Really need watching

It is Wednesday and if you are following the weather a potential powerful low pressure system is expected to effect weather in West KY somehow then become a possible nor Easter type system. As far as winter weather chances the chances decrease as the low takes a more north westerly movement. Also timing is a big key because some models want to move it quicker than others. Also you have to watch to see how far the SE ridge will be suppressed, and the support and degree of the cold air the deeper the arctic high up around Michigan is the better. Even if Olga could have some influence on this system. If I had to make some forecast note this is an amateur / best guess forecast I would say this.

Henderson- Fri Night rain to snow showers changing eventually to snow Saturday before ending at nightfall. With a chance of accumulation and high temps a few degrees above freezing or right around freezing depending on degree of cold air

Hopkinsville/Murray/Madisonville- Fri Night rain, rain though first part of the day Sat changing to snow with less of a chance of accumulation probably a Dusting to an Inch if that. Any track that goes significantly northwest the snow chance is pretty much canceled unless you hope for a surprise on the backside.
