In the event that you leave your home make sure to pack a safety kit. Water, flash light, shovel, kitty litter/or sand, blankets, food, and your cell phone are a must! If you get stranded in the storm don't not try to travel by foot! Stay in your car and notify locals officials of your location.
Map still looks good to me:
Drifts 3-5 feet could cause some roads to be impassable even by truck. Also colder temperatures will allow to the snow to stick much quicker to roadways and road salt will be less effective. Enjoy and be safe!
