Can bless potentially turn a roll of 16, 17, 18, or 19 into a natural 20?

@JeremyECrawford can bless potentially turn a roll of 16, 17, 18, or 19 into a natural 20, or is the effect different than cutting words?

The bless spell adds to a roll's total. It can't make the d20 roll a 20. #DnD https://t.co/jyWXXUxcm9

@ClydeHumphreyJr @BobbyBarbarianthus the issue with the odd ruling that Cutting Words can *change the original die roll* I'll look up whatever I wrote about cutting words. If I wrote something silly, I'll emend it.
