Jan 94 is worth researching, even just old YouTube videos. Epic storm. 20-30” in SW Pa with 3-4” per hour rates at its peak. Somewhat lost to history because it was 10 months after March 93, and the official total was mysteriously low (14”) compared to other reports.
March 2018 was a nice long duration storm that kept adding on. Not super impactful though since it was March and was over probably 24 hours .
