The USDA Plant Hardiness Zone Map puts Arley in Zone 8a (10 to 15°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.

Why 03/30 isn't a guarantee
03/30 is the middle of 30 years of NOAA records, not a promise. Plant by 03/10 and you're betting against frost in roughly 9 years out of 10. 04/16 is the safer bet, historically only a 1-in-10 chance of frost that late.
