Good morning bloggers,

Sunday begins with a Dense Fog Advisory. There is some freezing fog as well, with some frost forming on some surfaces providing a thin layer of icing. So, watch out for some tricky slick spots. Plus, we have had some refreezing of the ice melt from the snow. There hasn't been much melting yet, but any standing water on untreated surfaces may have some tricky icing that is hard to see.

Sunny & Rainbow The Weather Dogs show us the dense fog on the Country Club Plaza this morning. Visibility has been reduced to less than 1/4 mile in many areas. The fog is likely going to lift by early to mid-afternoon. There will be light winds to calm conditions today.

Another Storm System

There is a fascinating weather pattern setting up this week. Some blocking around 15,000 to 20,000 feet above us is forecast to develop over the North Atlantic. This can be seen below by looking at the H plotted:

The H is an upper level high height area that is forecast to close off. This is actually influencing the storm approaching our area around mid-week. When these blocks form, the models have a very difficult time predicting where they will form and track, and as a result the models are all over the place on the prediction of our mid-week storm system potential.

Some of the models are showing a storm system with snow over the KC region Wednesday night into Thursday. Other models have it too warm for snow. I am leaning in the snowier direction, but we need a couple more days to see how this trends. This model above shows the Canadian model.

The Blocking May Lead To Our First Arctic Blast

This map shows a brutally cold Arctic Air Mass trying to head south into the United States around the 15th to 20th of January. It is something we will be monitoring closely. We will discuss this in more detail in the next few days if it continues to show up. It fits the LRC almost perfectly to blast down around the 20th. It is the one part of the pattern that has been very cold in previous cycles. In October, it was very cold which lead to our early snowfall. So, it is right on schedule to happen around the 15th to 20th.

Kansas City Weather Time-Line:

  • Today: Dense Fog this morning reducing visibility to less than 1/4 mile. The fog will lift by early to mid-afternoon. High: 33°
  • Tonight: The fog may thicken back up again and it may be freezing fog with a light coating of ice possible by morning. Low: 25°
  • Monday: Morning dense fog lifting with some sunshine returning. It will warm up into the 40s. High: 42°

Thank you for spending a few minutes of your day reading the Action Weather Blog. Have a great Sunday, and Go Chiefs!
