A line of potent thunderstorms that blitzed through the region Monday evening at turnpike speed set off tornado alarms and flood advisories, took down trees and wires, and resulted in more than 135,000 power outages.

Tornado warnings were issued in parts of Philadelphia — where thousands of outages were reported — and for northern Chester County and parts of Montgomery County. A funnel cloud was sighted near Coatesville, the National Weather Service said.

The weather service was flooded with damage reports, said Dean Iovino, a lead meteorologist with the Mount Holly office, however no tornado had yet been confirmed.

A gust of 55 mph was measured in Glenside, Montgomery County, and multiple trees were reported downed throughout the region. A downed tree blocked an eastbound lane of the Schuylkill Expressway near King of Prussia.

Heavy rains prompted a flood advisory for Chester and Delaware Counties and northern Delaware. However, it was later lifted, likely the result of how swiftly the potent line was moving. “Once it got to our area it kind of sped up,” Iovino said.

The storm threat resulted in the postponement of the Phillies game against the Washington Nationals, which will be made up as part of doubleheader on Tuesday.

That turned out to be a prudent decision, because the storms were at their peak ferocity around the scheduled start of Monday’s game 6:40 p.m.

Forecasters over the weekend were warning of the severe threat, and the government’s Storm Prediction Center on Monday had issued a tornado watch for Philadelphia and all of eastern Pennsylvania, South Jersey, and Delaware.

Sunshine was abundant in much of the region Monday, but it was not particularly welcome, said Iovino. That additional energy, he said, just helped to “further destabilize conditions.”

The Philadelphia region endured one of the stormiest Julys on record, in which the National Weather Service issued 123 severe-thunderstorm warnings throughout its service territory, which includes all of Delaware and most of New Jersey. It’s the second-most since they began keeping records in 1986, only behind July 2021, when the service issued 132 warnings. The average number of thunderstorm warnings for July is 47.

Thunderstorms were observed officially at Philadelphia International Airport on 15 different days in July — five more than in 2021, according to weather service data. The long-term average for the month is 5.8.

Monday’s thunderstorms were the first in the last eight days. That was the longest streak without a thunderstorm in Philly since May, according to weather service records.

On the brighter side, the weather forecast looks pleasant for Tuesday and Wednesday, with temperatures in the mid-80s and little chance of rain. The next potential storm in the forecast is for Thursday, where scattered thunderstorms could develop later in the day.
