It won't be just the deep-fried onion rings and cheese curds sizzling as the Minnesota State Fair heads into a possible record-breaking heat wave.
A heat advisory goes into effect Sunday through Wednesday, ushering in temps and sweltering dew points that will make it feel 100 degrees and hotter.
That could make this the hottest State Fair since 1948 — the last time there was a four-day streak of temperatures higher than 94 degrees, according to the National Weather Service.
"It's going to be rough," said Kristy Kegley, a lemonade stand manager who hired extra staff in anticipation of the heat wave drawing long lines.
Fair organizers have prepared by setting up large fans misting water at the two medical aid areas that fairgoers of all ages flocked to in Saturday's 90-degree heat. Extra medical responders and ambulances from Regions Hospital are also on site in anticipation of a spike in heat-related medical incidents.
Annual fairgoers like Natalie Woods Grosfield of Bemidji didn't let the sticky heat affect her trip.
"We know it's hot, but what the heck — it's better than rain," she said as she splashed water on her 4-year-old granddaughter.
At the CHS Miracle of Birth Center, large fans cooled the animals and the crowds cooing over 2-day-old piglets. Mary Olson, co-chair of the center, said they're sprinkling water on the cows and pigs and putting extra fans out to keep them cool during the heat wave.
