Dangerously Hot Temperatures Forecast

Much of the U.S. is set to experience dangerously high temperatures this week, with the Midwest and Northeast preparing for a significant heatwave. Health officials are urging residents to make safety plans now to mitigate the risks.

Southern States Already Affected

Over the weekend, the heatwave was already impacting Southern states. According to CBS News senior weather and climate producer David Parkinson, 22 million Americans will see temperatures of at least 100 degrees this week, 265 million will experience temperatures reaching 90 degrees, and 58 million are under heat advisories.

Heat Wave Impact

Last week, an early heatwave in the Southwest saw triple-digit temperatures in places like Phoenix, where temperatures reached 112 degrees on Saturday. This was significantly higher than the average of 105 degrees for this time of year, though still below the record highs.

Global Record-High Temperatures

This year has seen record-high temperatures globally, with over three-quarters of the world’s population experiencing at least one month of extreme heat.

U.S. Heat Wave Records

Last year, the U.S. experienced the highest number of heatwaves since 1936, with the South and Southwest being particularly affected, according to the National Oceanic and Atmospheric Administration.

Upcoming Heat Wave

The National Weather Service predicts the next heatwave will intensify on Sunday in the central U.S., spreading eastward. Some areas could see record-breaking temperatures throughout the week. A heat dome, where hot air is trapped by the atmosphere, is also expected in parts of the country.

Areas of Extreme Heat

The National Weather Service heat risk map indicates extreme heat from Texas to Maine. By Monday, this heat will move into the Great Lakes and Upper Ohio Valley regions, reaching the Northeast on Tuesday. Temperatures in the Mid-Atlantic and New England regions are expected to peak in the mid- to high-90s, with high humidity making it feel even hotter.

Potential Records in Ohio Valley and Northeast

Forecasters predict that the Ohio Valley and Northeast could set daily and monthly temperature records, with some areas feeling as hot as 105 degrees. Northern Maine might even reach 100 degrees, an unprecedented event.

Detroit’s Heat Wave

Detroit is expected to experience its worst heatwave in over 20 years, with temperatures forecasted in the mid-90s and heat indices around 100 degrees. This extreme heat could last into the weekend.

Dangers of Extreme Heat

Heat-related illnesses, such as heat exhaustion and heat stroke, can be deadly. Symptoms of heat exhaustion include heavy sweating, fatigue, and nausea, while heat stroke can cause confusion, dizziness, and a body temperature above 103 degrees. Immediate medical attention is crucial for heat stroke.

Long-term Impact of Climate Change

A National Institutes of Health-backed study projects an increase in heat-related deaths from 2036 to 2065 due to rising temperatures. Climate change will disproportionately affect vulnerable populations, exacerbating existing health disparities.

Staying Safe

Experts recommend staying indoors in air-conditioned spaces and limiting outdoor activities. If air conditioning is not available, find local cooling centers. Drink plenty of water, wear lightweight clothing, and check on vulnerable individuals, such as the elderly and those with chronic conditions.

Communities can prepare by opening cooling centers and providing resources like fans. Businesses with outdoor workers may adjust schedules to avoid peak heat times.


As the Northeast and Midwest prepare for an intense heatwave, it’s essential to take precautions and stay informed about the latest weather updates to ensure safety.
