If not too windy that it will be blown away, treat paved areas the night before if you have advance warning. If you have to wait until the next day wait until your done shoveling so you dont toss your salt aside. Salting ice is obviously ok.

Make sure you have a straight hoe for chopping ice.

Plug your car in if it has an engine block heater.

Turn heat up in house in the event it goes out at a later time and does not return quickly, thus taking it longer for the heat to bleed out.

Do not take direct paths outside which will bleed heat even faster. IE, go out through attached garage if you have one.

Count on getting up early to shovel so your not leaving last minute to try and fly to work in bad conditions. Also packed snow can become slick and thats not fun when parking multiple vehicles in the same driveway.
