their group to guarantee a place in September's semi-finals for the second time in three years. Derbyshire, Northants, Sussex, the Unicorns and Warwickshire are the other teams in
