ON THURSDAY EVENING, JULY 1, 2021, A SEVERE THUNDERSTORM MOVED EAST 
FROM ARLINGTON COUNTY INTO NORTHWEST WASHINGTON DC, GENERATING A 
TORNADO THAT PRODUCED INTERMITTENT WIND DAMAGE ALONG A 4.4 MILE PATH 
FROM THE WAVERLY HILLS NEIGHBORHOOD OF ARLINGTON TO NEAR 16TH STREET 
NW AND CONSTITUTION AVENUE NW IN DOWNTOWN WASHINGTON DC.  

WSR-88D RADAR IN STERLING, VIRGINIA, AND THE FAA TERMINAL DOPPLER
WEATHER RADAR FOR RONALD REAGAN WASHINGTON NATIONAL AIRPORT 
INDICATED THAT THE TORNADO TOUCHED DOWN AT 8:59 PM EDT IN THE 
WAVERLY HILLS COMMUNITY OF ARLINGTON. NUMEROUS TREES WERE SNAPPED 
IN MULTIPLE DIRECTIONS IN THIS COMMUNITY, NOTABLY IN AND AROUND 
WOODSTOCK PARK AND IN THE BACKYARDS OF RESIDENCES ON THE 4500 
BLOCK OF 20TH PLACE N IN ARLINGTON. ONE TREE IN WOODSTOCK PARK HAD
ITS BARK REMOVED AS A RESULT OF THE WIND. AS THE TORNADO CROSSED 
INTO THE CHERRYDALE NEIGHBORHOOD OF ARLINGTON, SEVERAL TREES WERE 
UPROOTED AND NUMEROUS LARGE BRANCHES WERE SNAPPED, SOME BLOCKING 
ROADS AND DOWNING POWER LINES. SOME HOMES HAD SIDING REMOVED. MUCH
OF THE DOWNED TREES AND BRANCHES FELL TO THE EAST, BUT SOME FELL 
TO THE NORTH AND NORTHEAST AS WELL. MAXIMUM WINDS WERE ESTIMATED 
TO HAVE REACHED ABOUT 90 MPH, AN EF-1 ON THE ENHANCED FUJITA 
SCALE.

WIND DAMAGE JUST SOUTH AND SOUTHWEST OF THE TORNADO TRACK WAS 
DETERMINED TO BE THE RESULT OF STRAIGHT LINE WINDS. THIS DAMAGE 
BEGAN NEAR I-66 BETWEEN VA-267 AND US-29 IN EAST FALLS CHURCH, AND
CONTINUED EASTWARD SOUTH OF THE TORNADO TRACK THROUGH WESTOVER 
AND VIRGINIA SQUARE, GENERALLY ALONG WASHINGTON BLVD. NUMEROUS 
TREES AND LARGE LIMBS WERE DOWNED. MULTIPLE TREES FELL FACING EAST
NEXT TO THE CRESCENT ON N WESTMORELAND STREET DAMAGING A FENCE. 
ONE TREE AND LARGE LIMBS FELL INTO A HOME IN THE 4300 BLOCK OF 
16TH RD N, INJURING AND BRIEFLY TRAPPING A RESIDENT. THERE WERE 
ALSO NUMEROUS TREES DOWNED AROUND WASHINGTON-LIBERTY HIGH SCHOOL.

THE TORNADO CONTINUED EAST OVER THE LYON VILLAGE NEIGHBORHOOD, 
DOWNING SEVERAL TREES AND NUMEROUS BRANCHES ACROSS THE NORTH END OF 
THE COMMUNITY, INCLUDING AROUND THE COMMUNITY CENTER. THE TORNADO 
WEAKENED SLIGHTLY AS IT MOVED INTO THE COURTHOUSE COMMUNITY, PASSING 
JUST NORTH OF KEY ELEMENTARY SCHOOL, CONTINUING TO SNAP LARGE 
BRANCHES AND DOWN POWER LINES. DAMAGE BECAME HARD TO IDENTIFY AS 
THE CIRCULATION CROSSED THE HIGHLY URBANIZED AREA OF ROSSLYN, BUT 
EMERGED AGAIN AFTER THE TORNADO CROSSED THE POTOMAC RIVER AND 
ENTERED THE DISTRICT OF COLUMBIA.

THE CIRCULATION LIKELY CROSSED THE POTOMAC RIVER NEAR THE THEODORE 
ROOSEVELT BRIDGE. THE FIRST SIGN OF TORNADIC WIND DAMAGE WAS AT 
THE WEST END OF THE NATIONAL MALL, WITH A SNAPPED HARDWOOD TREE ON
THE MALL ON 23RD ST NW BETWEEN CONSTITUTION AVENUE NW AND LINCOLN
MEMORIAL CIRCLE. TREE DAMAGE AROUND THE LINCOLN MEMORIAL AND 
FURTHER SOUTH INTO WEST POTOMAC PARK AND NEAR THE DC WAR MEMORIAL 
WAS DETERMINED TO BE CAUSED BY STRAIGHT-LINE WINDS. HOWEVER, 
ACROSS THE MALL ALONG CONSTITUTION AVENUE NW, WIND DAMAGE TO 
TREES ON THE MALL PARALLELING CONSTITUTION AVE NW WAS PROMINENT 
FROM 23RD ST NW EAST FOR 0.75 MILES TO NEAR 16TH STREET NW SOUTH 
OF THE ELLIPSE. TREE LIMBS FELL TO THE NORTH ON CONSTITUTION 
AVENUE NW, ORTHOGONAL TO THE STORM’S MOTION, INDICATING 
CONVERGENCE AND ROTATION. CONCENTRATED DAMAGE AT THE NORTH 
PORTION OF CONSTITUTION GARDENS WAS CHAOTIC AND CONVERGENT, WITH 
HARDWOOD LIMBS AND DOWNED TREES FALLING IN MULTIPLE DIRECTIONS, 
INDICATING THE TORNADIC CIRCULATION. FINALLY, THE LAST DISCERNIBLE
TORNADIC DAMAGE WAS TO TEMPORARY FENCING ON THE MALL THAT WAS 
INSTALLED FOR THE INDEPENDENCE DAY CELEBRATION, DIRECTLY ACROSS 
FROM THE ELLIPSE. THIS FENCING APPEARED TO HAVE BEEN LIFTED UP AND
TWISTED, LANDING IN A MANGLED AND HAPHAZARD MANNER.

THE NATIONAL WEATHER SERVICE THANKS ARLINGTON COUNTY'S OFFICE OF 
EMERGENCY MANAGEMENT, THE DISTRICT OF COLUMBIA'S HOMELAND 
SECURITY AND EMERGENCY MANAGEMENT AGENCY, THE MEDIA, OUR SKYWARN 
SPOTTERS, AND THE PUBLIC FOR THEIR ASSISTANCE IN IDENTIFYING 
DAMAGED AREAS.

ORTHOGONAL TO THE STORM’S MOTION. NUMEROUS SMALLER TREE LIMBS 
WERE DOWNED IN THIS AREA.
