“ That is the first time I have ever encountered the word “graupel.” I have a feeling that it will not be the last.”
It’s the new hip word for sleet.
It is definitely NOT sleet. It is NOT hail. It’s kind of a soft spherical pellet (like hail, but soft) and it causes huge avalanche danger in the mountains. It is not a hip, new word — it’s been around at least 130 years. See my post above.
