Though temperatures in the 80s the last two days have felt like a welcome respite from the summer heat, National Weather Service Meteorologist John Hendrickson says this weekend will be the start of another warm-up.
“With highs rising back to 90 by Sunday and then they’ll continue to rise, reaching the middle 90s by the middle of next week,” Hendrickson said. “There’s a strong ridge of high pressure in the upper atmosphere that we build in over the plains and it’s going to produce very hot and humid conditions over much of the central U.S.”
Hendrickson said heat indices could reach triple digits when humidity is factored in, which he says is above normal for this time of year.
“Our average high in July is middle 80s. And so we’re looking at temperatures at least ten degrees warmer than normal. And with the high humidities, that’ll produce heat index values from 105 to 110 by the middle of next week,” he said.
There are no heat warnings or advisories posted yet, but Hendrickson says they’re likely when the humidity creeps back up.
