Michael Lumb struck a century against his old county as Yorkshire experienced a frustrating opening day in their LV=County Championship Division One match against Nottinghamshire at Scarborough.
Although much of the country was bathed in morning sunshine, an infuriating fine drizzle and damp outfield delayed the start until 1:10pm.
Yorkshire may have been hoping for an earlier start in more helpful conditions when they won the toss and inserted their opponents, but Lumb and Australian Ed Cowan settled after Alex Hales fell cheaply.
They added 101 for the second wicket and, at the close, Lumb was unbeaten on 116 with Nottinghamshire comfortably placed on 177 for two.
Yorkshire made one change to the side which drew with Somerset at Taunton last week, out-of-form opener Joe Sayers being replaced by Alex Lees.
Paceman Iain Wardlaw, who had also been in the squad, was released to join the Scotland party for their four-day match against Australia A at The Grange, starting on Friday.
When play was finally able to begin, Yorkshire struck with the fifth ball of the match as Hales drove too casually at Ryan Sidebottom and was caught behind by Andrew Hodd.
Steven Patterson looked the more dangerous of the new-ball pairing, but he and Sidebottom were denied a further breakthrough by Cowan and Lumb.
It took Cowan seven overs to get off the mark by clipping Sidebottom through square-leg, with progress steady as Notts reached 72 for one at tea.
Lumb moved up a gear at the start of the long evening session, forcing Patterson off the back foot for four and on-driving Moin Ashraf to the fence to reach his fifth championship half-century in 12 knocks against Yorkshire since leaving the county at the end of the 2006 season.
The stand moved into three figures but, shortly afterwards, Patterson claimed a deserved breakthrough, Cowan pushing hard and sending a catch straight into the hands of Gary Ballance at first slip for 47.
Lumb responded to Adil Rashid’s introduction with four and three off consecutive balls to overtake his previous best score of 81 against Yorkshire.
It was the leg-spinner Lumb moved to three figures off, too, as he drove regally through cover to reach the landmark off 183 deliveries, including 13 fours.
With Yorkshire behind the over-rate, Adam Lyth joined the attack with his off-spin but the light deteriorated and, when Sidebottom turned to pace again, the umpires decided it was too dark to continue.
There was a brief resumption, only for the gloom to return with Lumb 116 not out and James Taylor 12.
