Well hopefully I'm good luck for Knoxville- I remember that March 2022 snowstorm and being a bit sad thinking I might never see that kind of storm again here... and then January 2024 came around haha. I did notice that the tri-cities seemed to get the short end of the stick these past few winters despite averaging more snow than Knoxville, it's really interesting how the shape of the valley influences which storm types are better/worse for which areas, despite how geographically close TRI/TYS/CHA all are. Blount/Sevier counties got warm nosed in January 2024, but they also get some solid accumulation during NW flow events while in West Knox I've usually seen flurries or a dusting at best from those. Chattanooga seems like a snow lovers nightmare where anything that can go wrong will go wrong, I was glad they finally got to cash in last January. I remember the post you're referencing about the natural spillway for cold air into the valley and it makes sense that it would work in favor of the Knox area.
This might be a dumb question, but do you think that there's a correlation between the very strong pacific jet stream that we've seen in recent winters and the shift in snow between the tri-cities and Knoxville? As a novice, it seems like Nor'Easters and Apps runners/Great Lake cutters are less common than I remember from the 2002-2010 period when I followed the weather more closely - but sliders that move west to east and weaker storms that ride along a frontal boundary are more common, and Knoxville has cashed in when one of them is timed correctly with a shot of cold air that briefly buckles the flow. Would the ideal storm track for TRI be something that is more south to north, so that a strengthening storm east of the valley would bring winds from the north?
