There is a potential for frost in parts of Iowa tonight. National Weather Service meteorologist Alex Vorst says areas with clear skies could see frost.
“The best locations for potentially seeing frost is going to be north, northern, northeastern Iowa where cloud cover looks to be largely minimized as we have this frontal boundary passing tonight,” Vorst says. He says frost is less likely under cloudy skies. “With the incoming boundary and the cloud cover, that will actually help insulate the surface a little bit, and areas where there are clear skies will be able to drop a little bit further temperature wise, be able to cool off temperature wise, and that’s where the frost will be possible,” he says. if you’re in northern Iowa, kind of northeastern Iowa, that’s where you better frost chances will exist.”
Vorst says the wind shift will give us warmer temperatures. “Clear skies, but also low level wind flow will help to bring some of those warmer temperatures,” he says. “Because will go from kind of north-northwesterly winds, which are typically cold, to west southwest winds, which are typically warmer.”…
