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 8 | Apr 22 | May 10 | Oct 6 | Oct 20 | Nov 1 | 159 / 180 / 200 |
| 32°F (freeze) | Mar 25 | Apr 11 | Apr 28 | Oct 15 | Oct 29 | Nov 11 | 180 / 201 / 221 |
