INDIANAPOLIS —
A Clipper system will move over the Great Lakes late Sunday night into Monday early afternoon.
Light precipitation will be possible. Model data shows that there is a warm air inversion above the surface. The sounding below shows the levels of the atmosphere.
The arrow in the image below shows the temperature inversion.
This inversion is close to the freezing mark, where the precipitation could melt.
If it does melt, it would land on a surface that is below freezing. That would cause the precipitation to fall as freezing rain. The image below shows how the warm wedge of air can change the type of precipitation.
It appears that if freezing rain occurs, it should be brief. Light snow showers will be possible, too.
