Rain is a great aerator. If I need to lower my Alk, I always like to do it ahead of a rain forecast.
Whether or not you need to lower you alk depends on if the PH is increasing rapidly for you or not. If it isn't, then probably not. If it is, the lower you can get your alk within range, the slower the PH rise will tend to be.
