This is a storm I remember well.
I was on Spring Break at WKU so I was at home in Mt. Washington at the time. I remember recording The Weather Channel coverage (still on VHS) of this event. Talk about a heavy wet snow!!!
The NWS did a great write up 0n the specifics/meteorology of this event. Click HERE to read more on the event.
So yes, big March snows are certainly not unheard of!
