Newtonia, MO: when does the frost end?
Around 04/09 is the usual last spring frost, about 224 days away. Fall's first freeze usually shows up around 10/26, roughly 199 days after the last spring frost.

Stretching the season past the first frost
With roughly 8 weeks until Newtonia's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
How much risk comes with planting early here
04/09 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/24 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/27 and only about 1 year in 10 sees frost after that.
