...Summary...
The National Weather Service in State College PA in cooperation 
with Warren County Emergency Management officials has confirmed
that a weak, EF0 tornado briefly touched down about 2 Miles to 
the North Northwest of Youngsville in Warren County 
Pennsylvania on April 20 2017.

Damage from the tornado included approximately 25 downed or 
uprooted trees, and roof damage to one home that included 
several large areas of roof sheathing and shingles torn off.

Several eyewitnesses, including local firefighters and County 
Emergency Management Agency officials, watched the funnel 
cloud track from west to east and touch down briefly about 
one-quarter of a mile to the west of State Route 27 or 
Matthews Run Road, before tracking east and lifting about 
100 feet to the east of Matthews Run Road. The tornado was 
likely on the ground for just a minute or two from 754 pm 
to 756 pm EDT.  

An interesting occurrence associated with the tornado was 
that light objects in the form of blankets and empty water 
buckets were sucked out of an open barn and pulled about 100 
feet north, to the center of the tornado path.
