OKLAHOMA CITY — Record-setting heat is expected to expand across parts of the U.S. Plains as forecasters warn of dangerous temperatures and the potential for severe thunderstorms in portions of the region, increasing risks for heat-related illness and weather-related hazards.
The National Oceanic and Atmospheric Administration’s Climate Prediction Center said an elevated risk of extreme heat is forecast across the Great Plains and other parts of the central United States during mid-July as a strong area of high pressure builds over the region. The agency said some areas could experience temperatures well above average, with heat index values in humid areas potentially exceeding 105 degrees Fahrenheit.
The National Weather Service has urged residents in affected areas to take precautions during periods of extreme heat, including limiting strenuous outdoor activity, seeking air-conditioned environments when possible, and staying hydrated. The agency has identified high temperatures combined with humidity as a significant factor in increasing the risk of heat-related health impacts.
Forecasters are also monitoring storm development along weather boundaries stretching across parts of the Plains. The Weather Prediction Center said strong to severe thunderstorms were possible across portions of the Northern and Central Plains, with hazards including damaging winds and large hail.
The combination of intense heat and storm activity reflects a pattern of competing weather hazards across the region, where high temperatures can persist while atmospheric conditions support thunderstorm development. The Weather Prediction Center said severe storm threats were expected to shift across parts of the Plains and Midwest as weather systems move through the area.
Health officials typically warn that prolonged heat exposure can increase the likelihood of heat exhaustion and heat stroke, particularly among older adults, young children, outdoor workers, and people with underlying health risks. The National Weather Service’s HeatRisk guidance provides information on expected heat impacts and recommended safety measures.
The Climate Prediction Center said the broader heat risk could continue into mid-July, with forecasts indicating above-normal temperatures across parts of the western, central and southeastern United States. Officials said forecasts would continue to be updated as conditions evolve.
Meteorologists are expected to continue monitoring temperature trends and thunderstorm potential across the Plains, with additional forecasts and local alerts to be issued by the National Weather Service as needed.
