Not sure which station your referring to but the same thing happened with The Big DM 101.3 2 weeks ago on Saturday. They were loud and clear on 100.7, 100.9, and 101.7. It has to be a technical glitch if nothing else. I noticed WFMV Gospel 95.3 hasn't been the same since Tuesday's severe storms. Their signal is weaker and quieter, with some bleed on 95.9. So, weather could have a lot to do with it also.
