It has mainly been a rain event across Central and Eastern Kentucky today. That will change once we crossover into the overnight hours. Some much colder air will catch-up to the back side of this system. It will not be a slow process, it will happen rather quickly. So many of us will begin seeing snow develop during the pre-dawn hours on Monday.
A Winter Weather Advisory has been issued for parts of Eastern Kentucky beginning at 3am and it lasts through 2pm. The big concern there will be for light accumulations of snow. With a rapid drop in temperatures we could also see some black ice develop much quicker than you would normally see that happen. Black ice potential isn't just a concern for folks in Eastern Kentucky, I also think we'll see some in Central Kentucky too!
Our next main attraction doesn't start coming together until late Wednesday night and into Thursday. Models are slowly coming together on another system developing and impacting us beginning late Wednesday night. Initially, we'll see rain develop. Those showers will not last very long at all. The colder air ushers in and pushes rain over to snow. Now, the one thing that models haven't caught onto yet is a direct connection of moisture from the Gulf of Mexico and this cold air. If the two can come together... the snow chances would be a little more aggressive. At the moment we aren't seeing the two get together. It still looks fairly like we'll get snow from the front itself, but we need to watch it closely because it has even more potential.
