Tonight the forecast is for -28degC (that’s -18F for my American readers) and a windchill of -38degC … And not a whole lot warmer tomorrow once the sun rises. This is serious weather and probably as cold as it’s ever been hereabouts since we came to Canada 13 years ago. Definitely brass monkey weather, no question.
For those not up to date with the British vernacular of my youth the comment above rally means that nit will be cold enough to freeze the balls off a brass monkey. Cold.
