The winds that lifted off the roof of an elementary school building in Berks County on Thursday belonged to a tornado, the National Weather Service confirmed Friday.

The twister – an EF1 on the Enhanced Fujita scale -- packed winds of 105 m.p.h., traveled about three-quarters of a mile and left a damage path 75 yards near Tilden Township. One person was injured.

The weather service said the tornado touched down near stone road, tracked northeastward to the Blue Mountain Elementary School, then into a campground.

Nothing is popping just yet, but the government’s Storm Prediction Center, in Norman, Okla., has the entire region under a severe-thunderstorm watch until 11 p.m.

The storm center sees a 30 percent chance that storm winds would reach “severe” criteria – 58 m.p.h. or better. It also listed a 5 percent tornado probability.

It appears that the storms are going to hold off until after the peak commuting period, and that could lessen their intensities since that would be well after the peak heating period.

Those minute-by-minute forecast apps have become hot products in the weather marketplace, promising users exact starting and stopping times for precipitation for any location.

“It’s really been changing the way in which people consume weather,“ said Jon Porter, a meteorologist and vice president at AccuWeather, who helped develop the AccuWeather version.

After acquiring Canadian minute-caster Sky Motion in late 2013, AccuWeather entered the market in a huge way, expanding the service to 13 countries.

After a team surveyed the area, it determined that the top wind speed was 95 m.p.h. and that the twister had traveled about 1.5 miles.

The damage path was 100 yards wide, the weather service said.

In Paris Wednesday, tourists brought their own shade; temperatures crept toward 100.. (Associated Press)

Officially the temperature at London’s Heathrow Airport reached 98.1 Fahrenheit on Wednesday, a July record for the United Kingdom, according to the UK Met Office.

It fell short of the highest reading ever in the United Kingdom, according to UK Met’s Laura Young. That distinction belongs to the official site in Faversham, in Kent – 100.9, recorded in 2003.

She said official records date back over 100 years.

The 2014-15 fiscal year ended with quite a splash in parts of the region, including at Philadelphia International Airport.

By midnight, a total of 1.5 inches had fallen into the National Weather Service’s official rain gauge, boosting the monthly total to 8.88 inches and pushing June into an elite category for wetness.

Only two other years in the period of record, dating to 1872, were rainier: Two years ago, 10.36 inches cascaded in June, and in 1938, 10.06.

The National Weather Service has posted a flood watch for Philadelphia and Chester, Delaware and Montgomery Counties from noon Saturday until 5 a.m. Sunday.

As Glenn Schwartz has been telling us, heavy rains are likely on Saturday, and the weather service says the totals could be greater than 2 inches.

The weather service says that could cause the more-volatile streams to slosh over, and poor-drainage flooding is all but a given.

As Glenn Schwartz has just informed us, computer models are seeing 1 to 3 inches of rain for the weekend, with a decent slug of that late Saturday afternoon into Saturday night.

This has been quite a rainy month, starting with 2.26 inches on the first and second – that’s officially at Philadelphia International Airport.

And measureable rain has fallen on 13 of the first 24 days, and that could become 14 of the first 25 tonight.
