Really nice winters day. Low 20's Snowed in various intensities all day.
I have noticed something over the years in snowflake sizes, maybe others too? Today's flake size varied quite a bit. We would have lots of small flakes. Then a couple of large half dollar flakeswould mix in. Over the next ensuing minutes the half dollar flakes become more numerous. Soon they become the predominate flake size. As they do they become smaller and smaller. Over a time period of perhaps 30 minutes the pattern would repeat. Has anyone else noticed this in storms? Any Meteorological reason?
