On average, the first frost in parts of the New River Valley doesn’t happen for another 2 to 3 weeks.

How does this happen?

When the air is dry and the wind is calm, the last piece of the puzzle is a clear sky. A clear sky is like a bed without blankets. Those three things combined allow whatever warmth we get during the day to escape back to space.

Lynchburg’s record low Tuesday is 41 degrees set back in 1962. That could be in jeopardy.
