The SPC has issued a Mesoscale Discussion for heavy freezing precip to the Southeast of Wichita- let’s take a look.

The area in purple, but especially the hatched area within that area has the potential to see significant icing overnight tonight into the morning hours. The rate of icing looks to be .05″-.1″ per hour with the band of moisture moving NE from OKLAHOMA. 
Here is that area of moisture:

This large area of moisture is producing significant icing SW of OKC.

Here is the accumulation potential for the highlighted area.

  This area of wintry precip as well as what is moving in behind it could cause slick spots and travel troubles on elevated roadways untreated more rural roads.

If you must travel- please be safe and aware that you may encounter slick roadways.

Good night Weather Watchers
