When will it end? Latest heat wave forecast.
It all depends on location, forecasters said, with some seeing cooling as early as Tuesday. But more relief is coming later in the week.
The brutal late-June heat wave that's scorching tens of millions of people stretches from the Midwest to the Northeast and is causing sweltering folks to wonder when it will finally end.
It all depends on location, forecasters said, with some seeing relief as early as Tuesday, June 24, while others may not see any cooling temperatures until later in the week.
In some spots, the extreme heat is expected to last through much of this week, the weather service said June 23. The most significant heat impacts are anticipated across the Mid-Atlantic through Thursday, June 26 and the eastern Ohio Valley into Friday, June 27, "leading to several consecutive days of oppressive heat."
The longest duration of well above-average temperatures will be centered over the eastern Ohio Valley into Friday June 27, the weather service said.
When will the heat wave break?
June 24 will be the peak of the heat wave in the Northeast. But Weather.com meteorologist Jonathan Erdman says some will soon feel relief:
- June 24: Iowa, Wisconsin and northern Michigan
- June 25: Rest of the Great Lakes, and northern New England
- June 26: Most of the Northeast, including Boston and New York City
Thunderstorms to provide some relief
According to AccuWeather, cooling thunderstorms will offer brief reprieves from the heat, but not the humidity, in some areas this week. "In addition to gusty storms on the periphery of the heat dome from the Plains to New England, pop-up thunderstorms can bubble up and fizzle out in a random nature, especially across the South," said AccuWeather meteorologist Bill Deger.
"A more significant intrusion of thunderstorm activity is expected to unfold along a battle zone on the heat dome's northeastern periphery from the Great Lakes to the Northeast and northern mid-Atlantic beginning Wednesday (June 25)," Deger said.
He added that with more cloudiness and rain in the forecast then, temperatures will come down from their early week peaks, but still likely run well into the 90s for most in the mid-Atlantic.
Still summerlike even after the heat wave breaks
In the Mid-Atlantic and Appalachians, the worst of the heat will last through June 25 or 26, "with some relief dropping temperatures a bit late this week into the weekend, although it will still feel plenty like summer," Erdman said.
In the Mid-Mississippi and Ohio Valleys, Erdman said it will remain uncomfortably hot and humid much of the week.
