As summer begins, a map of the US reveals the presence of a heat dome stretching across the eastern part of the country. This dome, which represents varying levels of heat risk from minor to extreme, has already begun to blanket the nation and is set to unleash scorching temperatures across more than 30 states. In fact, some areas may even break records that have stood for centuries.
This heat dome wasted no time in making its grand debut, making its presence known on the first day of summer. And unfortunately, it shows no signs of leaving anytime soon. In fact, it is predicted to linger well into next week, subjecting much of the nation to its stifling effects. In total, over 100 million Americans have been issued heat warnings, spanning from the Northeast all the way to the Central Plains.
You may be wondering, what exactly is a heat dome? Well, it is essentially a high-pressure system that traps hot air and simultaneously blocks cool air from entering. As a result, it causes prolonged heat waves that can be dangerous and uncomfortable for those living within its reach. But where exactly is this heat dome located within the US?
According to the National Weather Service, on Friday, temperatures in central states such as Illinois, Colorado, Kansas, Iowa, Missouri, and Nebraska soared into the upper 90s and even reached the lower 100s. And unfortunately, this weekend, the heat dome is expected to continue its journey eastward, bringing intense heat to the Ohio Valley, mid-Atlantic region, and the Northeast.
For instance, on Saturday, the forecast in New York City predicts temperatures in the low 90s, while on Sunday, Boston and Philadelphia are expected to hit the mid-90s. As this heat dome continues to move, it is crucial for people to take necessary precautions and stay cool to avoid any heat-related illnesses. Stay safe and stay cool, everyone.
