At the moment it's 0/-9 here but was -7/-32 yesterday which is why they closed the schools. Normally it has to hit -20 (that's with wind chill) to close, and that's because so many kids wait for buses. Sometimes they'll have a one-hour delay, hoping it'll warm a little. Our school systems build in 3 "snow days" a year but seldom use them for snow. It's more often for extreme cold, the odd power outage or staff illness (there's a LOT of flu going around right now.)
