- The National Weather Service issued an Excessive Heat Warning for the Twin Cities area, including Maple Grove, starting Wednesday, July 20 through Friday, July 22, 2016. 

"Dangerously hot and humid conditions" are expected, according to the 
National Weather Service, with temperatures forecast into the 90s. The heat combined with dew points in the 70s to near 80 beginning on Wednesday will bring heat indices of 100 to 110.

"This combination of very hot daytime conditions with very warn overnight lows will result in very dangerous heat conditions,"  the

 According to the National Weather Service, maps are showing this is expected to be the hottest atmosphere for this time of the year compared to 1985-2012 - bringing one of the worst heat waves in the last few decades.

What is an Excessive Heat Warning? An Excessive Heat Warning is issued within 12 hours of the onset of extremely dangerous heat conditions. According to the National Weather Service, the warning is issued when the maximum heat index temperature is expected to be 105 degrees or higher for at least two days and night time air temperatures will not drop below 75 degrees. 

Before the heat begins, the Maple Grove area is also under a Hazardous Weather Outlook and Flash Flood Watch, due to possible overnight thunderstorms July 19 to July 20 with heavy rainfall. 

Maple Grove Hospital Emergency Care Center Dr. Jeffrey Elder provides the following tips for staying cool and preventing dehydration and heat related illness: 
  • Drink water throughout the day is the best defense against dehydration. Don't wait until a child says they're thirsty before offering fluids.
  • Eat healthy foods that naturally contain water like melons and apples. 
  • Seek medical attention immediately for any signs of heat-related illness.
If you're looking for a place to keep cool during the hot summer days, Hennepin County has created an interactive map of cooling centers throughout the county, such as libraries, recreation centers, and more. On the map, 'cooling centers' in Maple Grove include the Maple Grove LibraryMaple Grove Community Center, and AMC Theater.
