Thick fog prompts advisory for all of northern Illinois

Dense Fog Advisory:

A Dense Fog Advisory has been expanded to include the entire region with the exception of Green County, and will remain in place until 9AM. 

 

  

Visibility is expected to drop to a quarter mile or less, creating hazardous travel conditions for the morning commute. If traveling, make sure to travel at slower speeds, use low-beam headlights, and allow extra time to reach your destination. 

 

 

Overnight Rain Chances:

Once the fog lets up, mostly cloudy skies will remain for the rest of our Wednesday. A shift to a more southeasterly wind will give temperatures a slight boost, placing them near the 50° mark.  

While a few sprinkles and showers will be possible late this afternoon into the evening, a better chance arrives overnight into the first half of Thursday as a weak storm system and it's warm front pushes to our south. Some instability will be present, allowing a few embedded thunderstorms to be possible. Severe weather is unlikely.
