National Weather Service: expect the same for rest of summer, fall
Although Grand Forks saw some muggy weather just before the big storm in July, the National Weather Service said the month was still cooler than usual.
Temperatures were roughly 1.2 degrees below normal, with an average temperature of 67.4 degrees, according to the agency’s sensors at Grand Forks International Airport.
The highest temperature was 92 degrees on July 20 the day before the storm, which produced several tornadoes, and the lowest was 46 degrees on the night of July 2.
Precipitation was two thirds of an inch higher than normal as well, reaching a total of 3.7 inches for the month, about 0.55 inches more than normal.
Much of that rainfall, though, came from the July 21 storm when 2.79 inches fell.
“It dumped quite a bit of rain,” said Brad Hopkins, a meteorologist with the weather service’s Grand Forks office.
There were three days when the temperature was warmer than 90 degrees, he said. “You’d expect to have more (90 degree days) this time of the year.”
“(July) was a little bit cooler and a little bit wetter (than usual),” he said. “June was a little bit warmer and a little bit dryer. All and all it comes out as a wash. The two months balance out to normal values.”
For the month of June, the average temperature was 65.3 degrees, 1.3 degrees warmer than normal.
Looking into August and through October, it seems the slightly lower temperatures will continue, Hopkins said.
Looking from October to January, he said, the pattern will change a bit. “There was talk about El Niño shifting a little bit so we might see warmer temperatures this winter,” he said. Precipitation also looks normal, which means a normal amount of snowfall, he said.
“But it’s still very early, there’s really no way to tell what the flood season is going to be like next year,” he said. “We won’t know what that’s like until around March. That’s when we get a better feel for things.”
