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 24 | Apr 8 | Apr 26 | Oct 14 | Oct 26 | Nov 8 | 178 / 200 / 220 |
| 32°F (freeze) | Mar 7 | Mar 28 | Apr 12 | Oct 23 | Nov 5 | Nov 22 | 202 / 222 / 248 |
