A round of severe thunderstorms swept across the northeastern United States Thursday and Thursday night, including a tornado just outside of Washington, D.C.

After a refreshing break from steamy air at midweek, warmer and more humid air fueled damaging thunderstorms across the region on Thursday.

A line of thunderstorms, which produced widespread wind damage across the Ohio Valley and also the violent tornadoes in Missouri late Wednesday night, marched eastward across the mid-Atlantic states Thursday morning into Thursday afternoon. Widespread wind damage occurred across parts of northern Ohio, northwestern Pennsylvania and western New York state during the morning hours. The line of storms began to lose intensity when crossing central Pennsylvania and the Appalachians during the midday.

This line re-intensified on Thursday afternoon sweeping through Baltimore and Washington, D.C. One storm was particularly strong, prompting a tornado warning to be issued for downtown Washington, D.C. A tornado has not been confirmed.

The force of the storm moved the Washington Mon mulberry tree off of its temp support causing additional damage to its limbs. Initial assessment is hopeful that it can be saved again, but we won’t do a thorough analysis until the hazard trees around the Natl Mall are cleaned up. pic.twitter.com/IEtSkWYE5i

Another storm that tracked near Baltimore spun up a tornado near Columbia, Maryland, which was confirmed to be an EF1 by the National Weather Service on Thursday evening.

A wind gust of 68 mph was clocked at Reagan National Airport as the storms blew through. These winds were strong enough to bring down large tree limbs, and in some cases, even blow over entire trees. Widespread tree damage was reported near the Lincoln Memorial and the Washington Monument at the National Mall in Washington, D.C.

Over 150,000 were without power late Thursday afternoon in Maryland and northern Virginia in the wake of the damaging storms. This number had dropped to under 100,000 on Thursday evening.

Another round of severe thunderstorms redeveloped across New York, Pennsylvania and West Virginia on Thursday evening, bringing isolated wind damage, brief, heavy downpours and numerous lightning strikes.

Trees with a weakened root structure from recent rainfall were most susceptible to being downed by thunderstorm winds, even if gusts are below 58 mph -- the lowest wind gust for a storm to be considered severe.

The storms brought times of reduced visibility for those getting a jump start on holiday travel.
