After high temps in the mid-50s, today winter is forecast to return this evening. Early this evening temperatures look to fall as much as 20 degrees from today's highs as an upper air system moves into Kentucky from the northwest. Temps look to fall into the mid-30s. Which will be just cold enough for some wet snow to fall. The windchills will make it seem much colder. Windchill factor will be in the low to mid-20s by Monday morning. The time period of all the map simulations is 6 pm to 6 am EST Sunday night till Monday morning.
