The local Peoria Red Cross has opened their winter shelters (a full list of winter shelters are available). They are also urging motorists to stay off the road. The blizzard conditions are going to create havoc, especially on open country roads.
The storm should last a day or so. While you're snuggled up inside (whether or not you lose electricity), make sure you drink plenty of water. The precipitation tends to suck much of the moisture out of the air, making dehydration a real concern.
If your power does go out, make sure you unplug your appliances. That way, when the power does surge back into your house, you'll ensure that the electronics don't get overloaded.
Be smart, and be healthy. Playing in the snow is fun, but please dress warmly. Let's get through this thing without frostbite. Hopefully you already stocked up on batteries, lamps, and food (Peoria's grocery stores were extremely busy yesterday). Good luck to all, and enjoy the show out your windows!
