Severe thunderstorm, reported 70 mph wind, arrived on short notice

Rain-stalled traffic on Route 23 in Upper Merion Township.

The powerful thunderstorm that roared through the region Wednesday  with little notice evidently did more damage in the immediate Phladelphia area than its ballyhood predecessor on Tuesday.

With little notice, the storm struck right around the peak homebound commuting period.

National Weather Service reported a possible 70-plus mph gust in Pottstown just after 4 p.m. Numerous trees were downed in the region.

While Tuesday's outbreak spawned tornadoes in Berks County and southern Delaware, for PECO "it wasn't too bad" in the Philadelphia region, said spokesman Ben Armstrong.

Wednesday's was a more-dramatic story. "This was a quick pop-up, heavy hitter," said Armstrong, lasting only about five minutes. But the result was power knocked out to 30,000 customers.

Those outages were largely resolved by Thursday morning, with about 1,200 still lacking power.

The government's Storm Prediction Center had placed the region under a slight risk of severe storms, but no watches were issued.

The weather service in Mount Holly issued a severe-thunderstorm warning for the region just before 4:30 as the storm barreled eastward.

Tuesday's storms arrived in roughly the same time frame in the region.

Unfortunately, the peak commuting period is a favored time thunderstorms. They feed on heat, and this time of year they can get to feast on a day's worth.
