A saturated airmass with light winds will result in dense fog again overnight for much of the area. Over the south the fog is already beginning to thicken and shortly after sunset tonight, fog will become dense over much of the region. Travel will be difficult late tonight and Friday morning due to foggy conditions. Temperatures will remain above freezing but with visibility near zero at times extreme caution is advised.
A dense fog advisory will be in effect until 10 am CST Friday. Visibility will drop to below a quarter mile with visibility near zero at times. Driving will be hazardous due to low and changing visibilities. Allow extra travel time and please take appropriate precautions while driving.
