When can you plant in Heber, UT?
Around 06/04 is the usual last spring frost, about 280 days away. The first fall frost typically arrives around 09/20, about 106 frost-free days later.
The USDA Plant Hardiness Zone Map puts Heber in Zone 6a (-10 to -5°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.

How much risk comes with planting early here
06/04 is the middle of 30 years of NOAA records, not a promise. Plant by 05/18 and you're betting against frost in roughly 9 years out of 10. 06/21 is the safer bet, historically only a 1-in-10 chance of frost that late.
