Snow amount was at least 0.5 inches, but that would only be a rough estimate since I was at work, and the precip changed to rain by 11AM with some melting by the time I returned. Might as well not report an estimated snow amount since many from neighboring stations would likely have had the day off and hence a better snow measurement.
