The National Weather Service in State College PA has confirmed a tornado near North Warren in Warren County Pennsylvania on June 5, 2016.||The tornado developed in woods west of Route 62 before coming down a hillside into North Warren. It crossed Route 62 and strengthened to an EF-1 tornado moving through a heavily wooded area at a cemetery and between homes. All the trees were felled, many in a criss-cross pattern. Healthy hardwoods were uprooted. Other trees and softwoods were snapped. Minor damage occurred to homes protected by the much taller trees with just some shingles, flashing, and windows impacted by the wind. One guest house near Conewango Creek was destroyed when a tree demolished it. The tornado then crossed Conewango Creek, devastating large trees around a large estate, crossing Conewango Avenue and several more properties. Again, there was some shingles and flashing lost, but most of the damage was the snapping and uprooting of trees in the path with damage to a house and garage due to fallen trees. The tornado weakened as it approached Holly Apartments and ended upon reaching a hillside behind the apartments.||Peak winds were estimated at 95 mph. There were no injuries or fatalities.

No tornado warning for this county appears in the archive as in force at the moment the tornado touched down.

Every warning and watch covering the touchdown point that day, from the Iowa Environmental Mesonet's archive of National Weather Service products. Lead time is measured from the issue of the warning in force to the touchdown time in the database, both of which were recorded to the minute by different people.

The Storm Prediction Center had this point in a Slight Risk. The outlook in force was issued at 19:57 UTC.

SPC's Day 1 convective outlook as it stood when the tornado began, read at the touchdown point. The same archive is on the radar archive.

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
