Residents of Lawrence and Douglas County in northeastern Kansas are bracing for a period of extreme heat, as an Extreme Heat Warning is set to take effect. The warning, issued by the National Weather Service (NWS) in Topeka, will begin at noon on Saturday, July 19, 2025, and is expected to continue through 7 p.m. on Wednesday, July 23, 2025. Forecasters indicate that this warning could be extended further into next week if current predictions hold true, with heat indices likely to hover around 105°F and potentially peaking at 106°F on Tuesday. In addition to the heat, strong to severe storms are also possible on Friday afternoon and evening, and again on Saturday, bringing risks of damaging wind gusts and brief heavy rainfall, according to The Lawrence Times.
An Extreme Heat Warning signifies extremely dangerous heat conditions are either expected or already occurring. The National Weather Service typically issues such a warning when the heat index is anticipated to reach at least 105°F for more than three hours per day for two consecutive days, or if it exceeds 115°F for any duration. This alert level was updated from the previous “Excessive Heat Warning” on March 10, 2025, following a public survey in 2018, as detailed by Wikipedia and Weather.gov. Other heat-related alerts include a Heat Advisory, issued for dangerous heat conditions that do not meet warning criteria (e.g., 100-104°F heat index for at least two days), and an Extreme Heat Watch, indicating favorable conditions for an extreme heat event within 24 to 72 hours.
Extreme heat poses significant health risks, including heat exhaustion, heat stroke, and dehydration. Heat stroke, the most severe heat-related illness, can quickly lead to death or permanent disabilities. Symptoms of heat exhaustion include heavy sweating, weakness, clammy skin, a fast and weak pulse, muscle cramps, dizziness, and nausea. If these signs appear, individuals should move to a cooler environment, loosen their clothing, and sip water. Conversely, heat stroke symptoms are more severe, characterized by confusion, combativeness, seizures, slurred speech, headaches, a strong and rapid pulse, fainting, and an extremely high body temperature (above 103°F) with hot, red, and dry skin (or sometimes damp skin). In cases of suspected heat stroke, it is crucial to call 911 immediately and move the person to a cooler, shaded area while attempting to cool them down with cold wet cloths or ice packs on the head, neck, armpits, and groin. Do not give them anything to drink. It’s also important to note that using a fan when heat index temperatures are above 90°F may actually make a person hotter, as fans create airflow but do not reduce body temperature, according to the NWS and Ready.gov.
To stay safe during this period of extreme heat, authorities urge the public to take several precautions. These include staying indoors in air-conditioned spaces as much as possible, especially during the hottest parts of the day. If outdoor activities are unavoidable, schedule them for the early morning or evening hours. Wear lightweight, loose-fitting, and light-colored clothing. Hydration is key; drink plenty of fluids, even if you don’t feel thirsty, and avoid alcohol. Never leave people or pets unattended in vehicles, as car interiors can reach lethal temperatures within minutes. Vulnerable populations, such as older adults, young children, individuals with chronic medical conditions, and outdoor workers, are at higher risk and should be checked on regularly. Many communities offer cooling centers, such as libraries, shopping malls, and community centers, as public refuges from the heat. Residents are encouraged to identify such locations in their area and utilize them if their homes lack adequate air conditioning.
