It was quite cold this spring. After several years of very little snow, we had several inches for most of the winter and that took its time melting. Then we still had nights below freezing and cold days for quite a while. Still there were signs. The daffodils started blooming on schedule. There were buds here and there. And when we got a few warm days towards the end of the month it was catch up time.
Noticing an icy flower on the car’s roof when I looked out the front door on a chilly morning, I ran for my camera. The last time I saw such large ice crystals on that car was in late November, 2019. Fall and now spring – still, the conditions must have been just right for that to happen.
When the temperature is below 0°C (32°F) and supersaturated humid air flows over a textured surface, ice can be deposited directly without first going through a liquid phase. And as you can see, the results can be quite spectacular.
