Kansas City, Missouri – Millions of people across the Midwest are facing another day of dangerous, potentially life-threatening heat as a sprawling dome of high pressure locks much of the nation’s heartland under Extreme Heat Warnings. Heat indices between 105 and 115 degrees are expected across portions of the Plains, Missouri Valley and Upper Midwest, while overnight temperatures remain unusually warm, offering little relief.
According to the National Weather Service, a persistent upper-level ridge centered over the central and southern United States will continue producing widespread Major HeatRisk, with isolated areas reaching Extreme HeatRisk through Monday. Afternoon highs will climb into the upper 90s and lower 100s across much of the region, while high humidity pushes feels-like temperatures well into the triple digits.
The greatest concentration of warnings stretches from Kansas, Nebraska, Iowa and Missouri into South Dakota, Minnesota, Wisconsin and Illinois, where numerous National Weather Service offices have issued or extended Extreme Heat Warnings. Parts of eastern Nebraska and western Iowa could experience heat indices as high as 116 degrees, while communities around Kansas City, Des Moines, Omaha, Sioux Falls, Minneapolis, St. Louis and Springfield remain under dangerous heat alerts through at least Monday, with some extending into Tuesday.
The prolonged nature of this heat wave is increasing the risk of heat-related illness because overnight lows will only fall into the 70s in many locations. Without adequate cooling and hydration, the body has little opportunity to recover before another day of extreme temperatures.
Officials urge residents to avoid strenuous outdoor activity during the hottest part of the day, drink water frequently, check on older adults and neighbors, and never leave children or pets inside parked vehicles, where temperatures can become deadly within minutes. Outdoor workers should schedule frequent breaks in shaded or air-conditioned locations.
Forecast confidence remains high that dangerous heat will continue across much of the Midwest through Monday before conditions gradually begin to ease in some areas early this week. Additional heat warnings and advisories remain possible as the event continues.
