A freezing fog advisory is in effect until 9 a.m. for a dozen counties in central and southern Kansas, including the Wichita metropolitan area.
The National Weather Service warns that visibility could drop to less than a quarter-mile, and that elevated surfaces could become slick as a result of the freezing fog.
Among the cities included in the advisory area are Russell, Lincoln, Great Bend, Ellsworth, Salina, McPherson, Newton, El Dorado and Augusta.
The fog should lift after 9 a.m., forecasters say, and then skies will clear as the temperature climbs into the low 40s. Southerly winds should stay primarily in single digits.
It will remain clear overnight as lows dip into the mid-20s, and Wednesday should see more sunshine, southerly breezes and highs topping 50. Those winds will be stronger than today, with steady breezes in the teens and gusts of more than 25 miles an hour.
