Control weather

Control weather was a transmutation or alteration spell that changed the weather in the local area.

Effects
After ten minutes of casting, the weather in a two-mile (3.2 km) radius began to change toward the chosen conditions, within the limitations of the season. Older versions of this spell could affect a randomly bigger or smaller area and used the current state of precipitation, temperature, and wind as a baseline, which the caster was able to independently move up or down one level of intensity. The caster could choose the direction of the wind, but not the path of a tornado or the target of lightning. Conditions had to be compatible: you could not call for snow and a heat wave, or high winds and fog, for example.

Druids were exceptionally adept at weather control, able to affect a 50% bigger radius (or double the area  ), with twice the duration, and, for old-school druids, two levels of intensity change for each of precipitation, temperature, and wind velocity.

Components
The more recent version of this spell required only verbal and somatic components. Older versions used incense, prayer beads or other divine focus, and the priest's holy symbol.
