ROANOKE, Va. – At this time last year, we were sweating. Now, we’re freezing — well, almost. Like most things in 2020, the weather has been anything but normal.
While we didn’t break any records, the frost in parts of the New River Valley and Highlands was “premature.”

On average, the first frost in parts of the New River Valley doesn’t happen for another 2 to 3 weeks.
For those seeing a little frost this morning, it's coming quite early! It's "usually" not until October for most of our area. pic.twitter.com/TYNaHp8Tlr— Chris Michaels (@WSLS_Michaels) September 20, 2020
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.
