(Update) Severe storms bring three possible tornadoes, hail, high winds, heavy rain

News, Weather

April 20th, 2023 by Ric Hanson

(Radio Iowa) – Damage assessment teams from the National Weather Service are being dispatched to multiple locations in western Iowa after severe thunderstorms last (Wednesday) night spun off at least three suspected tornadoes. Meteorologist Dylan Dodson, at the weather service office in metro Des Moines, says they don’t have any reports of significant tornado damage, at least not yet. “There were a couple of tornadoes. We don’t have an exact number yet,” Dodson says. “Obviously, there’s going to be surveys that go out for those, but yes, there were a few tornadoes out in western Iowa that were reported.”

Tornadoes are believed to have touched down near Macedonia, Sidney and Thurman, while a funnel cloud was also spotted in the skies near Kiron, though it may not have reached the ground. There are scattered hail reports from Sioux City all the way across Iowa to Dubuque, while baseball-sized hail dinged roofs, shattered windows, destroyed siding and wrecked vehicles in Crawford County. “Most of our hail remained fairly low-end, but there were some bigger sizes out in the west, especially,” Dodson says. “We saw some three-inch hail out there, and then over kind of more in central Iowa, we saw a few reports of inch hail, so about quarter- to maybe half dollar-size.”

North English reported getting more than two inches of rain during the cloudburst, while winds in central Iowa peaked at 62 miles an hour. “The strongest report that we’ve seen so far was at the Des Moines Airport. That was the strongest recorded that we had,” Dodson says. “There were others that were a little bit lower than that, around that 50-mile per hour, maybe 55-mile per hour range.”

Spring arrived on the 20th of March, exactly a month ago, yet Dodson says there’s still snow in the forecast on Friday for parts of northwest and north-central Iowa.

Report predicts climate change could drastically impact corn acres

Ag/Outdoor, Weather

April 20th, 2023 by Ric Hanson

(Radio Iowa) – A report from a national agricultural organization says climate change is already impacting the production of Iowa’s key crops and it offers dire predictions for a more challenging future. John Piotti, president and C-E-O of American Farmland Trust, says shifts in rainfall patterns that bring extremes like drought and flooding, are combining with warmer weather to make it very difficult — if not impossible — to continue the way we currently farm.

The report says 80-percent of our cropland is at risk due to rising temperatures and rainfall changes. By 2040, the report projects only 33-percent of the acres now devoted to corn are likely to remain highly productive with the current corn varieties. Piotti says with the right tools and support, agricultural producers can continue to adapt to climate changes and help reverse the trends.

To ward off the worst impacts of climate change, Piotti says farmers and non-farmers can work to limit global warming and to increase the resiliency and profitability of farmland.

Large hail & heavy rain pummel parts of western Iowa Wednesday night

News, Weather

April 20th, 2023 by Ric Hanson

(Multiple area counties) – Large hail and heavy rain pummeled parts of western and southwest Iowa, Wednesday evening through late Wednesday night. Some areas also saw street flooding as the result of heavy rain. There was photographic evidence of funnel clouds spinning their way downward. Some reached the ground, officially becoming a tornado.

National Weather Service reports and posts on social media showed the extent of the hail damage, which was most severe in Mills, Crawford and Sac Counties, where hail ranging in size from quarters to tennis balls and baseballs, fell and caused heavy damage to vehicles, siding and other property. Widespread hail damage reports came in from Ricketts, Kiron, Schleswig and Charter Oak, inc Crawford County, while just pea-size hail was observed a little after 7:30-p.m., in Atlantic.

Street flooding was reported at some locations in Mills and Pottawattamie Counties. KETV in Omaha says the Classic Café in Malvern had its roof pounded by hail the size of golf balls, and was forced to deal with severe leaking. The restaurant’s owner said water came down so hard it seemed like it was raining inside, but when the storm hit, her staff sprung into action and used everything available to them to capture the leaks and mop-up.

Tornados were observed near Macedonia, Sidney and Thurman, while multiple funnels clouds were observed elsewhere, including as far north as Kiron, in Sac County.  There were no reports of injuries stemming from the recent storms.

Looming El Nino could bring Iowa farmers decent growing season, drought relief

News, Weather

April 19th, 2023 by Ric Hanson

(Radio Iowa) – The La Nina weather pattern is gone, and the National Climate Prediction Center anticipates an El Nino will develop within a few months, which could be welcome news for Iowa farmers. Meteorologist Dennis Todey, director of the U-S-D-A’s Midwest Climate Hub — based in Ames, says El Ninos typically mean a decent growing season for our region, while the extra rainfall could help to knock down the long-running drought. “Conditions look like they’re heading towards El Nino, in the way of the computer models and what we’re seeing in the way of sea surface temperatures,” Todey says, “so they issue what they call an El Nino Watch, which means that an El Nino is likely to be occurring after this.”

While the La Nina lasted for three years, he say the switch to an El Nino pattern is coming on much faster than expected. “The ocean temperatures in the Pacific, especially close to South America, are warming up very quickly,” Todey says. “The computer models continue that progression to likely being El Nino. Reading the advisory now, the El Nino seems more likely by summer which seemed a very quick transition.” Wide areas of Iowa have suffered with drought, and this weather shift could provide some much-needed relief.

“El Ninos typically are better growing seasons for us. They may not be outstanding growing seasons but the tendency is for them to not be bad growing seasons,” Todey says. “Temperatures tend to be more moderate, better chances for precipitation. So for the drought areas, that’s not a bad thing and actually a good thing.” Northwest Iowa’s Monona and Woodbury counties are in the worst category — exceptional drought, while much of Iowa’s western half is either rated in moderate, severe or extreme drought, while broad sections of central and eastern Iowa are listed as abnormally dry.
