ICYMI Sept 20…Fog/Flooding Debris/Italy

It was a foggy start across parts of the KWWL viewing area Tuesday, especially northeast Iowa.  Dense Fog caused several school districts to delay the start of school for two hours early this morning.  Here’s the view from early this morning in Coralville and Dubuque on our Storm Track 7 Live Weather Network cameras.

This is the result of the Upper Iowa River flooding at the end of August. The debris field is located in the Big Slough in Pool 9, right across from Blackhawk Park near New Albin (Allamakee County). These photos were taken by Mike Brennan on Sunday.

A Foggy Start….For Some

1

A small area of Iowa had very thick fog early Friday morning with visibility less than 1/4 mile.

This was taken in Cedar Falls at 9:15 AM. There are houses about 200-300 feet away from where the picture was taken and the UNI is typically seen on the horizon. The bright light is the sun.

A Foggy Morning in Dallas, TX

The low clouds/fog were not very thick (vertically). The drone stayed lower than 400 feet. Here is the morning sounding (vertical profile of the atmosphere) from Fort Worth, TX .

Dec 9 FWD Sounding

If you watch the video above, once the drone gets above the clouds/fog the sky is clear and sunny. If you look at the sounding above you can see why. The red line (temperature) and green line (dewpoint) spread out indicating dry air resulting in a clear sky. At the bottom of the image (lowest part of the atmosphere) those two lines come together where the low clouds/fog were.

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.
