Record-Breaking Heat Wave Subsides Across midwest and Eastern US
After a week of sweltering conditions, a record-breaking heat wave that impacted the Midwest and eastern United States is beginning to subside, the National Oceanic and Atmospheric Management (NOAA) reported on June 26, 2025. While the worst appears to be over, heat advisories remain in effect for several regions.
Heat Dome Responsible for Extreme Temperatures
The intense heat was fueled by a “heat dome,” a persistent high-pressure system that traps heat close to the ground. this phenomenon forces the jet stream northward, acting like a lid on a pot and preventing cooler air from entering the affected areas. Such heat waves can persist for days or even weeks.
did You Know? The summer of 1936 saw some of the highest temperatures ever recorded in the United States, with many states experiencing temperatures exceeding 110°F. NOAA provides past context on notable heat waves.
Affected Regions and Current Advisories
As of June 26, 2025, heat advisories still covered significant portions of the Ohio and Tennessee Valleys, as well as the Middle and Lower Mississippi Valley. Residents in these areas are urged to take precautions to avoid heat-related illnesses.
NOAA Monitoring and Forecasting
NOAA scientists have been closely monitoring the heat wave using the Global Forecast System (GFS) model. This model incorporates data from the Joint Polar Satellite System (JPSS) satellites, a collaborative effort with NASA, to provide accurate short and long-term weather forecasts.
Pro Tip: Stay hydrated by drinking plenty of water, even if you don’t feel thirsty. Avoid strenuous activities during the hottest parts of the day.
Understanding the Joint Polar Satellite System (JPSS)
The Joint Polar Satellite system (JPSS) represents a significant advancement in weather observation technology. This system provides critical data for severe weather prediction and environmental monitoring, improving the accuracy of forecasts three to seven days in advance of major weather events.

Protect Yourself from the Heat
It’s crucial to recognize the signs and symptoms of heat exhaustion and heat stroke.The NWS Heat Safety Website provides valuable preparedness information to help you stay safe during periods of extreme heat.
The Science of heat Waves
Heat waves are prolonged periods of abnormally hot weather, typically lasting several days to weeks. They can occur due to various factors, including atmospheric patterns, climate change, and local weather conditions. Understanding the causes and impacts of heat waves is crucial for developing effective mitigation and adaptation strategies.
