The last spring frost here typically falls around 06/01, about 277 days from today. The first fall frost typically arrives around 09/23, about 115 frost-free days later.
The USDA Plant Hardiness Zone Map puts South Range in Zone 5a (-20 to -15°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.
What to do before the first frost
About 4 weeks of growing season left in South Range before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.
Why 06/01 isn't a guarantee
06/01 is the middle of 30 years of NOAA records, not a promise. Plant by 05/14 and you're betting against frost in roughly 9 years out of 10. 06/17 is the safer bet, historically only a 1-in-10 chance of frost that late.
