College Park, Maryland – A sprawling heat wave is set to intensify across the western and central United States this weekend before expanding into the central U.S. and Gulf Coast early next week, bringing several days of dangerous temperatures and increasing the risk of heat-related illness.
According to the NOAA Weather Prediction Center, dangerous heat will build from Friday through the weekend across much of the West and central United States before spreading farther east early next week. Afternoon highs are expected to reach the 90s to well above 100 degrees, while overnight temperatures remain unusually warm, limiting relief after sunset. Across portions of the Desert Southwest, temperatures could climb as high as 115 degrees, with heat index values reaching 105 to 115 degrees in some areas.
The highest risk for extreme heat stretches from parts of the Southwest into the central Plains and lower Mississippi Valley, where repeated days of intense heat can place added stress on people without reliable cooling. Major metropolitan areas from Phoenix and Las Vegas to Oklahoma City, Dallas, Kansas City, St. Louis and Memphis could experience prolonged periods of dangerous heat through early next week.
Forecasters also warn that persistent hot and dry conditions are increasing the potential for rapid-onset drought across portions of the central United States. Continued heat combined with limited rainfall and increased evaporation may quickly worsen drought conditions in affected regions.
Residents should limit strenuous outdoor activities during the hottest part of the day, drink plenty of water, wear lightweight clothing and seek air-conditioned spaces whenever possible. Check on older adults, young children and neighbors who may be more vulnerable to heat-related illness, and ensure pets have access to shade and fresh water.
The Weather Prediction Center expects the heat wave to remain a significant concern through at least the middle of next week, with additional heat advisories, watches and warnings likely as the event expands across more of the country.
