This early heat wave follows a severe heat wave that impacted the western United States just weeks ago, indicating it’s the East’s turn now.

Approximately 135 million residents in the Midwest could feel temperatures soaring at least 15 degrees above average on Tuesday. Many locations, including Ohio, Missouri, Illinois, Tennessee, Georgia, North Carolina, Virginia, Pennsylvania, New York, Connecticut, and Washington, D.C., are forecasted to experience temperatures exceeding 80 degrees Fahrenheit.

As temperatures escalate midweek, summer-like conditions are anticipated, climbing into the 90s in the mid-Atlantic region, according to the National Weather Service.

Meteorologists predict over 100 record high temperatures may be shattered this week, including possible April highs.

For instance, St. Louis might see highs of 90 degrees, while Memphis, Tennessee, could hit 87 degrees. Richmond, Virginia, is expected to rise to 91 degrees, with temperatures potentially reaching 94 midweek.

In the Northeast, summer temperatures may become common this April, with Philadelphia expecting 87 degrees on Tuesday and 91 later in the week. New York City is projected to hit 85 on Tuesday, increasing to 87 by Thursday. Washington, D.C., is forecasted for 89 degrees on Tuesday, followed by highs of 92 on Wednesday and Thursday.

The current heatwave is attributed to a significant ridge of high pressure, which is effectively trapping warm air across the eastern part of the country, much like a lid covers a pot, enhancing the heat.

Last month, California and the desert Southwest shattered over 150 daily temperature records and around 50 monthly all-time records, with temperatures soaring 20 to 40 degrees above normal for over a week.

Several cities in California and Arizona recorded temperatures in triple digits.

The National Oceanic and Atmospheric Administration reported that March was the hottest on record in the United States, with an average temperature of 50.85 degrees—9.35 degrees higher than the 20th-century March average based on 132 years of federal data.

While connecting specific weather events to climate change can be complex, it is understood that global warming contributes to more frequent, intense, and longer-lasting heat waves.

Heat waves are particularly perilous, causing more annual fatalities in the U.S. than hurricanes, floods, and tornadoes combined. Early-arriving heat waves pose additional risks as people’s bodies may not be acclimated yet.
