(Radio Iowa) — While parts of Iowa had record high temperatures in the low 90s on Thursday, forecasters say cooler, wetter weather will likely dominate much of the rest of the month and well into June. During a National Weather Service briefing, climatologist Martha Shulski (SHUL-skee) says heavy rain will spread across Iowa and much of the Northern Plains next week, raising the critical risk of renewed flooding. “The prediction is in the three-to-five inch range, so a pretty active pattern,” Shulski says. “These forecasts have been pretty consistent which gives you some higher confidence in the forecast actually verifying. Certainly, it’s something to look out for in terms of impacts over the next week.”
In spite of a few scattered hot and humid days, Iowa’s weather has been much cooler than normal this spring and forecasters anticipate that pattern will remain. “Continued higher probability for below-normal temperatures for a swath in the central U.S.,” Shulski says. “This is combined with the increased probability of wetter-than-normal conditions for June.”
Thanks to the El Nino, it’s possible the cool, wet weather will last well into summer, as will the risk of more flooding, as the ground remains saturated in many parts of the state.

(Radio Iowa) — Near-record heat is in today’s (Thursday) forecast, with 80s expected across northern Iowa and low 90s for Iowa’s southern half. With the hot, humid air comes the greater risk of severe weather. Meteorologist Brooke Hagenhoff, at the National Weather Service in metro Des Moines, says some areas may see summer-like temperatures 20-degrees hotter than usual. “While we’ve been cooler-than-normal for most of May so far, it’s a pretty big change here, especially today, the warmest day in our seven-day forecast,” Hagenhoff says. “It’s really due to the increased southerly flow which is allowing warmer air to come up across the Southern United States and into Iowa.”
With the dramatic change as we shift from cooler to much warmer weather, there’s always the risk of rough weather, including powerful thunderstorms. “For today, we’re looking at a risk over mainly central and northern Iowa and the main threat with that is going to be hail and possibly damaging winds,” Hagenhoff says. “That will be mostly confined to this evening and tonight.” Many Iowans are rarely very far from their smart phones, which can be set up to provide you with potentially-life-saving weather data. “We know that with the warmer weather, after the cool start to spring, a lot of people are antsy to get outside,” Hagenhoff says. “It’s important that whether you have outdoor plans or not that you have ways while you’re outside to receive severe weather warnings and information, just so you’re prepared.”
The weather should cool a bit Friday and Saturday, she says, with highs by Sunday only creeping into the 60s. On the subject of severe weather, Iowa saw 69 tornadoes touch down last year. So far this year, there hasn’t been a single twister reported statewide.
(Radio Iowa) — We’re now at the halfway mark of tornado season in Iowa, and so far, there hasn’t been a single twister reported statewide this year. While tornadoes can strike during any month, April, May and June are considered the peak months. Meteorologist Chad Hahn, at the National Weather Service, says there is a reason why it’s been such a quiet period for the storms. “Of course, we’ve been experiencing a great deal of precipitation and certainly we’ve seen that with the ongoing river flooding across portions of the state,” Hahn says. “We’ve been cooler than normal over the past few weeks and because of that, we haven’t been able to get the thunderstorm activity going like we’d typically expect in the spring months here.”
After the prolonged cold spell, warmer weather should be moving in over the next few days. Hahn says that could bring a chance of thunderstorms, though likely nothing too rough. “At least at this point, the week looks fairly quiet, but we do see the mercury starting to rise off in the horizon,” Hahn says. “Of course, it’s not a matter of if, it’s when. We can’t let our guard down because we know when that switch flips, we’ll have to be ready to take the appropriate action if we have severe weather.” Hahn says Iowans should be prepared. “I encourage the public to know that we will get severe weather,” he says. “It’s not a matter of if, it’s when. When that does happen, it’ll likely go from zero to 60, so we need to battle the complacency bug and be ready for severe weather when it does strike.”
Last year, there were 69 tornadoes statewide with the most notable hitting Bondurant, Marshalltown and Pella on July 19th. Over the past decade, Iowa has seen as few as 16 tornadoes during all of 2012 and as many as 88 tornadoes in 2014.
