...SUMMARY...
THE NATIONAL WEATHER SERVICE IN PITTSBURGH CONDUCTED A STORM
SURVEY IN THE PARKER, PA AREA WHERE A EF1 TORNADO WAS CONFIRMED.
THE DAMAGE STARTED ON PARKER PIKE ROAD WHERE NUMEROUS HARDWOOD
AND SOFTWOOD TREES (CLOSE TO 100) WHERE EITHER UPROOTED, SNAPPED
AT THE TRUNK, OR BROKEN HALFWAY UP. AS THE STORM MOVED CLOSER TO
THE CITY OF PARKER ON THE BORDER OF ARMSTRONG AND BUTLER COUNTIES
STRUCTURE DAMAGE WAS REPORTED AS A STORAGE TRAILER WAS OVERTURNED,
AN EXTERIOR DETACHED GARAGE LOST MOST OF ITS ROOF, AND A WALL 
FROM A TRUCK WASH HAD A WALL BLOWN OUT. THERE WAS EXTENSIVE TREE 
DAMAGE WITH TREES ON HOMES ALONG CENTURY STREET. 

THE STORM LIFTED AS IT APPROACHED THE ALLEGHENY RIVER. THERE WERE
REPORTS OF DOWN TREES SEVERAL MILES EAST ALONG CONCORD CHURCH 
ROAD IN CLARION COUNTY WHERE THREE LARGE OAK TREES WERE UPROOTED,
HOWEVER THIS WAS CONCLUDED NOT TO BE A RESULT OF THE TORNADO, BUT
STRAIGHT LINE WIND (GREATER THAN 65 MPH). 

THIS IS THE 14TH DOCUMENTED TORNADO IN ARMSTRONG COUNTY AND 
25TH ONE IN BUTLER COUNTY SINCE SINCE 1881. THE LAST TORNADO IN
ARMSTRONG COUNTY HAPPENED ON APRIL 28TH 2002 AND WAS A EF0. THE 
LAST RECORDED TORNADO IN BUTLER COUNTY WAS JULY 10TH 2017 AND ALSO
WAS AN EF0 TORNADO. 

INCLUDING THIS TORNADO, WE HAVE RECORDED 11 TORNADOES SO FAR THIS
CALENDAR YEAR IN OUR COUNTY WARNING AREA. WE TYPICALLY AVERAGE 
FIVE A YEAR, SO WE ARE WELL ABOVE AVERAGE. 

WE WOULD LIKE TO THANK THE ARMSTRONG AND BUTLER COUNTY DEPARTMENT
OF PUBLIC SAFETY FOR THEIR HELP.
