The USDA Plant Hardiness Zone Map puts Falls City in Zone 9a (20 to 25°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
Zone 9a around Falls City has about 15 weeks left before the first fall frost — that's the usual window to get a cold frame up if you want to keep harvesting past it.
Why 02/16 isn't a guarantee
02/16 is the middle of 30 years of NOAA records, not a promise. Plant by 01/13 and you're betting against frost in roughly 9 years out of 10. 03/13 is the safer bet, historically only a 1-in-10 chance of frost that late.
