According to the NWS, temperatures are expected to soar to 32 degrees Celsius (90 degrees Fahrenheit) or higher for at least a week, with the blistering conditions possibly extending until June 26.
“The first heat wave of the summer begins Sunday over the middle of the nation, before spreading to the Midwest and to the Northeast by Tuesday, then lasting most of next week,” the weather office stated.
In some regions, temperatures could climb to a scorching 40.56°C (105°F), setting new records and resulting in unusually warm nights.
Major metropolitan areas such as Chicago, Indianapolis, Cleveland, Pittsburgh, Philadelphia, and Boston are bracing for their hottest days of the year, compounded by high humidity levels that will exacerbate the discomfort.
The southeastern U.S. has been enduring a heat dome phenomenon, where high-pressure systems trap hot air, preventing cooler air from moving in and inhibiting cloud formation. This weather pattern has led to stifling conditions, with little respite in sight.
As the heat wave advances, officials are urging residents to take precautions against heat-related illnesses, stay hydrated, and limit outdoor activities during peak heat hours.
The NWS is closely monitoring the situation and will provide updates and advisories as the heat wave progresses.
