Go out and buy forty-seven eleven bags of groceries that you don't need and won't eat if the electricity goes out. But be very virtuous and make sure its things that can be warmed up on the wood stove and non-perishable. Also make sure that you stock up on chocolate and dry roasted peanuts.
Make a big pot of soup. Cook up any perishable food that you can.
Put out big bales of hay for the sheep, and fill their water troughs. Make sure the two wheeler cart is somewhere it won't freeze to the ground in case the sheep can't walk to the round bales and you have to feed square bales. (The fact that you have to crawl and slide around is besides the point)
Make sure there is a shovel and pick in the hallway, and not safely tucked away way out in the garage, in case you have to hack your way out the yard gates.
Fill up the wood box, inside and in the hall way. Cram as much wood in there are as you can without causing a wood avalanche.
Put sandbags for weight in the back of your truck.
Get out your winter insulated chore boots, so your toes will quit freezing off.
Fill every bucket and container you own with water, 'just-in-case-the-electricity-goes-out-for-thirteen-days-or-so'.
Drape plastic sacks over gate latches so you might be able to open them in the morning.
Check your 'getting stranded at home survival kit'.
Know in the back of your mind that you are forgetting to do something crucial.
Fix more cat boxes in the hallway, because heaven forbid one cat would have to share it's sleeping quarters with another.
Turn all the lights on and enjoy them, just in case.
Eat chocolate donuts and drink coffee, so you already nervous nerves can get even worse.
Find a warm place as close to the fire as you can, and snuggle down and go into denial.
Get depressed, because even if it doesn't happen, it might.
