The drawing for the next Powerball is estimated to be just shy of $150 million. No one won the drawing on Saturday and now the rollover brings the jackpot to $145 million. The winning numbers were 15, 21, 23, 28, 36 and a Powerball of 20. The last time a winning Powerball ticket was sold was when the jackpot reached $258 million. The next drawing will take place on Wednesday.
