Missourians should prepare for dangerous heat as temperatures climb into the upper 90s and could reach the low 100s across the state through the Fourth of July.
National Weather Service meteorologist Brad Temeyer said heat index values are expected to approach 100 to 105 degrees each afternoon and evening, creating hazardous conditions for anyone spending extended time outdoors.
"We're looking at very, very warm temperatures continuing through the Fourth of July," Temeyer said. "The best thing to do is limit your outdoor exposure, especially during the peak heating of the day. Drink plenty of water, and if you can, take frequent breaks in air conditioning."
Temeyer said those without access to air conditioning should find a cool place to stay during the hottest parts of the day because overnight temperatures will provide little relief.
"If you're more susceptible to the heat, find areas with air conditioning and stay indoors as much as you can," Temeyer said. "We're just not going to see a lot of relief from the heat, even in the overnight hours. If you don't have air conditioning, it's important to find a place where you can cool off because this will be a prolonged heat event, and the cumulative effect can be significant."
Extreme heat is among the deadliest weather hazards in the United States, making it important for residents to stay hydrated, avoid strenuous outdoor activity during the hottest part of the day and check on vulnerable family members and neighbors.
