The event today is probably notable enough to go here. MRX claimed it was 2 days shy of the 2nd earliest snowfall ever in Knoxville. They claimed on Facebook that Tri didn't see measurable snow Halloween 1993. I am certain that isn't true. Records show 1.3 inches for Tri on October 31st 1993. I know there was close to 3 inches here, Oneida and Tazewell. I would guess the 1.3 is probably light for Tri. I know for sure Tri got more than a trace Halloween 1993.
However, it's a rare early November day to see snow fall essentially all day long with highs that stay below 35 for most of us, and 20s for some of us. I'd say that 2+ inches of snow fell over most of the areas that got the bands, but it didn't quite manage to stick to any depth due to the nature of it. Either way, early November snow isn't common these days.
