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) | Mar 23 | Apr 8 | Apr 24 | Oct 19 | Oct 30 | Nov 10 | 184 / 204 / 225 |
| 32°F (freeze) | Mar 9 | Mar 27 | Apr 12 | Oct 27 | Nov 7 | Nov 26 | 205 / 225 / 249 |
