August 1st, 2023 by Ric Hanson

(Radio Iowa) – The National Weather Service has confirmed a tornado with wind speeds around 75 miles an hour touched down near Clinton Friday night. According to the National Weather Service office in the Quad Cities, the tornado in Clinton County was on the ground for nearly one and a half miles. Another, slightly stronger tornado was reported near the small Jackson County town of Andrew Friday, causing damage to some farmsteads and knocking down some power lines.

The National Weather Service office in Des Moines has been gathering information about a tornado near the Franklin-Hardin County line on Friday. Meteorologists have determined that tornado reached speeds of 90 miles an hour, but they’re still assessing how long it stayed on the ground.

July was cooler and drier than normal

(Radio Iowa) – Weather records show July is the warmest month of the year in Iowa, but state climatologist Justin Glisan says the month that just ended went against the norm. “The average temperature was about 72 degrees and that’s about one and a half degrees below average. So we’re looking at 151 years of records for the state, most likely in the top 30 coolest July’s on record,” Glisan says. Glisan says it wasn’t glove and jacket weather in July.

“Not exceedingly cold but definitely given that it’s the warmest month in expectation — noteworthy that it’s below average — especially the north western half of the state,” he says. “We did have a few days at the end of the month in which we saw 90 degree temperatures we had a one reading in 101 degrees in Keokuk, so we did get some ones at the end, but overall a cooler month.” July did continue the overall dry conditions we saw in May and June, but some areas did get a good dose of rain.

“If you look at the eastern and western borders of the state, we did see some stations with above average rainfall, but overall across the rest of the state departures in the driest part of the state, north central Iowa anywhere from two to three inches below average,” Glisan says. “So you look at the overall statewide average, about three-point-one (3.1) inches preliminarily, and that’s about an inch, inch point, one below average, so 78 percent of normal.” The storms that rolled through with rain made an impact.

“We have seen some widespread precipitation events in July that actually helped improve drought conditions especially in western Iowa and then portions of …northeastern Iowa,” he says. Glisan says the early outlook for August shows some potential for above average rainfall.

(Cedar Rapids, Iowa) – Severe storms rolled through eastern and parts of northeastern Iowa Friday night, bringing large hail and damaging winds. The National Weather Service in Des Moines said there were also reports of funnel clouds in Franklin and Bremer Counties, with one weak twister touching down four-miles north of Iowa Falls in Franklin County, at around 5:45-p.m., Friday. Another tornado was seen 4 miles northeast of Popejoy, in Franklin County. Spotters reported debris was lofted into the air during the event.

KCRG reports the storms initially leaving thousands without power. City officials in Marion said downed power lines and large tree debris were reported. They were advising people to stay away from downed power lines, and assume they’re charged and dangerous.

Hail ranged in size from Marbles and Quarters to ping-pong balls, with some locations near Eddyville and Iowa Falls being hit by Half-dollar (1.25″ diameter) to golf-ball size (1.75″ diameter) hail. The largest hail was baseball size (2.75″ diameter), reported north of Denver, in Bremer County. Winds during the storms gusted to as high as 93 miles per hour near Albion, in Marshall County.

Crews were expected to conduct a damage assessment today (Saturday). The National Weather Service in Omaha says many locations in the eastern part of the State were hit by hail the size of Quarters to as large as Tennis balls and tea cups. The largest stones (2.5-3″ diameter) fell near Elk Horn, NE., at around 6-p.m., and Fremont, NE, at around 5:20-p.m., Friday.
