Iowa’s drought conditions lessen very slightly

Ag/Outdoor, News, Weather

July 7th, 2023 by Ric Hanson

(Radio Iowa)  – Dry conditions are lessening — ever so slightly — in Iowa, according to the latest report from the U-S Drought Monitor. The new map shows roughly 87 of Iowa’s 99 counties are in some level of drought, that’s down from 89 counties last week. More than 80 counties are in either moderate or severe drought, while portions of 14 counties in western and southeastern Iowa are in extreme drought. Almost all of the remainder are considered abnormally dry, while moisture levels are only considered normal in parts of Osceola and Dickinson counties in northwest Iowa.

During June, which is typically Iowa’s wettest month, Iowa got less than three inches of rainfall statewide. About five-and-a-half inches would’ve been normal. (Click on the map to enlarge)

Last week’s damaging wind storm now classified as a derecho

News, Weather

July 5th, 2023 by Ric Hanson

(Radio Iowa) – You may have missed it over the long holiday weekend, but the experts confirm a rare derecho (dah-RAY-cho) blasted across far southeastern Iowa last Thursday. It was relatively minor compared to the derecho that swept over Iowa in August of 2020 which is considered the most costly thunderstorm in U-S history. State climatologist Justin Glisan says last week’s powerful, long-lasting wind storm began forming in northeast Missouri and caused plenty of damage across Iowa and two other states. “We saw several rounds of severe weather across southern Iowa including the start of a derecho which occurred in southeastern Iowa and then flowed through Illinois and Indiana,” Glisan says.

Wind gusts in that corner of Iowa exceeded 100-miles an hour, toppling trees and power lines and damaging roofs. Two people were reported hurt in the storm in Illinois. Glisan says the derecho put a severe end to a relatively calm month of June for Iowa. “Temperatures averaged right around 71 degrees,” he says, “and that’s a little over a degree above average with warmer conditions across the northwestern part of the state.” Iowa is seeing drought conditions worsen, week by week, and he says June brought little help — and little rainfall. “In terms of precipitation, rainfall, hail, June is the wettest month climatologically for much of the state,” Glisan says, “and we were definitely below average, just slightly under three inches statewide, and that’s about 2.4 inches below average.”

State Climatologist Justin Glisan

The long-range forecasts indicate July may not be as hot as we’re used to in Iowa. “We’re actually seeing an elevated signal for cooler temperatures across much of the upper Midwest and that’s surrounding and centralized on Iowa, which is a good signal to see on the precipitation side as well, above average chances of wetter conditions.”

The latest map from the U-S Drought Monitor shows only parts of two counties in northwest Iowa are seeing normal moisture levels, while the rest of the state is abnormally dry or experiencing drought, ranging from moderate to severe to extreme. Those extreme drought conditions are in far western Iowa and in south-central and southeast Iowa.
