Arctic air is sweeping into metro Detroit, bringing the coldest temperatures of the season and forcing many schools to close this Friday. With wind chills expected to plummet as low as -25°F early Saturday, a Cold Weather Advisory is in effect until 10 a.m. Saturday. Highs will barely reach the single digits, and overnight lows could dip well below zero. For families, this means a sudden change in plans—check the latest school closure lists and stay safe indoors. How are you planning to keep warm and keep the kids busy during this deep freeze? #Education #DetroitWeather #SchoolClosings
