Today’s weather forecast for Minnesota: Highs in the 70s, scattered showers and storms in the west... and if you live anywhere near a cottonwood tree, a good chance for “snow.”

It’s an annual late spring-early summer tradition: Cottonwood trees release thousands upon thousands of tiny seeds attached to strands of “cotton” that help those seeds drift through the air like fluffy snowflakes.

The cotton is what gave the trees their name — and depending on what you think of those seeds, it’s also what gives those trees a bad name.

The floating cotton certainly doesn’t help anyone suffering from allergies. It can clog up air vents and air conditioning units. At dusk, it can make the world resemble “The Upside Down” from “Stranger Things.” And as the Star Tribune reported, it might have even confused a certain former NBA star while in town for the playoffs.

At the same time, when those floating seeds are drifting about on a sunny day, silhouetted against the blue sky — it can be a magical, beautiful scene.
