Dense fog advisory issued for all of northern Illinois

Whether you have breakfast plans, plans to attend Sunday church, or plans to catch up on certain errands, travel with caution. 

A Dense Fog Advisory is in place for all of northern Illinois and southern Wisconsin as visibility in most of our locales has fallen to a 1/4 mile or less. This advisory will run until noon. Fortunately, temps are sitting in the upper 30s this morning, meaning the threat for freezing fog is extremely low. 

Fog should let up to a cloudy sky for the afternoon, limiting highs to the low 40s. 

Our next disturbance arrives overnight, leaving thick clouds in place but also bringing a chance for a passing shower or two. Temperatures stay warm, landing in the upper 30s. Monday will be a copy paste of Sunday, starting with some fog and then mostly cloudy for the afternoon. Highs will be slightly warmer, landing in the mid 40s.
