KSN Channel 3's meteorologist JD Rudd explained the causes of the rare nighttime temperature spike, known as a "heat burst." First, winds gusted up to 69 miles per hour at around 11 p.m. on Wednesday, when temperatures were still in the 80s. At 12:22 a.m., temperatures were at 85 degrees in the region. Less than 20 minutes later, the temperature spiked to 102 degrees, and winds continued to gust at about 50 miles per hour.
By 3:00 a.m., the temperatures had again fallen and the winds stopped.
