Lawrence, in Douglas County, is facing an intense weather pattern this weekend, as the National Weather Service in Topeka has issued an extreme heat warning that will go into effect at noon on Saturday, July 19, and remain in place until 7 p.m. on Wednesday, July 23. The warning may be extended beyond this period if forecast conditions persist into next week.
Strong storms possible before the heat intensifies
Before the dangerous heat wave fully settles in, residents should also prepare for the possibility of strong to severe thunderstorms on Friday afternoon and evening, as well as during the day on Saturday. According to the NWS, the main threats from these storms include damaging wind gusts and brief but intense downpours. The atmospheric instability across northeastern Kansas is creating volatile conditions, which could escalate quickly, particularly during the late afternoon hours.
Dangerous heat index to reach 106° by Tuesday
As the weekend progresses, heat indices will likely soar to around 105°F (40.5°C) and could peak at 106°F (41.1°C) on Tuesday, July 22, in Lawrence. This level of heat stress poses a serious risk, especially to those who are outdoors for prolonged periods or without access to air conditioning.
Prolonged exposure can lead to heat-related illnesses
According to the NWS, during periods of extreme heat, car interiors can become lethal in just minutes, especially when the heat index climbs above the 90s°F. Fans may worsen the situation, rather than improve it, under these extreme conditions.
Heat exhaustion is a common early warning sign, with symptoms including heavy sweating, muscle cramps, weakness, clammy skin, dizziness, nausea, and a fast but weak pulse. A person experiencing these should be moved to a cooler location, have their clothing loosened, and be given small amounts of water.
More seriously, heat stroke is a medical emergency. Symptoms such as confusion, combativeness, seizures, slurred speech, a strong and rapid pulse, headaches, fainting, or nausea should prompt immediate action and a 911 call. Heat stroke can be fatal or lead to permanent damage in a short amount of time.
