Many were surprised to find icy roadways early Wednesday morning despite temperatures sitting well above the freezing mark.
Lee Hendricks- meteorologist with the National Weather Service- said it all came down to the temperature of the ground.
“We had a long period of extremely cold temperatures (last week) so the ground temperatures were below freezing,” Hendricks said. “So even though the temperatures were warming into the mid-30s and above, the water and runoff that was still on the roads caused black ice.”
Hendricks said the travel conditions varied depending on where you were.
“It seemed to be more elevation-dependent,” he said. “If you up on the ridges and hilltops, you were OK. If you got into the valleys, temperatures were between 30-35 degrees. That was enough to catch patches of ice.”
The National Weather Service is expecting temperatures to hit 50 degrees in Butler County today- and 60 degrees on Thursday. Hendricks says he does not expect black ice to be an issue again tomorrow because the overnight temperatures will be too mild for the ground to stay frozen.
