The Powerball jackpot has grown to $643 million -- with a cash payout of $290.6 million -- after no one won Monday night's drawing. A total that was already the highest of the year has now crept higher. The next drawing will take place Wednesday night.

No one hit the jackpot in the Monday, Aug. 18 drawing, so the grand prize will increase to an estimated $643 million.

The current Powerball jackpot is now the biggest lottery prize of the year so far, eclipsing the $526.5 million Powerball prize won by a California resident in March.
