Minneapolis, Minn. – Minnesota’s break from summer heat won’t last much longer. Comfortable temperatures today will give way to a prolonged stretch of hot and increasingly humid weather beginning this weekend, with heat index values climbing above 100 degrees across much of central and southern Minnesota early next week.
According to the National Weather Service in the Twin Cities, temperatures will steadily increase through Saturday before widespread 90-degree highs settle into the region from Sunday through at least Tuesday. As humidity rises, afternoon heat index values are forecast to reach the upper 90s to around 105 degrees, creating potentially dangerous conditions during the hottest part of the day.
The Twin Cities are expected to climb from the low 80s Thursday into the mid-80s Friday, before reaching the upper 80s Saturday. Highs are then forecast to approach 96 degrees Sunday, with heat index values near 99 degrees, followed by 91 degrees Monday with a heat index near 97 degrees. Other communities, including Mankato, St. Cloud, Hutchinson, Alexandria and Albert Lea, could experience heat index values between 100 and 105 degrees early next week.
The combination of prolonged heat and increasing humidity will raise the risk of heat-related illnesses, especially for those working or exercising outdoors. Residents should stay hydrated, wear lightweight clothing, take frequent breaks in air-conditioned spaces and check on older adults and others who may be more vulnerable to the heat.
The hot weather pattern is expected to persist into next week, and additional heat-related advisories may be issued as confidence in the hottest conditions continues to increase.
