(Radio Iowa) – August saw below-normal rainfall — but drought conditions did improve in some parts of the state. The D-N-R’s Tim Hall says some areas didn’t get the rain from thunderstorms. “You sort of have to look at it regionally. And some parts of Southeast Iowa were accepted exceptionally dry in the month of August,” Hall says. August was the fifth straight month with below-normal precipitation, and Hall says the state needs a rainfall rally.”To get out of a drought that’s been sort of lingering and brewing for a couple of years, it’s going to take month over month over month of above normal rainfall,” he says.

“We haven’t seen but one month this year, where we’ve had above normal rainfall statewide. We haven’t seen the conditions that we’d like to see that’ll start to dig us out of this long-term condition.” Rivers and streams are running low in some of the drought areas — which can lead to more problems.”There’s water quality issues that come along with decreased streamflow and groundwater. There’s some communities battling nitrate issues. So in northwest Iowa, it’s not very good. And if you look at the streamflow in southeast Iowa, it is also trending downward,” according to Hall.

The fall months are not normally the wettest of the year in Iowa — but Hall says there is some positive recent history. “Going back to 2016 — a really wet September, 2017 a really wet October, 2018 a really wet September, 2019 a really wet September, and last year a really wet October. So we’ve seen the emergence of the trend I think that shows September and or October being above normal for precipitation,” Hall says. He says the timing of the rains are key to rebuilding subsoil moisture. “There is there’s ample opportunity to get some much needed rainfall going into the winter. Depends how much we get and how much gets locked into the soil moisture before the ground freezes,” Hall says.

The latest drought monitor showed just a slight increase in the percentage of the state that doesn’t have any type of drought.

Special Weather Statement – National Weather Service Des Moines IA
615 AM CDT Tue Sep 6 2022

The National Weather Service reports areas of fog have developed across much of Iowa overnight, and patchy dense fog is reducing visibility to below a quarter of a mile at times in some locations. Please allow extra travel time this morning and use caution while driving. The fog should steadily improve and dissipate after sunrise.

Special Weather Statement for counties in light brown; Dense Fog Advisory until 9-a.m. for counties in dark gray.

(Radio Iowa) – State Climatologist, Justin Glisan says June, July and August have been warmer and drier than normal for the last three years. Glisan says the La Nina weather pattern is to blame and it could impact fall as well. “We still see an elevated chance of warmer and drier temperatures for September and then you look at the seasonal meteorological fall time slice — September October November — we’re seeing that signal through those three months,” Glisan says.

He says La Nina is a cold sea surface temperature anomaly in the Pacific that impacts where the storm tracks set up over the United States. It could hang around through winter. “We don’t want to get ahead of ourselves in terms of winter forecasts. But when we do see that La Nina interface hanging around, we do see a tendency towards warmer temperatures across the southern part of the United States, colder temperatures across the northern part of the United States, and then we’re stuck right in the middle of that interface,” he says. “So it’s just a coin flip right now, but again, too far out seasonally.”

Glisan say the La Nina impact has been felt across much of the upper Midwest.
