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 20 | Apr 6 | Apr 21 | Oct 22 | Nov 1 | Nov 16 | 192 / 211 / 233 |
| 32°F (freeze) | Mar 2 | Mar 25 | Apr 10 | Oct 31 | Nov 12 | Dec 2 | 211 / 235 / 263 |
