Control weather

Control weather is a transmutation spell that changes weather in the local area.

Effect
Over a twenty minute period, control weather causes the weather in a local area to change, depending on the time of year.
 * Spring: Tornado, thunderstorm, sleet storm, or hot weather
 * Summer: Torrential rain, heat wave, or hailstorm
 * Autumn: Hot or cold weather, fog, or sleet
 * Winter: Frigid cold, blizzard, or thaw
 * Late winter or early spring (coastal area): Hurricane-force winds

The spellcaster controls the general tendencies of the weather, such as the direction and intensity of the wind. He cannot control specific applications of the weather (where lightning strikes, for example) or the exact path of a tornado. The weather continues as the caster left it for the duration, or until he designates a new kind of weather (which fully manifests itself ten minutes later). Contradictory conditions are not possible simultaneously - fog and strong wind, for example.

Control weather can do away with atmospheric phenomena (naturally occurring or otherwise) as well as create them.

Druids casting this spell double the duration and affect a circle with a three-mile radius.
