The National Weather Service has issued a Freeze Warning for Wednesday morning.
The Warning, in effect from 2 am until 9 am Wednesday, covers the High Country of North Carolina and the Grayson Highlands in Virginia. The National Weather Service (NWS) says colder air will surge in on west to northwest winds late tonight, as a strong upper trough moves toward the mountains.
Temperatures will drop around or below freezing though not much frost formation is expected due to winds staying up along with scattered cloud cover, NWS adds.
A Freeze Warning means sub-freezing temperatures are imminent or highly likely. These conditions will kill any remaining garden plants or damage sensitive vegetation. If you have plants that you normally bring indoors for the winter, preparation should be made not only for tonight, but also for the remainder of the fall season and into the winter months to protect these plants.
After October 25th, the National Weather Service in Blacksburg will suspend the Frost and Freeze program for the North Carolina High Country and Grayson Highlands until the start of the 2018 growing season.
