I think it's like the difference between rain and heavy rain, more falls down and the sky gets darker. I found this article talking about the weather in the game:
Read this Animal Crossing: New Horizons Switch (ACNH) guide on differences when the season, weather, & time of day change. Includes weather forecast, real life weather, & patterns.
You'll see a lot more snow falling and darker clouds during heavy snow. If you've befriended Sable, you can talk to her and if she mentions a "Great Blizzard", you have heavy snow at that moment.

Good to know that, next time I will definitely talk to her , now it changes to cloudy again. I love to hear that how everyone had experience differently. Thanks
