Dense Fog Advisory

It's been a very foggy day out there as visibilities are continuing to deteriorate across much of the viewing area. A dense fog advisory has been issued for Carrol and Whitesidecounties until 9 PM this evening. A dense fog advisory has also been issued for Winnebago, Boone, McHenry, Ogle, Lee, and Dekalb counties until 4 AM tomorrow morning.

With this fog being so dense, this will contribute to visibilities being as low as a quarter of a mile or less in some areas. Temperatures right now have dropped into the low 30's for areas underneath this dense fog layer. Places to our northwest, however, such as Galena and Monroe are a bit warmer as the fog up there has dissipated.

Take it slow on the roads and be sure to give yourself extra time on the commute Saturday morning. How quick the fog evaporates tomorrow morning will have an impact on just how warm temperatures will be Saturday afternoon.  The longer the fog sticks around, the cooler the temperatures will likely be across the viewing area.
