Powerball jackpot climbs to fourth largest at $400M

Without a winning pick over the weekend, the Powerball jackpot soared to $400 million, the fourth-largest prize in history.

No one had the winning numbers -- 21, 24, 36, 42, 45 and Powerball 15 -- for Saturday's drawing. The next will be Wednesday.

This week's impressive jackpot follows just three months after the single largest prize went to an 84-year-old Florida widow, who won the $590.5 million prize.

Gloria Mackenzie chose the $278 million lump-sum payment and has reportedly purchased a $1.175 million, 6,300-square-foot homein Jacksonville, Fla., with her winnings.
