It is extremely unlikely to see snow in Osaka during the month of November. Historically, November in Osaka is characterized by mild, pleasant autumn weather with average daytime highs around 16°C (61°F) and evening lows near 7°C (45°F). While the city does experience some rainfall, the temperatures remain well above freezing, preventing any snowfall. If you are looking for snow in Japan during November, you would typically need to travel much further north to the Hokkaido region or into the high-altitude Japanese Alps. For Osaka visitors, November is actually one of the most popular months to visit not for snow, but for the stunning autumn foliage (koyo), which usually peaks in the latter half of the month. You should pack layers, such as a light jacket or sweater, as the air becomes crisp and breezy, but you can safely leave your heavy snow gear at home for an Osaka-centric trip during this time.
