If the heavens rain out
The Festival of Stars,
Washed out too will be our hearts

Meet not heart
Rain middle/during sky/heavens
雨で逢わぬ (ame de awa-nu) means a date is rained out. 有頂天 (uchouten) means full of ecstasy. This plays with the order, creating a new word, to say that if the Star Festival is rained out, people’s hearts will be sad.
