Residents here sweated through a third straight day of triple-digit temperatures, though the National Weather Service said the sweltering heat was unlikely to set any records.

The temperature in Bismarck mid-Sunday afternoon was 106 degrees, and in Dickinson and Williston it was 100. Other major North Dakota cities were in the 90s.

It was the sixth day in July that Bismarck had seen high temperatures over 100 degrees, said Vern Roller, a technician with the National Weather Service in Bismarck. That, also, was not close to a record - in July 1936, there were a total of 12 days of triple-digit temperatures, he said.

Randy Bina, chairman of the weekend Prairie Rose State Games in Bismarck-Mandan, said the scorching weather did not cause many problems for athletes. He said he was aware of one young softball player who had sought medical attention from trainers because of the heat, but that the person quickly recovered.

"I believe everyone responded in a responsible way and drank plenty of fluids, and took themselves out of games if they needed to," Bina said.

He said the heat prompted some athletes not to take part in the games, but others signed up for events onsite despite the weather - including a 50-mile cycling event on Sunday. Bina said he expected participation to be close to the 5,600 athletes who took part the last time the Games were held in Bismarck, in 2003.

"I'm definitely pleased with those numbers, considering the extreme heat," he said.

The Weather Service forecast called for a slight cool-down early in the week.

"It looks like the triple digits are done here for the next few days, although there's still some 90s in the forecast," Roller said. "It looks like a little cooler, but still some 90s, which is going to feel, probably, cool next to what we've had."

Some of the high temperatures called in by Weather Service observers in rural towns over the weekend included 108 degrees in Linton, 110 degrees in Fort Yates and 112 degrees in Ashley, Roller said.
