Extreme Heat Warning Issued for Twin Cities Metro Through Early Monday; Heat Index Could Reach Over 100 Degrees
Published: July 24, 2026
TWIN CITIES, MINNESOTA: Residents across the Twin Cities metro, including Dakota County and surrounding communities, are being urged to take precautions this weekend as dangerously hot and humid conditions are expected to settle into the region.
The National Weather Service has issued an Extreme Heat Warning that will be in effect from noon Saturday through 6 a.m. Monday, covering Anoka, Carver, Dakota, Hennepin, Ramsey, Scott, and Washington counties.
Forecasters say temperatures combined with high humidity will push heat index values as high as 102 degrees, creating dangerous conditions for anyone spending extended periods outdoors. Even overnight, temperatures are expected to provide little relief, with lows remaining in the mid-70s.
Dangerous Heat Can Become Life-Threatening
The National Weather Service warns that prolonged exposure to extreme heat can quickly lead to heat-related illnesses, particularly for older adults, young children, individuals with chronic health conditions, outdoor workers, and those without access to air conditioning.
High humidity reduces the body's ability to cool itself through sweating, making it feel significantly hotter than the actual air temperature.
Safety Tips
Officials encourage everyone to take the following precautions during the warning period:
Drink plenty of water, even if you do not feel thirsty.
Spend as much time as possible in air-conditioned buildings.
Avoid prolonged exposure to direct sunlight.
Limit strenuous outdoor activities to the early morning or late evening.
Wear lightweight, loose-fitting, and light-colored clothing.
Check on elderly relatives, neighbors, and anyone who may be vulnerable to the heat.
Never leave children or pets unattended inside a vehicle, even for a short time. Vehicle interiors can reach deadly temperatures within minutes.
Know the Warning Signs
Residents should also be aware of the symptoms of heat-related illnesses.
Heat exhaustion may include:
Heavy sweating
Weakness or fatigue
Dizziness
Nausea or vomiting
Cool, pale, clammy skin
Muscle cramps
If someone is experiencing heat exhaustion, move them to a cooler location, provide water if they are conscious, and seek medical attention if symptoms worsen or do not improve.
Heat stroke is a medical emergency and can include:
Body temperature above 103 degrees
Hot, red, dry or damp skin
Confusion
Slurred speech
Loss of consciousness
Seizures
Anyone showing signs of heat stroke should receive immediate medical attention by calling 911.
Plan Ahead
With the warning remaining in effect through early Monday morning, residents planning outdoor events, sporting activities, festivals, or yard work should consider adjusting schedules to avoid the hottest part of the day.
Officials emphasize that taking simple precautions can significantly reduce the risk of heat-related illness during what is expected to be one of the hottest stretches of the summer.
