Good Sunday afternoon bloggers,
The new 18z GFS is in and has a colder solution, so we would see more snow and sleet. The 18Z NAM was warmer and was looking like snow to start then sleet an freezing rain. If the upper low tracks farther south we could see a major snowstorm. If it tracks from western Kansas to eastern Nebraska, warmer air will be pulled farther north and freezing rain/sleet would be the main precipitation type. The cold air should get in deep enough to eliminate the chance of plain rain.
This is an unuusal storm due to its widespread warm air advection potential.
We will have a quick update when the new data comes out tonight, but Gary will have a much more detailed look Monday morning.
Have a great night!
