BRIDGEPORT. W. Va. (WDTV)- Cooler temperatures allow for the possibility of frost to form on your garden or car. A few things have to happen before a frost can from.
How warm was it during the day?
If the temperature reached 75ºF
Is it windy?
A still night allows cold air to pool near the ground so a heavy, cold wind sweeps away warm air near the ground.
Is it cloudy?
The clouds will slow radiational cooling and help keep the frost away.
We all so some different freezes and frost. The two are a light frost and a hard freeze.
A light frost occurs when the nighttime temperature drops to below 32 degrees Fahrenheit.
A hard freeze is a period of at least four consecutive hours of air temperatures that are below 25 degrees Fahrenheit. Many plants can survive a brief frost, but very few can survive a hard freeze.
