Yes, we call this cold, even in Alaska.
My public service announcement (for families living with cold winters and pre-schoolers) via WFMW:
As part of your cold-weather emergency gear in the back of your car, include a sled big enough to haul all of your littles. This will help save your neck (back, fingers, toes…) if your car breaks down.
I don’t know about any of your pre-schoolers, but one of mine is a molasses child: she moves slower in the cold– complaining of her agony and how much she wants *out* of the cold.
There’s a sled in the back of my car because if we ever were stuck in temperatures like these, her pace would be a literal safety hazard, since there’s no moving faster than the slowest member (and I can’t carry two kids very far).
And, for people whose minds move to fun faster than mine, you’ve already realized keeping a sled in the back means you can stop and go sledding whenever you find a good hill. And that’s worth a lot too :)
