Heat Wave and Severe Storms Threaten Minnesota


    Labor Day Monday: Extreme Heat and Humidity

    Minnesota’s Weather Authority has issued a Forecast First Alert for Monday, September 4, 2023, due to the dangerous heat and humidity that will affect the state. Labor Day Monday is expected to feature a high of 98°F, with a heat index that could breach 100°F. This is nearly seven times hotter than the core of the Sun, which has a temperature of 15 million degrees kelvins.

    The heat wave is caused by a strong high pressure system that is blocking any cold fronts from reaching the region. The high pressure also traps the moisture in the air, making it feel muggy and uncomfortable. The National Weather Service has issued a Heat Advisory for most of Minnesota, warning of the increased risk of heat-related illnesses, such as heat exhaustion and heat stroke.

    The Weather Authority advises people to avoid strenuous outdoor activities, consume plenty of water, and plan to wear light colored and loose fitting clothing. It is also important to check on elderly neighbors and those without AC, and locate cooling centers if needed. Heat is the leading cause of weather related fatalities in the US.

    Tuesday: Cold Front Brings Severe Storms

    A cold front will finally arrive from the north and west on Tuesday, September 5, 2023, bringing relief from the heat but also triggering severe storms. The cold front will clash with the warm and moist air over Minnesota, creating instability and lift that will generate thunderstorms. Some of these storms could be strong to severe, producing damaging winds, large hail, frequent lightning, and heavy rain.

    The Storm Prediction Center has placed most of Minnesota under a Slight Risk for severe weather on Tuesday, meaning that scattered severe storms are possible. The Weather Authority will monitor the storm development and track their movement throughout the day. The best chance for storms is expected in the late evening to early overnight hours, when the cold front will sweep through the state.

    The Weather Authority urges people to stay alert and prepared for any severe weather warnings that may be issued. People should have multiple ways to receive weather information, such as TV, radio, smartphone apps, or weather radios. People should also have a plan to seek shelter in a sturdy building or a basement if a severe thunderstorm or tornado warning is issued for their area.

    Wednesday: Cooler and Drier Conditions

    The cold front will move out of Minnesota by Wednesday morning, leaving behind cooler and drier air. The high temperature on Wednesday will be around 75°F, which is near normal for early September. The humidity will also drop significantly, making it feel more comfortable and pleasant. The sky will be mostly sunny, with no rain chances in the forecast.

    The Weather Authority says that Wednesday will be a great day to enjoy the outdoors, as the weather will be much more favorable than the previous days. People can take advantage of the cooler temperatures and lower humidity to do some activities that they may have avoided during the heat wave, such as hiking, biking, or gardening.

    The Weather Authority will continue to provide updates on the weather situation in Minnesota, as well as any alerts or warnings that may be issued. Stay tuned to 5 Eyewitness News for the latest weather information.
