Freeze probability table
| Threshold | Last spring occurrence | First fall occurrence | Season length (days) 90% / 50% / 10% | ||||
|---|---|---|---|---|---|---|---|
| Early (90% chance of a later freeze) | Median (50%) | Cautious (10% chance of a later freeze) | Early (10% chance by then) | Median (50%) | Late (90% chance by then) | ||
| 36°F (light frost possible) | Apr 16 | May 1 | May 15 | Oct 6 | Oct 17 | Oct 29 | 151 / 169 / 188 |
| 32°F (freeze) | Apr 2 | Apr 18 | May 4 | Oct 13 | Oct 25 | Nov 7 | 170 / 191 / 214 |
