Here is my weekly weather quiz question for the last time. What is “Frazil Ice?” Here is the correct answer. Frazil Ice: In hydrologic terms, fine spicules, plates, or discoids of ice suspended in water. In rivers and lakes, frazil is formed in supercooled, turbulent water. I’ll have a new weekly weather quiz question for you on Monday. The first person to post the correct answer as a comment on this page will win a week of free personalized weather forecasts tailored to your needs. Good luck.
