Thunder weather

Thunder is a weather type.

Initial daily weather rolls

Climate group	Winter	Spring	Summer	Autumn
Desert	2%	5%	0%	2%
Mountain and Mountain Woods	0%	10%	5%	10%
Rainforest	12%	15%	10%	15%
Swamp and Ocean climate	0%	15%	10%	15%
Subtropical	10%	15%	15%	15%
Woodlands and Haunted Woodlands	0%	10%	5%	10%

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.
