Motorists will need to be prepared for the possibility of some slick roads across parts of Iowa this week. Warmer air combined with the cold snow cover has produced areas of dense fog. National Weather Service Meteorologist Frank Boksa says that fog can present more dangers than just reduced visibility.
“It can deposit a very thin layer of moisture on some surfaces and if lesser traveled roads aren’t untreated, you can get a little glazing of ice on the road,” Boksa said. A potentially dangerous weather system is expected to move into the state late Tuesday night into Wednesday.
Boksa says the system will include more warm air, setting up the chance for freezing rain. The forecast for Thursday includes a chance of freezing rain statewide, with light snow possible across northern Iowa. High temperatures throughout the week will range from the mid 20s to mid 30s, with overnight lows in the teens and 20s.
