Good luck on your trip.
I was also thinking they were having a more difficult than usual time predicting this storm.
We got about 9" so far. It rained about an hour ago for about 10 minutes, then back to snow. The latest radar had the freezing rain shifting to the north heading my way. With the snow cover, freezing rain is not an issue, except for power outages. They haven't plowed our road yet. The next best guess is another 4 to 7" by 7AM.
