A dense fog advisory is in effect for northern and western parts of the Chicago area this morning, but the fog is expected to clear by 9 a.m. The rest of the day will feature mostly cloudy skies and seasonable temperatures in the mid-40s, with a chance of showers returning tonight and continuing into early Thursday morning.

Why it matters

Fog can significantly reduce visibility and create hazardous driving conditions, so the advisory is an important alert for Chicago-area residents. The changing weather patterns over the next several days, including a warm surge on Friday followed by weekend storms and cooler air, are also noteworthy for the region.
