Record May Heat Scorches the Mid-Atlantic as Storms Prepare to Sweep Across the Eastern United States

Oppressive heat settles over the East Coast

The heat settled over the eastern United States early and refused to let go.

By Wednesday afternoon, cities from Boston, MA to Raleigh, NC were sweltering under temperatures climbing well into the 90s. Pavement radiated heat back into the air. Subway stations felt stifling. Air conditioners rattled nonstop from apartment windows across entire neighborhoods.

For many people, it did not feel like late May.

It felt like the middle of summer.

Forecasters warned that highs would reach between 91 and 96 degrees across much of the mid-Atlantic and Northeast after several places recorded unusually high temperatures a day earlier.

In New Jersey, USA, the National Weather Service said temperatures hit 101 degrees on Tuesday.

“It is worth noting the all-time high for the month of May in New Jersey is 102 in Paterson on May 31, 1895," the agency posted on X.

The air felt thick and heavy in many cities. Sidewalk cafes emptied earlier than usual. Construction crews searched for shade during breaks. In parks and along crowded streets, people carried bottles of water and tried to avoid direct sun during the hottest hours of the afternoon.

New York City braces for storms after the heat

In New York, NY, heat advisories remained active across all five boroughs as officials urged residents to take precautions.

Mayor Zohran Mamdani encouraged people to stay hydrated, use cooling centers, and check on elderly neighbors and vulnerable residents as temperatures peaked during the afternoon.

“And please check in on your neighbors," Mamdani wrote on X.

But even while the heat remained intense, signs of change were already beginning to appear.

Clouds slowly started building above the skyline late in the day. The humidity deepened. The air became restless.

Forecasters said thunderstorms could begin arriving by late afternoon or evening as a cold front pushes toward the East Coast.

The cooldown behind the front is expected to be dramatic.

Temperatures in some locations could fall by more than 20 degrees by Thursday and Friday, bringing a sudden break from the oppressive heat that has gripped the region for days.

Rain may linger well beyond the initial storms, with forecasters warning that parts of the Northeast could face a wet Memorial Day weekend.

Severe storm threat stretches across multiple states

The approaching weather system is also creating conditions favorable for severe thunderstorms across a large section of the country.

The National Weather Service warned Wednesday of storm risks extending from the southern Plains into the Ohio Valley and parts of the lower Great Lakes.

In West Texas, USA, meteorologists warned that some storms could produce hail before the system shifts into south-central Texas later in the evening.

Warm, moisture-filled air continues flowing northward ahead of the front, helping fuel instability across several states.

Dark clouds are expected to build rapidly in some areas. Quick downpours, gusty winds, and dangerous lightning may develop as storms strengthen through the evening hours.

Some communities could see rapidly changing weather in only a matter of minutes.

Wildfires burn across California before peak fire season

On the opposite side of the country, firefighters in California are already battling multiple wildfires weeks before the traditional peak of fire season arrives.

Near Simi Valley, CA, the Sandy Fire had burned nearly 1,700 acres by Wednesday morning, according to the California Department of Forestry and Fire Protection. Officials said containment stood at 15%.

To the south, two more fires continued burning in Riverside County, CA near Los Angeles, CA.

The Bain Fire spread across roughly 1,375 acres and reached 25% containment, while the smaller Verona Fire remained below 500 acres.

Smoke drifted across parts of Southern California throughout the day, leaving hazy skies over several communities.

The South Coast Air Quality Management District issued a smoke alert for Riverside County, San Bernardino County, and Los Angeles County, warning residents about deteriorating air quality.

Officials urged people to:

• Remain indoors with windows closed
• Use air purifiers if available
• Limit exposure to smoky conditions
• Avoid strenuous outdoor activity

“Depending on fire activity, smoke conditions are expected to improve during the day in areas not adjacent to active fires," the agency said.

In some areas, the smell of smoke drifted through neighborhoods long before flames became visible. Helicopters circled repeatedly overhead while dry hillsides glowed brown beneath the afternoon sun.
