by Dangerous heat reaches today in the Central-United States, since a heat dome in the hottest month of summer is directed to its reputation-but the sauna-like conditions only begin to the east.
The heat index – how hot it actually feels in view of the temperature and moisture – will increase over 110 degrees from the golf coast to the middle west on Thursday afternoon in the 100s.
Memphis, Tennessee, had its hottest day of the year on Wednesday with a high of 97 degrees and a heat index of at least 106 degrees. The city could match this intensive heat on Thursday, while the heat index in Greenville, Mississippi, in Süd -Mississippi, could reach 110 degrees. Further north, Chicago’s high temperature of 94 degrees could come within a certain degree of his hottest day this year.
The same roasting summer heat crept into the middle Atlantic and northeast on Thursday. The high temperatures in the 90s are probably about 30 miles from the Canadian border on Thursday afternoon to Burlington, Vermont.
The worst warmth for the east arrives on Friday with high temperatures in the middle to upper 90, which is expected from Washington, DC to Boston. These temperatures are up to 10 degrees higher than the typical hottest conditions for this season and could question the high -temperature record for the day in Baltimore, Philadelphia and New York City.
The heat index reached or exceeded 100 degrees for many large metros: Washington, DC and Philadelphia will feel more like 105 degrees on Friday afternoon and Baltimore will feel almost 110 degrees at times.
Heat remains the most fatal form of extreme weather in the USA. Heat waves worldwide become more often, more serious and last longer because the world warms up climate change due to the fossil fuel stall.
More than 60 million people in the eastern half of the United States are at least one level 3 of 4 “main heating risks” on Thursday. According to the National Weather Service, the total amount has risen to more than 90 million on Friday.
Heat these serious effects on any non -effective cooling or proper fluid intake, not only population groups in need of protection, according to the National Oceanic and Atmospheric Administration. And for those without air conditioning it can remain fatal in the hottest parts of the day, warns the agency.
Moist conditions also prevent the temperatures from cooling down significantly overnight. It could still be almost 80 degrees in Washington, DC, from sunrise on Saturday – almost 10 degrees higher than a typical low point at the end of July.
If the overnight temperatures do not cool enough to offer relief in overheated bodies, people have a higher risk of heat -related diseases. The nightly temperatures take the toughest hits from climate change and warm up faster than the daily highs.
Climate change makes the heat wave this week for almost 160 million people, almost half of the US population, compared to a world without emissions of fossil fuels, at least three times more likely, as can be seen from the Climate Research Non -Profit Climate Central.
The heat dome shrinks Saturday, replaced by typical, albeit still very toastic conditions, the parts of the northeast and the middle west are still very toasty. The sultry heat remains at the weekend, mainly in southern parts of Ohio Valley and on Saturday and in parts of Southeast Sunday.
According to the latest forecasts of the Climate Prediction Center, this general trend of a hotter than normal south will continue to be continued until next week.
