Fireworks and frankfurters won’t be the only things sizzling this Fourth of July week. People living in much of the Northeast and part of the Southeast will experience very hot days, with record-high temperatures in some places, according to a story in USA Today. Temperatures will soar into the 90s to near 100 degrees in the Northeast over the next couple of days, some 10 to 20 degrees above average, says the National Weather Service.
This past Sunday saw record high temperatures in Keene, New Hampshire (102 degrees), and Allentown, Pennsylvania (98 degrees), and the forecast calls for more of the same. Punishing humidity levels will push the heat index, which takes into account both air temperature and humidity, as high as 110 degrees in many areas.
"I know not everyone can stay inside, but if you have to be outside, please bring water and hydrate," said Mike Evans, a National Weather Service meteorologist in Albany, New York.
Heat advisories and excessive heat warnings are in effect from North Carolina to New Hampshire. Air pollution concentrations will reach unhealthy levels for sensitive individuals in many areas. The weather service warns that overnight lows will also be quite sultry, especially in urban areas where readings could remain above 75 degrees all night. AccuWeather meteorologist Alex Sosnowski said "the vast expanse of concrete, pavement and brick will give off heat through the night."
On the Fourth of July of itself, Wednesday, hot, humid weather will continue over most of the eastern half of the country. Scattered thunderstorms are expected over much of the Southeast, particularly from the Texas coast to Florida and the Carolinas, weather.com reported.
The U.S. Centers for Disease Control and Prevention reminds everyone that heat is one of the most dangerous weather hazards. Around 150 to 300 people are killed directly by heat in the U.S. each year, and in some years, it contributes to hundreds more deaths. Landscapers and other people who work outdoors should take extra precautions against heatstroke, sunburn and dehydration.
Never leave children or pets in hot automobiles, even for one minute. On a 90-degree day, the inside of a car can heat to 120 degrees in as little as 15 minutes, according to Golden Gate Weather Services. This year, 18 children in the U.S. have died so far after being locked or forgotten in a hot car.
