There’s few flakes so far, but the threat of as much as 8 inches of snow today has closed the D.C. Public Schools, most charter schools, the local and federal courts, not to mention D.C. and federal government offices. Forecasters are expecting today’s snowfall to be the most significant the city has experienced in three years. And once the snow is on the ground, the weather dangers will persist, with arctic air moving in and dropping temperatures into the single digits overnight and keeping highs down in the teens tomorrow. Also, if you’re planning to drive today, heed this reminder from the Capital Weather Gang: “Just want to drill into people’s heads that around 4 p.m. tomorrow – the beginning of the afternoon commute – may be a really bad time to be on the road.”
