Wow, a record low ... MINUS 37 Celsius on the outside thermometer! It shows that the warmest it got yesterday afternoon was -19C and the coldest it got overnight was -37C, and that the battery is sort of low! Many car batteries won't start this morning and electrical cars? Forget it, not made for this temperature. And ... there's the windchill factor! With a slight breeze, it feels like -45C!
