11 thunderstorm wind, 5 tornado, 4 hail. Local standard time, as filed.
Nickel-sized hail, combined with wind gusts up to 60 mph, occurred at Catonsville in southwestern Baltimore Co.
Marble to ping-pong ball sized hail was reported in the Kensington area, with several reports from the Capital Beltway between Connecticut Avenue and the Mormon Temple.
Straight-line winds tore a portion of sheet-metal roof off a Ryder rental center and deposited it onto an emissions inspection center next door. As the storm tracked north-northeast, more roof damage occurred at Damascus High School, about 10 miles away.
A wind gust of 60 mph was reported in Mount Airy.
Dime-sized hail was reported in downtown Washington.
A microburst felled hundreds of trees, causing substantial damage. A large tree crushed a home in the Tannery Road area. A swath of trees was blown down in a band 50 to 75 feet wide. Other trees were blown down by the microburst at the Maryland Midland Railway, which runs alongside Tannery Road. Powerlines were also knocked down; service was cut to 6,240 customers shortly after the storm moved through.
Dime sized hail fell in Columbia.
Nickel-sized hail, combined with wind gusts up to 60 mph, occurred at Catonsville in southwestern Baltimore Co.
A microburst surged through Riviera Beach, causing extensive damage to a 30-block area in the town. A total of 12 homes were damaged, two extensively. One home was nearly destroyed when a 5 foot diameter oak tree fell. Another home suffered damage to its exterior electrical system. A 4-foot diameter tree crushed a shed, and another shed was thrown a short distance before disintegrating. Numerous small trees, and hundreds of branches, were blown down by the storm. Widespread power outages were noted across northern Anne Arundel Co, with 5,000 customers without power shortly after the storm. Other less significant damage occurred to sidings and shingles. A chimney was damaged, and a few windows were blown out.
Two devastating tornadoes ripped through working-class neighborhoods in central Baltimore City, causing upwards of $3 million in damage to 150 buildings. Up to 200 families were displaced by the storms. Although the damaged neighborhoods were not declared federal disaster areas, FEMA officials were helping the city's Department of Housing and Community Development prepare applications for federal aid from HUD. The West-Central tornado began near the intersection of Edmonston Ave. and Monroe St, and moved northeast, just past the Harlem Park Elementary School. The storm continued down Mosher Street before lifting at Mason Avenue a few blocks west of Interstate 83. Many roofs were blown off row houses in the Harlem Park area. Windows were blown out, and some building sides were blown down. The East-Central tornado began near the intersection of Federal Street and Greenmount along the west side of Greenmount Cemetary. The tornado travelled east-northeast across Aisquith Street and the 1200 block of North Avenue, where the heaviest damage of all the storms was realized. The tornado continued to Harford Road before lifting just west of Clifton Park. Similar damage, to the upper floors and roofs of row houses, occurred with this tornado. Amazingly, no one was injured or killed, perhaps since the most affected were either at work or school. A few eyewitness claim they saw a funnel cloud prior to damage occurrence.
A wind gust to 74 mph was recorded at Glyndon Elementary School in Western Baltimore Co.
A wind gust of 79 mph was recorded at Northern High School in Baltimore City.

A microburst caused more than $100,000 in damage to a private airfield in northwest Calvert Co. One hangar was destroyed, and the roof of another hangar was thrown 1,000 feet, destroying an antique single-engine piper cub. Planes being rebuilt in the destroyed hangar sustained minor damage. Trees and power lines were also knocked down by the displaced roof, causing over 4,000 Southern Maryland Electric Co-operative customers to be without power.
Straight-line winds knocked down several trees in Gunpower State Park, approximately 2 miles southeast of Glen Arm.
Straightline winds associated with a thunderstorm gustfront blew a tractor trail truck on its side on Riverside Parkway near the overpass to Interstate 95 at exit 80. Some nearby trees were also toppled.
The squall line which produced earlier tornado and microburst events in central Maryland continued to wreak havoc in eastern Harford Co. Two F0 tornadoes produced minor roof, siding, and gutter damage, as well as softwood tree damage, in a relatively narrow path. More substantial damage occurred at the Perryman Unit 1 Baltimore Gas and Electric Facility, where a 70 ton air duct, 12 feet high and 50 feet wide, was blown off an elevated steel girder platform (20 feet high) into the side of an electrical control building, destroying most of the building. Eyewitness in the vicinity also watched an 8- by 30-foot trailer become airborne before blowing apart. Debris was seen rotating as it descended into a nearby field.
Trees and power lines were felled as the same squall line continued into extreme northeast Maryland. Hardest hit areas were Port Deposit, Rising Sun, and Conowingo. A large oak tree destroyed a southbound automobile in neighboring Lancaster County, Pennsylvania, killing the driver and seriously injuring the passenger. The couple were from Conowingo, Maryland.
