Here you go....-both maps were accurate for me. Took me hours to drive between College Park and Greenbelt. Cars abandoned everywhere. It snowed 3-4 inches an hour with drifts over 2 feet. And it was not forecasted. Mom was freaking out since there were no cell phones back then...

#OTD in 1987, a snowstorm hit the Washington, D.C. area, with up to 17" of snow and stranding cars for nearly 24 hours. The event led to the development of the Washington Metropolitan Area Snow Plan to facilitate preparedness and response. https://weather.gov/lwx/winter_DC-Winters #NWS150
November 11, 1987: The Veteran's Day Storm will not be forgotten by many Washington travelers. Almost a foot (11.5 inches) fell at National Airport. Prince Georges County, MD was hard hit with up to 13 inches of snow falling in a short amount of time. It caught motorists off guard and stranded cars on the Capitol Beltway. There were so many cars that snow plows could not get through to open the clogged arteries. Cars littered the roadway for more than 24 hours. The event precipitated the development of the Washington Metropolitan Area Snow Plan to facilitate preparedness and response to future storms.
This storm struck before the days of lightning detection networks and Doppler weather radar. When thunderstorms began dumping heavy snow over the Fredericksburg VA, forecasters had no idea. The storm moved northeast across the southern Metropolitan area (Prince Georges County). It was not until the fast accumulating snow hit Camp Springs, where at the time the Weather Forecast Office was located, did forecasters realize what was happening.
