Review Weather-6

This snow fell when the temperature outside was 39°F. How can you get snow when the temperature is above freezing?

  1. The wind made it feel colder, allowing it to snow.

    No. While wind chill can make it feel colder, it does not actually make it colder.
  2. It was colder in the clouds where the snow formed.

    Yes. Even when air temperatures at the surface are above freezing, the clouds can be much colder. If the air at the surface is not too warm, the snow can reach the ground without melting.
  3. Rain froze into snow when it hit the ground.

    No. Freezing rain forms ice, not snow. Light, fluffy snow flakes form as they fall through the air, not after they hit the ground.
  4. This is really hail instead of snow.

    No. Hail is made of large chunks of ice, not tiny flakes.
