New York City, New York — A powerful surge of heat and humidity is expected to impact more than 100 million people across the East Coast later this week, with forecasters warning that some cities could experience their hottest temperatures of the year so far.
Meteorologists say the combination of soaring temperatures and oppressive humidity could create dangerous conditions from the Mid-Atlantic through New England.
Major Heat Wave Expands Across East Coast
According to forecasters, the heat surge will develop as a strong area of low pressure moves through central and southern Canada while high pressure remains anchored off the East Coast.
This weather pattern is expected to generate strong southerly winds capable of transporting hot, humid air northward along much of the Interstate 95 corridor.
Beginning Thursday, a very moist air mass is forecast to spread into the Mid-Atlantic and Northeast.
Meteorologists expect dew points, which help determine how humid the air feels, to rise dramatically from the 50s into the upper 60s and low 70s.
The result will be a much more uncomfortable environment across densely populated urban areas.
Temperatures Could Reach Mid- to Upper 90s
Forecasters say actual air temperatures will climb well above seasonal averages.
Many communities from Richmond, Virginia, through Washington, D.C., Philadelphia, and into New York City are expected to see temperatures rise into the mid-to-upper 90s by Thursday and Friday afternoon.
Those readings are approximately 10 to 15 degrees above normal for mid-June. Because of the high humidity levels, conditions may feel even hotter than the actual temperature.
Experts warn that heat index values could climb into the triple digits, increasing the risk of heat-related illnesses.

Record Temperatures May Fall
The unusual June heat could challenge or break dozens of long-standing temperature records. Forecasters say more than 40 daily record highs could potentially be broken on Friday alone.
Cities such as Washington, D.C. and Philadelphia are among the locations most likely to challenge existing records. These cities could also experience their hottest temperatures recorded so far this year.
For residents of New York City, a forecast high of 95 degrees on Thursday would mark the city’s warmest day since July 30 of last year.
Heat Advisories Possible
As temperatures and humidity continue to increase, weather officials may issue additional alerts.
Forecasters say Heat Advisories or even Extreme Heat Watches could become necessary if current projections remain unchanged.
Health experts often urge people to stay hydrated, avoid strenuous outdoor activities during peak afternoon hours and check on vulnerable family members during periods of extreme heat.
Older adults, young children and individuals with underlying medical conditions are typically most at risk during prolonged heat events.
Above-Average Temperatures Expected to Continue
The upcoming heat wave may not be a short-lived event. Long-range outlooks suggest warmer-than-normal temperatures could continue throughout much of June.
The Climate Prediction Center’s eight-to-14-day outlook indicates that above-average temperatures are likely across virtually the entire East Coast.
That means residents may need to prepare for additional stretches of summer-like heat even after this week’s surge begins to ease.
With millions expected to experience dangerous heat conditions, officials are encouraging people to monitor local forecasts and take precautions as temperatures continue to climb.
