Weather prediction

From Ardrana

By casting weather prediction, the priest can predict the weather conditions at his location for a period of days or even weeks. The caster becomes aware of the prevailing conditions, trends, and weather systems that may affect his present location. Temperature, wind speed and direction, cloud cover, and precipitation can all be predicted with great accuracy for the next day, with diminishing accuracy for each day after that. Magical or supernatural phenomena cannot be predicted.

Priests of powers concerned with weather may use this spell to determine the best time for certain ceremonies or observances. Other priests find weather prediction useful for planning journeys or selecting campsites.

Note: Weather prediction originally appeared in this form in the Player's Option: Spells and Magic supplement for the AD&D game from TSR. Its use here is for the purposes of providing context for the campaign only.
