Coming cooldown is a short one, with 100-degree weekend temps
Hot, hot, hot. And windy and humid, too.
Keeping cool was the order of the day Tuesday in the Twin Cities and across much of southern Minnesota as temperatures soared into the upper 90s and heat indexes — what it actually feels like outdoors when combining the temperature with the relative humidity — hit triple digits.
An excessive heat warning went into effect at 11 a.m. in the seven-county metro area and was scheduled to last until 8 p.m. The combination of heat and humidity made for "a dangerous situation in which heat illnesses are likely," the National Weather Service said in issuing the warning.
To keep cool, a trip to Duluth would have done the trick. The temperature in the port city was a brisk 55 degrees at noon Tuesday and not expected to rise much above 70.
Across the rest of the state, however, the scorching heat was on. Heather Teresiak and her husband, Weston, heard the forecast and made a "spur-of-the-moment" decision to take their kids, Chip, 1, and Eden, 4, to the Bunker Beach Water Park's wave pool in Coon Rapids.
"We'll be here most of the day," said Heather, of Oak Grove. "It's a good day to cool off and keep the kids busy."
With temperatures forecast to break 100 degrees Sunday and Monday, "we'll likely be back," Weston said.
Sprinklers kept patrons cool standing in line on the hot concrete, and shade tents were put up to protect them from the beating sun. Extra lifeguards were on duty, too, allowing them to rotate positions every 45 minutes and take breaks in the shade.
The pool, which Anoka County Parks Director Jeff Perry describes as "a million gallons of fun" also set out free water coolers. Swimmers, sometimes, "forget to drink water," he said.
Heat-related illness happens when the body isn't able to sufficiently cool itself under extreme conditions. Staying hydrated is vitally important when dangerous heat rolls in, the Minneapolis Department of Health said, because fluids help keep the body's ability to cool itself through sweat.
Staying in air-conditioned spaces and avoiding strenuous outdoor activities during the midday hours when the sun is strongest also are good strategies, the Health Department said.
For those, such as postal workers, who have to be outside, the Health Department recommends light-colored, lightweight, loose-fitting attire, which can help reflect the heat. Postal workers also are reminded to wear hats, get in the shade when possible and take sufficient amounts of water and ice with them out on routes, spokesperson Desai Abdul-Razzaaq said.
With dangerous heat indexes forecast to reach up to 105 degrees, both Hennepin and Ramsey counties opened buildings and recreation centers to offer free places to linger in climate-controlled comfort. Libraries and shopping malls also offered relief.
For those without air conditioning and unable to make it to a cooling center, don't rely on an electric fan, the Health Department said. When it's 90 degrees, fans don't help cool the body, the Health Department said. "Using wet cloths, showers or baths, or a spray of mist on exposed skin will help cool the body temperature," it said.
Air conditioner repair crews responded Tuesday to hundreds of calls from customers who didn't test their air conditioners this spring and had just now found they aren't working.
"We are totally booked up," said Steve LaTart marketing director with Dean's Home Services in Maple Grove.
LaTart said tackling a malfunctioning air conditioner is not a do-it-yourself job. For those with working units, once a home is cooled to the desired temperature, leave it on, even if you're not home.
"It takes more energy and power and the unit has to work extra hard" to bring the temperature back down again, he said.
One place to avoid is a car. In extreme heat, "car interiors can reach lethal temperatures in a matter of minutes," causing heatstroke, the National Weather Service said.
Several Minneapolis public schools shifted to an e-learning day because of the heat. School buildings without air conditioning closed to the public Tuesday included Bryn Mawr, Field, Hiawatha, Kenny, Kenwood, Longfellow, Northrop and Pratt community schools, the upper and lower campuses of Lake Harriet Community School, Sheridan Dual Language Elementary School and Roosevelt High School.
Tuesday's high officially hit 96 degrees in the Twin Cities, according to the National Weather Service. The record high for June 14 is 98 degrees, set in 1987.
Lynn Holeman of Forest Lake said she didn't mind the heat, which has come after a relatively cool spring.
"It's a nice day," she said while waiting in line at the Bunker Beach swimming pool. She was there with other parents and friends to celebrate Sophia Harvey's sixth birthday. "I love it, but I could do without the humidity."
Tuesday's one-day heat blast is also a preview. After a chance of showers Wednesday and temperatures in the 80s Wednesday through Friday, the dangerous heat and humidity will return with a vengeance by the weekend.
The last time the metro area hit 100 degrees was May 28, 2018. In the month of June, 100-degree readings have happened only four times in the metro since 1956, with the most recent on June 7, 2011, when the temperature reached 103, according to the Minnesota State Climatology Office.
That could happen Sunday and Monday as an intense heat wave is predicted to deliver high temperatures between 100 and 105 degrees across southern and western Minnesota, the Weather Service said.
