The National Weather Service said it would review new reports of a funnel cloud seen during the destructive storm.

The weather service had said Friday morning it would not conduct a storm survey in the county, where a barn was destroyed in White Township and where numerous trees and branches came down.
Additional reports of damage that came in Friday prompted the change of plans, weather service meteorologist Sarah Johnson said.
Asked whether there is a possibility a tornado touched down, Johnson said: "We don't know. That's one of the things that ... we'll be going up there to determine."
'No tornado,' but 1 hurt, debris to be cleared
Frank Wheatley, county public safety director and emergency management coordinator, said additional reports came in Friday that prompted him to request the survey.
"I believe that there are now four witnesses who have come forward to attest to a funnel cloud in the area of the Smith farm on (Route) 519," he said. "That along with the treetop damage might be an indicator of a possible funnel cloud."
The weather service says it is sending a survey team to Warren County from its Philadelphia region forecast office in Mount Holly, New Jersey, to conduct the survey between 4 and 6 p.m.
"A final assessment including results of the survey are expected to be completed and transmitted via a Public Information Statement between 6 and 7 p.m.," the weather service said in a statement at 2:25 p.m. Friday. "It will also be available on our website, which can be found at weather.gov/phi."
In addition to the barn damage, one person was reportedly injured at Oxford Furnace Lake and thousands of properties lost power, according to FirstEnergy's JCP&L.
