Undated  (KROC AM News)  - You may have missed it over the weekend - there were no grand prize winners in either the Mega Millions or Powerball lottery drawings.

The Mega Millions grand prize has grown to $390 million and will be up for grabs Tuesday night.

The Powerball jackpot now stands at $222 million. That game’s next drawing will be Wednesday evening.
