Ok great !! You need 20% of your average depth in rain to get the CYA to 80. It would be a little over a foot in an average inground pool. It won't be terrible to manage it with a higher CYA level for 2 months (?), or less if its a wet spring.
Or you could speed it along with a partial drain/refill if water is cheap and you have a good drainage option. See these methods :
