Marquette, Michigan – Hot, humid weather is set to grip Upper Michigan this weekend, with highs soaring into the 80s and 90s from Saturday through Monday—posing a risk to vulnerable residents without reliable cooling.
According to the National Weather Service in Marquette, daytime temperatures across much of the Upper Peninsula, especially inland areas away from Lake Michigan, could exceed 90°F. Overnight relief will be limited, with lows only dipping into the 60s and 70s, raising concern for heat-related stress and dehydration.
Communities like Iron Mountain, Escanaba, and Marquette are expected to see multiple days of oppressive heat. The probability of temperatures topping 90 degrees on Sunday is especially high in western and central UP counties, including Dickinson and Marquette Counties.
Poor nighttime cooling can strain those without air conditioning, particularly seniors and individuals with preexisting health conditions. Residents are urged to stay hydrated, limit outdoor activity during peak heat, and check on neighbors.
This early summer heatwave may also raise fire weather concerns and strain local utilities. Officials advise preparing now by securing fans, cooling options, and water supplies.
More updates may follow as the heat persists into early next week.
