Steam fog from Lake Michigan rose over the Chicago shoreline on January 30 as record low temperatures were detected at O’Hare Airport. The cold spell, attributed to a polar vortex, prompted authorities to effect a wind-chill warning for the Chicago area until noon on January 31. The steam fog coming off the lake is a phenomenon that can occur at low temperatures, when the temperature of the air is lower than that of the water or ice below. Credit: Susana Leyva via Storyful
