Baltimore is bracing for a significant temperature drop as an arctic air mass sweeps down from Canada, through the Great Lakes, and into the Mid-Atlantic region. According to justinweather.com, temperatures will remain below freezing, with wind chills plummeting into the single digits and teens. This cold snap marks the coldest day of the current stretch, with high temperatures only reaching the upper 20s.
