For Eastern US, temperatures swing high, then swing low. They’ll soon go back up

After days of puffy heat, the nation’s sweat coast opened its windows, coming out and relieving itself temporary on Friday while temperatures fell up to 40 degrees and the humidity fell next to it.

At least 68 record summits have been fixed and more than 20 places recorded three -digit heat from Sunday to Wednesday before a cold northern front heard a heat dome grip in the region on Friday. Boston, who reached a record of 102 Fahrenheit (around 39 Celsius) on Tuesday, was 61 years (around 16 Celsius) on Friday.

This cool comfort explosion has resulted in temperatures up to 10 to 15 degrees below normal, but was not close to cold records, said Frank Pereira, meteorologist at the National Weather Service.

The only place that could break a cool record of any type on Friday is a small philadelphia station at the Franklin Institute, where the lowest recorded top for the day is 75 (around 24 Celsius). It was expected that he could only reach 72 (about 22 Celsius), said Pereira. But the files do not go back very far on this site and the meteorologists of Philadelphia do not consider it as representative of the region, which is unlikely to obtain a record for cool, said meteorologist Ray Martin in the local office of weather forecasts in Mount Holly, New Jersey.

This is so revealing on this cervical boost from hot to cool and soon to be turned over – the central meteorologist of the Bernadette Woods Placky climate.

“We have had so many record heights, not only our maximum daytime temperatures, but our low night temperatures in a widespread region of the country, so this massive change feels good and that gives everyone a break, which is good,” said Woods Placky. “But that does not necessarily come with low records on the other side.”

This is a signature of climate change caused by humans compared to the combustion of fossil fuels, she said: “We get more records than that does not have the impression that it is a big news because it happens so often. But we do not get as much record so often.”

The central climate record record show 68 brands at high temperature since Sunday and only three bass: Billings, Montana; Casper, Wyoming; And Jackson, Idaho – All recorded on Sunday.

During the first five months of this year, there were almost twice as many high daily records – 14,863 – in the United States as low records – 7,855 – according to recordings compiled by meteorologist Guy Walton, who follows NWS Records. For the 2020s as a whole, it is much higher than double with 221,971 sets of high daily records and 93,429 sets of daily records.

With the exception of the Dust Bowl era – which the ratio of the ups at the bottom is still not close to the doubling – the number of ups and downs every day and the stockings were between the 1920s in the 1920s, but since then, the Record heat report has taken off.

This oriental cooling will not last, said Pereira of the meteorological service. Soon the heat will be back and the temperatures to the east will be again above normal, even for the summer.

But, he said, “we don’t look at temperatures as oppressive as before in the week.”

The cervical boost from one extreme to another is often a sign of climate change of human origin because the stream jet – the high air river above us which moves the meteorological systems generally from the east – weakens, weakens and gets stuck more because of global warming, have declared the woods and other scientists.

When this happens, it means more extremes such as heat wave or drought or showers. And then when the stuck jet flow moves, it sometimes translates into extreme opposite time.
