The storm struck Saturday afternoon and caused widespread damage. While repairs and cleanup efforts were ongoing, some customers remained without electricity as another heat wave approaches.

In Wynnewood, resident Jane Lippincott said the storm's impact was sudden and severe.
"I was in shock, and it just was horrible. I didn't know what to do," she said.
Lippincott said the storm did not last long, but a 40-foot oak tree in her backyard fell and left significant damage behind. She said it was unclear how long it would take for the debris to be removed and for power to be restored.
"I've been reading a lot. One of our neighbors said it's like Little House on the Prairie again," she said.
A few blocks away, strong winds sheared the tops off several trees, causing severe damage to a home and a vehicle parked in the driveway. Neighbor Dechun Chen said, amazingly, his home escaped major structural damage.
"Fortunately, the house, the frame, still good," Chen said.

Similar damage was reported in West Philadelphia. The National Weather Service confirmed that at least four microbursts produced straight-line wind gusts of 60 to 70 mph between 2:30 p.m. and 3:15 p.m. Saturday.
In Lower Merion, officials said resources remain available for residents without power.
"They are still available for residents who do not have power at their house. There's cooling and charging stations and they are at our local fire stations throughout Lower Merion Township," said Lower Merion Police Superintendent Andy Block.
PECO reported that after tens of thousands of customers lost power during the storm, fewer than 2,000 remained without service as of Monday evening.
Utility officials said they hoped all remaining customers would have power restored before Tuesday.
