I wouldn't worry too much. If you're in a rural area and have a generator, make sure you have gas. Maybe grab some extra food that is shelf stable if you don't keep much in the house. You don't need to be ready for nuclear war but having some basic food that will last you a week is appropriate.

Car stuff is useful to have too - ice scrapers, one of those snow pusher things, lock deicer, spare pair of gloves in the car. Snow pushers are amazing for heavy snowfall. Also you should have a spare shovel. A mini one in the car can come in handy too.

Most of us have been through 2+ feet in one night. When that happens things slow down for a day or so and then go back to normal.
