The affected regions include the lower Great Lakes, mid-Atlantic, Mississippi River Valley, Ohio River Valley, eastern Plains, and parts of the Southeast. Major cities such as New York City, Philadelphia, Washington D.C., Baltimore, Chicago, Indianapolis, St. Louis, Detroit, Dallas, Little Rock (Ark.), Memphis (Tenn.) and Pittsburgh are expected to experience high temperatures.
As of Thursday morning, extreme heat warnings affect more than 102 million people nationwide with another 43 million under extreme heat watches. This includes a broad swath of the Midwest, Ohio Valley, Northeast, and parts of Minnesota, Kansas, Tennessee, and Pennsylvania. The NWS estimates that temperatures will reach between 100 to 105°F in some areas by Thursday and Friday as the heat wave peaks.
Most of Georgia is under a heat advisory from noon through 8 p.m. on Monday. While the actual high temperature will be 96 degrees in Atlanta, the humidity will make it feel much hotter with heat indices between 105 and 110 degrees or higher. The NWS recommends staying hydrated, wearing lightweight clothing, and limiting strenuous activities to early morning or evening hours.
The prolonged high temperatures are driven by a 'heat dome,' a high-pressure area in the atmosphere that traps hot ocean air. This weather pattern can last for days or weeks and typically affects large areas. The heat wave has already forced summer camps and other outdoor activities in the Midwest to be canceled, according to the Associated Press.
The NWS has issued extreme heat warnings for parts of Illinois, Iowa, Kansas, Michigan, Tennessee, New York City and Washington D.C. Experts warn that extreme heat is the deadliest form of extreme weather in the U.S., killing more people annually than any other weather hazard including hurricanes or tornadoes. Health officials advise residents to stay hydrated, use cooling systems, and avoid prolonged outdoor activities during peak temperatures.
The Pittsburgh area is also bracing for extremely hot conditions this week. Even though triple-digit temperatures are not forecasted the heat index will flirt with triple digits due to high humidity levels. The NWS issued a heat advisory from 11 a.m. on Tuesday until 10 p.m. on Friday for northwest, southwest and western Pennsylvania.
High temperatures in Pittsburgh are expected to reach the low to mid-90s, with low temperatures only dropping into the 70s. This limited cooling period means heat will build up in homes and other structures. The NWS predicts that dangerous heat will peak on Wednesday and Thursday continuing through the Fourth of July weekend.
Storms are expected to move into the Pittsburgh area this weekend, potentially disrupting Fourth of July plans but also breaking the heat wave.
