Flavor

The priest calls upon the sky to bring a great change of weather — storm, wind, fog, or clear skies.

Mechanics

Summons a significant weather pattern (storm, gale, fog, downpour, or clear skies) appropriate to the climate/season over a wide area; the chosen weather develops over time (minutes to an hour) and persists for an extended period. Can't conjure weather impossible for the region. The exact result has some randomness. : the holy symbol.
