(Radio Iowa) – Many Manchester residents are dealing with storm damage after nearly two inches of rain caused flash flooding and wind gusts of up to 58 miles an hour hit the city at 11 a.m. Wednesday. Delaware County Emergency Management Coordinator Mandy Bieber says the north end of Manchester seemed to be hit hardest. “We sustained tree damage, had some power outages,” she says. “We had one report of a livestock building being flipped over and then two houses damaged by falling trees.” Bieber says utility crews were able to remove tree limbs from power lines and restore electric service quickly.

Manchester City Manager Tim Vick says a street light in downtown Manchester was damaged. “The wind somehow managed to turn that on us,. If you take a look at it, it does not look like the pole is bent or anything, it just needs to be repositioned. That’ll take some work,” he says. “We’re not quite sure how we’re going to do it just yet. We’re analyzing the best way to get that twisted back into place.”

Officials say intense rain fell elsewhere in Delaware County on Wednesday, but Manchester appears to be the only area where the storm caused property damage.

(Radio Iowa) – There’s been a slight uptick in the amount of water flowing into reservoirs in the Missouri River Basin over the past two months, but the Army Corps of Engineers says it’s not enough to reverse long-term drought conditions along the Missouri River corridor. Radio Iowa’s O. Kay Henderson reports.

The Army Corps of Engineers is slightly increasing the water flow out of the Gavins Point Dam in South Dakota. That will help barges and other vessels navigate the Missouri River through Sioux City, Omaha, Nebraska City and Kansas City. However, the Army Corps intends to conserve water releases if there is no commercial navigation in a given area.

The National Drought Mitigation Center estimates that 62 percent of the Missouri River basin is abnormally dry or in a drought.

(Radio Iowa) – As we survive the steamy, hot summer, some Iowans may find solace in pondering the cooler weather of the inevitable change in seasons, but the new edition of the Farmers’ Almanac predicts anything but a mild winter ahead. Editor Peter Geiger says the winter forecast map carries just five words floating over Iowa and the Midwest: “Hibernation Zone, Glacial, Snow-Filled.” Geiger says the publication is calling for an exceptionally snowy, extremely cold winter for 2022-’23.

“When we look at the predictions, we talk about some snow in late October, but then we talk about it being heavy snow on Thanksgiving. We talk about significant snow after that. We talk about heavy snow on the 1st, 4th and 7th of December,” Geiger says. “It’s going to be one of those unrelenting kind of winters where you dream about how nice it is when it’s hot in the summer.” While parts of Iowa have seen triple-digit heat indices multiple times this summer, Geiger says the winter before us will prove to be equally extreme.

“What really scares me about the winter is the cold,” Geiger says. “So we talk about this sharp cold, maybe as low as minus-40. I don’t think it’s going to be minus-40 in Iowa, but within the region, you’re going to see some really cold temperatures almost from the middle of January through the early part of February, and then some snow even in March.” The new edition of the almanac is due on store shelves August 15th and Geiger says it will include tips for coping with the predicted high cost to heat our homes during the frigid months.

“For example, you can use bubble wrap. If you spray a window with water and then put bubble wrap on, it insulates the window for the winter,” Geiger says. “I mean, it’s very simple, very inexpensive but it’s very possible.” Founded in 1818, the Lewiston, Maine-based almanac boasts a forecast accuracy rate of 75-to-85-percent which Geiger says is derived from a formula developed more than two centuries ago.

“It’s based upon sunspot activity, planet positions, the effect the moon has on the earth, and we actually have a page in this year’s almanac that talks a little bit about how we go about doing it,” Geiger says. “When we say it’s going to be minus-40 degrees, I think it’s an indication of how potentially cold it could be, as opposed to the fact that you can count on minus-40.”

In addition to weather predictions, the Farmers’ Almanac contains all sorts of information on gardening, cooking, home remedies, folklore, managing your household, living in harmony with nature, and more.

(Radio Iowa) – Three state agencies are developing guidelines and real-time resources for city and county officials who may have to restrict water usage during a drought emergency. Tim Hall of the Iowa Department of Natural Resources says the first-ever state “drought plan” would leave decisions about limiting water usage to local officials.  “We’re trying to set up a framework that will help local communities, local water utilities, emergency management folks be prepared to deal with a drought when it comes by answering those questions: ‘What should be do and when should be do it?’ and we can provide the data and the information that helps them make those decisions,” Hall says.

The latest information from the U.S. Drought Mitigation Center shows there are “extreme” drought conditions in four northwest Iowa counties, but water shortages haven’t dropped to the level of what’s called an “exceptional” drought. “We have seen droughts on a fairly regular schedule. We saw, of course, a significant drought in 2012,” Hall says. “We saw some very dry years in 2020 and 2021. This year is looking pretty dry as well.”

In July, state officials hosted meetings in Sioux City, Cedar Rapids and Creston to hear from water utilities, local communities, county emergency managers and industries that use water. A final virtual meeting is being held this (Wednesday) morning with about 70 representatives of those groups. “We’re almost to the end of the stakeholder piece,” Hall says. “We have a science and data team that’s looking at information that’s available and how we might establish some trigger mechanisms for the state, so we are right in the middle of developing of the heavy duty stuff of the plan right now.”

Hall is the hydrology resources coordinator for the Iowa Department of Natural Resources. On Thursday, Hall will be issuing a statewide summary of water resources. He says water levels in some areas of northwest Iowa are alarmingly low. “As the temperatures start to climb and we don’t see any precipitation, it could get a little bit rough in some places,” he says.

The situation, though, isn’t currently as dire as the last major drought of 2012, according to Hall.  “But on a local basis, there are some areas of northwest Iowa that are struggling to see what their water situation is going to be in three weeks, four weeks, six weeks if we don’t get much rain,” Hall says.

According to the state climatologist, unseasonably dry conditions persisted across Iowa last week and the drought intensified in the state’s northwest corner.

Tuesday’s High in Atlantic was 95. The Low was 75. Last year on this date the High in Atlantic was 80 and the Low was 52. The Record High on this date was 107 in 1930. The Record Low was 42 in 1907.

(Radio Iowa) Much of Iowa’s expected to roast in this week’s heat wave — which may end up lasting much longer — and it follows a very steamy July. State climatologist Justin Glisan says the just-ended month was one-degree warmer than normal statewide and we had one-inch less of rainfall than the average. Glisan says Iowa’s farmers are especially concerned about forecast models that show more of the same during August. “We’re getting into the teeth of the growing season but also the warmest part of the year for Iowa late July and August,” Glisan says, “and we’re definitely going to turn on the furnace this week.” The Climate Prediction Center is releasing its maps for expected temperatures and precipitation during August — and both show the hot, dry trend will continue for Iowa during the month ahead.

“It doesn’t bode well for the drought conditions that we’re seeing, especially in northwestern Iowa where we have D1 to D3 drought, the extreme drought category,” Glisan says. “We would like to see timely rainfall to hold the crop on, but right now, the probabilities, they’re not working in our direction.” If there’s a bright spot to the past month, Glisan notes there was no severe weather anywhere in Iowa during July.

“We don’t have severe weather, we don’t have thunderstorms, we don’t get rainfall and hence, drought conditions expand,” Glisan says. “We saw similar behavior last year at this time. Drought was more pervasive last year, D1 to D2 across much of the northern two thirds of the state.” While we’re in the third year of a La Nina pattern, Glisan says it’s still too early to say if the warmer, drier weather will last into the fall months.
