‘Heat dome’ to bring near-record warmth
Summerlike warmth will surge back across the Midwest and Northeast during the first week of October as high temperatures soar well into the 80s.
Some record-high temperatures may be challenged, AccuWeather said. High temperatures should be up to 20 degrees above average from the mid-Mississippi Valley into the Great Lakes and the interior Northeast.
That warmth will spread to much of the East Coast later in the week
The warmth will be courtesy of a “heat dome,” which features a sprawling area of high pressure about 20,000 feet high in the atmosphere, according to the Capital Weather Gang. Under the dome, air sinks, gets compressed and, ultimately, warms the ground.
Guy Walton, a former Weather Channel meteorologist, called the weather pattern “warm, weird and spooky.”
Fortunately, when compared with the heat wave from late September, this one should not be as hot because the sun’s intensity continues to decrease as it sinks lower in the sky each day.
