...DENSE FOG ADVISORY WILL EXPIRE AT 9 AM CDT THIS MORNING...

Observations of 1/4 mile visibility or less have decreased 
throughout the region as daytime heating and mixing of the 
boundary layer begins. Although dense fog has dissipated in most
areas, expect some visibility restrictions to linger as cloud 
decks remain low. Rain will transition to snow later today, 
causing all remaining fog to dissipate.
