Intense lightning and flash flood warnings in Iowa today

News, Weather

September 19th, 2019 by Ric Hanson

(Radio Iowa) — National Weather Service forecasters are recalculating the crest of the Missouri River in the Council Bluffs area due to early morning rains. Meteorologist Taylor Nicolaisen at the National Weather Service office across the river in Valley, Nebraska says as much as four inches of rain fell on the north side of Omaha during this morning’s storm. Three-and-a-half inches was reported in Crescent, Iowa. “It will bump up the river marginally, at a minimum, here with the crest that was already forecast,” Nicolaisen says.

The Missouri River crest is starting today in the Omaha/Council Bluffs metro. Heavy rain has been reported in NORTHEAST Iowa and the National Weather Service has issued a flash flood WARNING that includes the city of Dubuque. Forecasters warn hail is possible in the storms striking in eastern Iowa. The storm that hit in parts of WESTERN Iowa early this (Tuesday) also produced a lot of lightning around 6 a.m. In a 50-mile radius of Omaha, the National Weather Service recorded 100 cloud-to-ground strikes every five minutes. “Very loud thunder, obviously quite a bit of trouble. That was waking people up and we had to send alerts out on phones and that was waking people up as well,” Nicolaisen says, “so a lot of people rubbing their eyes early this morning.”

A flash flood WATCH that was in effect for a large swath of Iowa stretching from Council Bluffs to Decorah and the northeast tip of the state was cancelled at 10-a.m. for all but Monona, Harrison, Shelby, Pottawattamie, Mills, Montgomery and Fremont Counties. The WATCH is set to expire at 1-p.m. A Flood Warning is in effect until 3:30-p.m. for Monona, northwestern Pottawattamie and Harrison Counties.

Nicolaisen says there’s a lot of moisture in high levels of the atmosphere. “The atmosphere is absolutely juicy,” he says. “…That’s going to be kind of the trend here. We’re going to at least be capable of heavy rain of and on here in the next few weeks.” Nicolaisen warns there’s a chance of heavy rain in the Missouri River valley — from South Dakota through Kansas and Missouri through the rest of September and into early October.

Iowa scientists warn of ‘sobering extreme heat’

News, Weather

September 18th, 2019 by Ric Hanson

DES MOINES, Iowa (AP) — More than 200 scientists from 38 Iowa colleges and universities have signed on to a climate change statement that warns of “sobering extreme heat projections” for the Midwest that will put people, livestock and pets at risk. The statement released Wednesday says the World Meteorological Association identified July as the hottest month in more than 140 years of record-keeping.

The scientists say the atmosphere and earth’s surface are warming at an unprecedented rate and by mid-century temperatures in Iowa will exceed 90 degrees for 67 days per year, compared to the average of 23 days in recent decades.

Peter Thorne, director of the University of Iowa Environmental Health Sciences Research Center, says adaptations will include expanded disaster preparedness, increased energy use and curtailment of outdoor work and recreation during times of extreme heat.

The University of Iowa Center for Global and Regional Environmental Research has released annual climate statements since 2011. They are vetted by Iowa’s top experts and are intended to place climate change research into an Iowa-specific context and encourage preparedness.
