WOAY-TV (Oak Hill, WV): The cold weather this weekend will prompt a landscape of white Sunday morning.
Chief Meteorologist Chad Merrill has the latest:
Frost can occur with air temperatures as warm as 35 degrees if you have the right conditions. Scattered frost will occur with air temperatures of 32 to 35 degrees and a widespread blanket of frost if the temperatures is below 32 degrees.
One of the critical pieces of the puzzle is a wet topsoil. You need the water in order to form that lattice structure, which is called frost. We’ve had a surplus of topsoil moisture so far this winter and the ground remains moist heading into the weekend.
So Sunday morning, when the temperature drops to 20 degrees, that lattice structure can form with the heavy do on the grass. You will wake up to a blanket of white Sunday morning before we saw the record highs by the middle part of the week.
