Some trees had thick scaly bark, and falling snow accumulated in the crevices around them. Trees with smoother bark had hardly any. But, given the wind, some had stuck to the tree trunks anyway.
Winter weeds, on the other hand, ended up with Snow Hats!
Next Time it Snows: take a walk around your neighborhood and notice where the snow ends up on trees and plants.
Further observation: does where and how snow sticks to trees and winter weeds vary with the water content of the snow? Powdery snow forms in cold, dry air so it doesn't have much moisture. Flakes that form when the temperature is near freezing will have more moisture. That makes them stickier - great for making snowballs - but also heavier.
