We are currently watching two storms that are heading towards Ketuckiana. The first low (warm/moist) is moving out of Texas and is already producing moderate snow in Paducah. With the cold air already in place I think much of Ketuckiana will see just snow. However, with a little warm air advection tonight-Tuesday morning there is a good chance that areas to our south and east will see a rain/snow mix Tuesday morning, thus keeping their snowfall totals down. (Louisville-North should stay all snow)
The second low is packing some very cold air and gusty wind... and any areas that do recieve a rain/snow mix will see a change back to snow by early afternoon. With the temperatures falling into the 20s by late afternoon/evening any wet roads will quickly freeze. In addition, the winds by Tuesday afternoon/evening will gust up to 30 mph. This will most likely lead to some blowing/drifting snow and reduced visibility during the evening drive home.
We will continue to see scattered snow showers in the wrap around moisture Tuesday Night-Wednesday with additional light accumulation of an inch or less.
