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 5 | Mar 24 | Apr 13 | Oct 27 | Nov 9 | Nov 24 | 204 / 229 / 256 |
| 32°F (freeze) | Feb 17 | Mar 11 | Mar 30 | Nov 5 | Nov 20 | Dec 12 | 230 / 256 / 287 |
