Cold Weather/ Snow/ Ice Hints for those not used to it:

For those of you who are undergoing colder than usual snowier icier than usual conditions my sympathies. I used to live in southern Ohio where a couple of inches of snow meant the school buses wouldn't run, then we moved to the Boston area to a town that was proud of how 'tough' it was and unless it was two feet deep and blizzarding all at once you were expected to be in class on time. A shower in the morning meant frozen hair by the time I stepped through the school door.

Now I live in Alaska, which has been having far better weather than a good deal of the rest of the U.S. Go figure. So if you are feeling out of sorts due to sub-normal climes, hope this helps:

Your health:
Stay hydrated. Drinking an extra pint of water or more will help keep you warm in that cold tends to dry the air out and promote your body losing water through evaporation direct from your skin you are not aware of.
Feeling cold: Feeling cold when it's cold is normal. If you're reading this odds are pretty good you're a mammal. Since you generate your own heat chemically your surface is going to let you know that the outside temperature isn't quite the same. Being cold can be quite refreshing. What isn't cool is being numb. If you are really unaccustomed to this slice of weather, introduce yourself to it by degrees, (ha-ha). If you are nervous, try to meet up at Starbucks with someone who thinks that cool is cool.

Pets
Help your pet stay hydrated. You might be bringing outdoor pets inside. They'll need water too. If they are still outside, they need access to liquid water. If you need to walk your dog, you may find your dog has a high metabolism and can handle cold weather. If the dog is not used to snow and ice, the dog may be enjoying the novelty but subject to injuries like not stopping in time or especially splayed legs, particularly hindquarters. You may think this calls for doggie booties but in Alaska not many people use them unless their pets have unusually hairy foot pads or are used for mushing. They may reduce a dog's traction and they often slip right off. Some shorthair dogs get a tie-on blanket, but the dog I'm most familiar with is a 50 pound lab-mix who has never appeared to be cold and starts eating snow (a sign of overheating) at under 20 degrees F. Dogs have their own personalities and may or may not like the experience. Keep 'em hydrated.
If you like to give your pets the 'freedom' of the house, particularly birds and reptiles, you may want to reconsider this while the unfamiliarity with outside temps may present a danger. They can get lost, cold, and predated in no time. Large snakes are actually hard to kill, but if they can wander off, they will, and then hang out comatose for months.

Your car:
Your car needs tires that will grip the road. And while 4 season tires and studded tires may accelerate better than worn or high speed tires, they might not stop any better. Tire chains are available for real emergencies and there are some that are not hard to put on and will allow you to get to a relative, neighbor, or hospital if you are dependent on your own resources. (My first chains were totally plastic and nylon and were serviceable for years). But a taxi or uber is easier and cheaper.
A modern car has two separate stores of water: A small one for windshield cleaning and your radiator coolant system. Typically the latter ara mix of glycol and water. Unless the temp is going down to 0 Fahrenheit (= -17 Celsius) don't mess with it. If you have pure water/ soap solution in the small plastic windshield cleaner fluid tank consider topping it off with a lower temperature mix.
Stuff you may keep in your car: leaving your Starbucks water in the cup holder will result in frozen water, but leaving a can of soda pop in your car will create a mess. Alcohol wipes may be too cold to use.
Having a 'survival' package is a good idea. Likewise one of those backup lithium batteries specifically to start your car. You can pick up both at Costco (except maybe now). A survival package consists of:
Jumper cables and the instructions for using them (Positive Dead to Positive Live; Negative Live to Negative Dead)
Reflective or lit markers to guide traffic around your stopped vehicle.Have a USB cord in the glovebox so you can charge your phone from your car.

Have some large plastic trash bags for wrapping stuff up, such as a guitar you might want to protect from melting stuff.

Beware of bridges over AND under. In cold weather the upper level of bridges may have a frozen surface. Underneath the bridges the snow may not be completely cleared or have mixed surfaces, some stuff frozen, some not.

Dressing for the cold without buying a winter coat:
You want to cover your head , your neck, and in place of a thick coat, layers layers layers. If you have old wool clothes, they will warm you even if they are wet. Cotton will warm you if it is dry and thick. It will not be good to wear if it is wet. Likewise with silk and most polys. Your outer layer should be windproof.

Fall protection:
I'd say that your main danger is the many opportunities you can have to go ass-over-teakettle, especially on your own property or walking around your own car. Even healthy young people can break bones with no forewarning. Many of us are older and slower to heal. Lay in a supply of salt for your walkway and driveway. You can also use kitty litter. it is better to put it down over a cleared area, not to drop it right in the fallen snow. It is a good idea to have a box or bag of it in your car as well, along with a portable shovel. (In my case a wok once proved serviceable).
Traction devices for your shoes. You don't need to go for full on crampons. They are more of a hindrance off of the mountains. There are many many slip-over kinds. I like to work for a place that uses workmen, find out what they give their people, then steal a pair. But often Costco has something almost as good. The kind that work in your driveway and your workplace parking lot may be the lightweight kind with what appears to be small metal springs wrapped horizontally around rubber strands. They work, but they wear out real fast. They are not good for long walks where they might contact different surfaces. The spring part deforms and wears through the rubber part. The more robust kinds iwith actual chains or hard metal points under your soles and heels will dig into ice are way better. There are a couple of brands for sale at REI that are real good, but they cost several times as much. They are trail worthy and long lasting.

Shoveling snow. You may have a service to clear your driveway. If you have to do your own walk, and are a little afraid of the effort and what it could do to you, you can either look for help or have a go at it yourself. If you do, pace yourself. Fresh fallen loose snow is usually easy and a novelty exercise. Snow that has been rained on is called 'heart-attack snow.' If the weather predictions are for a return to warm temperatures, wait it out. or, take a small shovel and- pace yourself.
