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 10 | Mar 29 | Apr 14 | Oct 23 | Nov 6 | Nov 22 | 201 / 223 / 247 |
| 32°F (freeze) | Feb 22 | Mar 15 | Mar 31 | Nov 3 | Nov 19 | Dec 10 | 224 / 249 / 278 |
