Ok. NO SNOW.. ( But Ice) .. Heres the map and explenation

Ok. So we get ice. I'm down with that. Here's my map and eplenation why. If you look Carroll County is in only a Freezing Rain Advisory, but very likely this will be upgraded to an Ice Storm Warning come Tomorow Evening. The only counties expected to get ice is the Eastern Blue Ridge Mountains, the western mountains are expected to stay rain. This is because the cold air damns up against the east side of the mountains. When a storm tracks west of us, it generally brings warm air up from the south, and drags it across our area. However, with the mountains in place, the cold air gets damned up on the eastern side of the mountains. Since cold air sinks, there is a VERY shallow layer of air at the surface. This ice storm will be very elevation dependent as you'll see on my map of Carroll County. 100 feet could make all the difference in the world. Roads I dont expect to be a problem, but tree limbs and power lines I do. With STRONG winds on the backside of the storm Power outages are a very strong possibility were ice acumlates.

Another aspect to the storm will be the snow showers on the back side. Expect several inches in the western mountains, due to the strong winds up against the mountains. A dusting to an inch are two is possible here, just depends on were the bands set up. I will post maps either later tonight, or early tomorow morning. If you live in Carroll Floyd or Patrick Counties and are above 2750 feet, be prepared for an ice storm tomorow night. If you live between 2000 and 2750, just light ice. Even though Patrick and Carroll Counties are not in an ice storm warning now, I expect that to change by tomorow evening, as the cold air will likely hold its ground.
