Difficult forecast to make today, we will have to wait to see exactly where the rain/sleet/snow line sets up across the state. I know it's a bit disheartening to see the same areas hit by the previous ice storm starting to fall in line for another one. Ice is still in on trees and powerlines at this time, so it won't take much to bring them down once more. The farther Northwest you are the more likely you will see accumulating snow fall of 8-12 inches. 


You can see from the HRRR model where it is thinking this line sets up. Freezing rain/ ice to the East in the pink, sleet mix in purple, and all snow in blue. If you are in Eastern Kentucky, be prepared once more for power outages and dangerous driving conditions.
