Dense Fog Advisory

The fog has gotten thick fast this evening lowering visibility to 1/4 or less in many locations. The fog will remain through early Thursday morning. 

Here is another look at the temperature profile from Davenport. The sounding gives us a good look at how the weather conditions change as you get higher in the atmosphere.

A Foggy Start

The locations outlined in yellow are reporting foggy conditions at 7 AM. The fog is in eastern and central Iowa while the western part of the state has a clear sky.

Because the wind is light and will remain that way it will take a long time to mix the atmosphere up to thin out the fog. We might have to wait until some time this afternoon to get in on some sunshine.

Here are a few recent web cam images showing the foggy conditions. Don’t forget to turn your lights on when traveling in the fog.

 

Here is the morning sounding from Davenport. The clouds and fog are not very thick at all.
