They will try for a last minute "false flag" to bait the US to think that Iran broke the ceasefire first as always.
To Downvoters: You do understand that it was Israel that attacked first right? They are not happy with this provisional ceasefire agreement.
The Israelis are playing this like a strategy game and using ancient tactics. Therefore, I predict they will try to get all US military-aged men into Iran before they nuke it. Then, they will unleash all of the drones they have hidden all across the US.
