Frost likely Frost possible Frost unlikely Frost is likely until May 17 and fades out by June 22. It is unlikely from then until September 3, and likely again after October 5. The dashed lines are the typical dates, June 6 and September 20.

Your season is too short for a separate fall planting of cabbage, broccoli and snap beans: sown late enough to be a fall crop, it wouldn't be ready before the typical first frost. Your spring planting is your harvest.
