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.
