Hope everyone is coping well. This is a time your preps really show there value. One of the best things you can do is stay at home (if you can) and watch the show from your livingroom.
I'm in northern Canada, where snow is part of our character. That said, there are still plenty of stupid people doing stupid things. The roads are a dangerous place at the best of times, let alone when people exceed their skill level.
Snow-on-ice driving is like driving on ball bearings. I've seen people panic when sliding and hammer on the brakes, only to slide slowly directly into another car. When your brakes lock, your vehicle continues in a straight line. With ABS and slippery conditions, your vehicle continues in a straight line and makes lots of noise. If you find yourself sliding with the brakes on, put your tranny into neutral - you'd be surprised how much faster you'll slow down.
If you drive into snow that's a little too deep, don't panic - add a little more gas and try maintain your speed. You'll be surprised how much snow you can make it through if you can keep up your momentum. If you start to slide, keep your wheels pointed where you want to go and KEEP PLOWING. If you do get stuck, your probably stuck good. This is because all the snow under the vehicle adds a lot of friction, and with the reduced traction, you can't move. Take your shovel out (of course you have one) and go to town under your vehicle as well as around the wheels.
And for 4-wheel drive newbies that think they can conquer the world, as all the dirt demons will tell you, 4-wheel drive is for getting you out of trouble, not into trouble. I've heard of many people (including my brother) who put their vehicle into 4 wheel drive on the highway when their truck slid a bit and carried on their merry way, thinking they solved the problem. This works fine until they go around a corner and slide into the ditch. This is because when you are in 4-wheel drive and have locking differentials, something has to slip, so you are actually adding slip at a time of poor traction. Not good. Just slow down. Wave at the guys who pass you, you'll meet them later. That's why you have the shovel, if you're nice

Good luck and take care.
