Wright, WY: when does the frost end?

Zone 5a

Around 05/25 is the usual last spring frost, about 270 days away. Fall's first freeze usually shows up around 09/23, roughly 120 days after the last spring frost.

The USDA Plant Hardiness Zone Map puts Wright in Zone 5a (-20 to -15°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.

Stretching the season past the first frost

With roughly 4 weeks until Wright'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

05/25 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 05/14 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 06/08 and only about 1 year in 10 sees frost after that.
