BRACE YOURSELVES! A 'Heat Dome' is Bringing DANGEROUS Temperatures to the US!

A major heatwave is set to engulf the United States this week, bringing dangerously high temperatures and humidity to millions. The Midwest, particularly Nebraska, Illinois, Wisconsin, and Iowa, will be hardest hit this weekend, with forecasters warning of extreme temperature impacts. This marks the arrival of true summer weather for many across the region and the East Coast. The humidity will make temperatures exceeding 90°F (30°C) feel up to 20 degrees hotter. A heat dome, a high-pressure system trapping heat and humidity, is the culprit. Daytime temperatures in the 90s°F (30s°C) and overnight lows in the mid-70s°F (mid-20s°C) are expected from the Great Lakes to the East Coast, lasting into next week. Moisture from the Gulf of Mexico is fueling the muggy conditions. The heat will be widespread, with Denver potentially reaching 100°F (38°C) on Friday, Chicago 96°F (36°C) on Sunday, and Washington, D.C., and New York City reaching near 100°F (37°C) by Tuesday. Several Midwest states face the highest risk levels for dangerous heat, particularly Nebraska and Kansas on Saturday, and Iowa, Wisconsin, Missouri, and Illinois on Sunday. High humidity hinders the body's ability to cool down through sweating, increasing the risk of heatstroke. The article advises minimizing sun exposure, wearing light clothing, staying hydrated, and seeking air-conditioned spaces to mitigate the risks. The difference between humid and dry heat is explained, with the latter being less dangerous due to faster sweat evaporation. Even crops contribute to humidity, a phenomenon known as "corn sweat", though this is less significant than the moisture from the Gulf.
