An Invocation to Taranis that can be used during a drought
"We call upon you tonight, Great Thunderer. Taranis, we ask that you bring the rains to make our crops grow. We have been in a time of drought and our crops are calling for water! Taranis, we call to you to come in your great-wheeled chariot that goes across the skies. We ask that you bring your great hammer that makes the thunder. And most of all, we ask that you bring the rains that we need."
