The week kicked off with severe weather in the mid-Atlantic as a line of storms brought damaging winds to areas from southeastern Ohio through eastern Virginia.
"Storms drastically intensified in central and eastern Ohio and continued to intensify as they approached Washington, D.C.," AccuWeather Meteorologist Alyson Hoegg said.
The worst of the storms focused on northeastern West Virginia, northern Virginia and the Washington, D.C., metro area where hail as large as quarters and wind gusts over 50 mph were common.
These strong winds brought down trees and power lines across the region, resulting in widespread power outages. In some cases, falling trees caused property damage.
Over 122,000 electric customers in Virginia and 20,000 in West Virginia were without power early on Monday night in the wake of the storms.
Travel delays mounted as the FAA imposed a temporary ground stop at Ronald Reagan Washington National Airport and Washington Dulles International Airport. This contributed to hundreds of flight delays and dozens of cancellations across the region.
The ground stop at Washington Dulles was put in place just minutes after the National Weather Service issued a tornado warning for an approaching storm; however, no tornado has been confirmed.
People in the airport took shelter at the airport's underground train tunnel until the storm had passed.
