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 13 | Apr 28 | May 13 | Oct 7 | Oct 18 | Oct 30 | 153 / 174 / 191 |
| 32°F (freeze) | Mar 31 | Apr 16 | Apr 30 | Oct 13 | Oct 26 | Nov 7 | 173 / 193 / 214 |
