Conditions this morning vary across the state. Check 511 for current road conditions, and your local weather to determine what type of precipitation you may be seeing today. Plan your travel around the storm, not during - give the plows time to work. #VASnow pic.twitter.com/scQNWCW6Vt— VDOT (@VaDOT) February 20, 2019
