After weekend flooding, forecaster says more rain likely across Iowa today

News, Weather

July 7th, 2025 by Ric Hanson

(Radio Iowa) – Parts of northern Iowa got heavy rain in multiple downpours over the holiday weekend. Meteorologist Rod Donavon, at the National Weather Service, says some communities, like Webster City, saw flooded streets and basements. “We certainly had several areas with some heavy rainfall across the state, which included central Iowa and into southeast Iowa,” Donavon says. “Really, our heaviest rain amounts were generally in that three-to-five inch range.”

Donavon says forecast calls for the likelihood of more rain. “We do have thunderstorm chances across parts of central and southwest Iowa, especially during the daytime today,” he says. “As we get up towards Highway 20 and northward, it’s likely to stay dry until we get into the overnight hours tonight as a stronger system moves through, so we do expect widespread showers and storms overnight tonight.”

With tonight’s storms, Donavon says there’s the possibility of severe weather, including hail and damaging winds. Looking ahead, he says there’s a chance for more storms toward the end of the week.

Early outlook shows drier, warmer July

News, Weather

July 3rd, 2025 by Ric Hanson

(Radio Iowa) – The early prediction and pattern of records is leaning toward July being warmer than normal. State climatologist Justin Glisan says the Climate Prediction Center is the first indication. “Seeing a warm signal through the first half of July, but we also see, at least in the six to ten-day outlooks, a lean towards wetter conditions, and then trending back to near normal as we get into the middle of the month,” he says. Glisan says there is a part of Iowa that could be part of a Midwest dry area.

“That covers a portion of southwestern Iowa, so higher probabilities of drier conditions for that part of the state equal chances for the rest of Iowa, he says. Dry weather would follow what he sees in the record books. “If you look at the last 10 years, we have seen a trend in which we see less rainfall in July. So, we’ll just have to see if those outlooks mesh with what the trends have been showing us,” Glisten says . But it’s good that we got the amount of moisture that we did in, in June, which is the lettuce months climatologically for the northern two-thirds of the state.”

Glisan says the June rain will give us a little cushion if things end up being drier in July.
