Overcast weather
Overcast is a weather type.
Initial daily weather rolls
| Climate group | Winter | Spring | Summer | Autumn |
|---|---|---|---|---|
| Desert | 0% | 0% | 0% | 0% |
| Mountain and Mountain Woods | 25% | 15% | 15% | 20% |
| Rainforest | 25% | 10% | 10% | 20% |
| Swamp and Ocean climate | 25% | 20% | 15% | 15% |
| Subtropical | 20% | 10% | 10% | 15% |
| Woodlands and Haunted Woodlands | 20% | 10% | 5% | 20% |
These are classic initial daily weather-type chances for each climate group. Mountain Woods uses the Mountains row; Haunted Woodlands uses Woodlands. Ocean uses the Swamp row.
Without moving weather systems, each climate zone also has a 12% chance to change weather each hour. With Weather as places, as used online, moving regional systems determine the weather at your location. The moving system adjusts rain and thunder coverage; the initial roll percentages are not local precipitation probabilities.
Rain, sleet and snow at your location depend on air temperature, height and hour; these initial roll chances do not fix the local precipitation. See Weather for the temperature thresholds and forecast.
