Powerball jackpot reaches estimated $1B ahead of tonight's drawing

UPDATE: The winning numbers for Monday are: 13, 19, 36, 39 and 59. The Powerball is: 13.
The jackpot for tonight's drawing is now at an estimated $1 billion.
The jackpot climbed to $1 billion after no one matched all six numbers Saturday night when the jackpot had been $825 million.
The jackpot remains the fifth-largest in U.S. history behind another Powerball prize and three Mega Millions jackpots.
The biggest prize was a nearly $1.6-billion Powerball jackpot won by three ticket holders in 2016.
Although the jackpot is at an estimated $1 billion, lottery officials say that's for those who receive their winnings through an annuity paid over 29 years.
Winners typically opt for cash, which for tonight's drawing would be an estimated $497.3 million.
Chances of winning Powerball are one in 292 million.
