Extreme heat is spreading into the Midwest while much of the East Coast continues to experience hot and humid conditions. Weather coverage describes a broad summer pattern marked by high temperatures, elevated humidity and hazy conditions, with little relief overnight in some areas.
The heat is also contributing to concerns about wildfires and potentially severe storms across parts of the country. The combination of dry conditions in some regions and unstable, storm-producing air in others is creating a varied set of weather risks as the hot pattern persists.
Forecasts indicate that some locations could see temperatures approach or exceed 100 degrees, while nighttime temperatures remain unusually warm, in some cases near 90. Such limited overnight cooling can make it more difficult for people and communities to recover from prolonged daytime heat.
Monsoon rains may provide relief in parts of the desert Southwest, although rainfall and its effects are expected to vary by location. Forecasters continue to monitor the changing heat, humidity, storm and wildfire conditions across the country.
