Lake-effect snow develops from narrow bands of clouds that form when cold, dry arctic air passes over a large, relatively mild lake.

The snow falling across North Texas is dry and fine, so it won't stick on the roads, but be aware of possible black ice. Unfortunately, it isn't snowman making snow. Some of the snow is called lake effect snow, which happens when cold air moves over warm water, picking up the moisture and developing into snow.

Some of the snow we saw on Wednesday morning was lake-effect snow. Moisture from area lakes met with the cold air and formed bands of snow. We saw lake-effect snow form off of Lewisville, Grapevine and Eagle Mountain Lake.

"Make sure all your outside faucets are covered. You can buy the Styrofoam covers. Everybody has seen them. You can put them on outside to make sure that helps. If you don't have that available, wrap some blankets and tape them on," Crowson said.
