|---|---|
| 90% (early: most years still freeze after this) | May 5 |
| 50% (the "average" last frost) | May 19 |
| 10% (cautious: only 1 year in 10 freezes later) | Jun 1 |

| 50% (the "average" first frost) | Sep 24 |
| 90% (late: most years have frozen by now) | Oct 5 |
Light frost, freeze and hard freeze
| Threshold | Last spring (50%) | First fall (50%) |
|---|---|---|
