Here's what I expect in terms of snowfall, mostly on grassy surfaces, by 2 AM Wednesday. See map below. Take the higher number of my snowfall "range," if you live on a hill or on a higher elevation. I believe the storm timeline, (the second picture below), is still on target for the Valley...the changeover to winter weather will occur much sooner in the day Tuesday for the Plateau and Southeast Kentucky. Travelers, be advised.

The value of a forecast is not just what you say, but when you say it.
