A climatologist who studies drought conditions says a “bulls eye of dryness” is centered on the nation’s midsection. Mark Svoboda, of the National Drought Mitigation Center says part of the problem is the winds in Iowa are coming from the southwest — states like Arizona, New Mexico and Texas where it’s bone dry. “This is kind of what we call a drought feeding on itself and I think we have the potential to really escalate this drought in the summer if we don’t get the rainfall they’re calling for over the next five days,” Svoboda says. “So if there’s any silver lining in the cloud — or lack of clouds, if you will — this exact region — we need that heavy rainfall forecasted over the next five days for this very region, the bulls eye of this dryness, because right now it looks like July, early August out there.” Iowa, Missouri, Nebraska, Illinois and Indiana have had a signficant “dry down” according to Svoboda, because there was little snow fall in the winter and a relatively dry spring.
“But the temperatures have been the real story,” Svoboda says, “so when we look at temperature departures over the last, say, three months, we’re seeing temperatures eight to 10 degrees or more above normal across eastern Nebraska, Kansas, Missouri and Iowa.” The most severe Midwest drought in recent memory happened in 1988 and ’89. Normal rainfall for this time of year is about an inch per week, according to Svoboda, and it would require significant rainfall this weekend to erase the moisture deficit in much of the Midwest.
“This rain this weekend, this next couple of days, is pretty darned critical to sort of tell us how we’re sitting in late June, early July,” Svoboda says. “…We have no soil moisture down to three feet virtually everywhere. When people are talking about digging posts and doing work out in their yards — and I’ve seen this myself personally, too — I’m mean, there’s virtually nothing down to three or four feet.” The National Drought Mitigation Center is based at the University of Nebraska in Lincoln. The latest forecast for the state of Iowa suggests there will be “chances for showers and thunderstorms throughout the next several days.”

Heat and humidity can make for a dangerous — even deadly — combination. Today (Thursday) is Heat Awareness Day in Iowa. Jeff Johnson, warning coordination meteorologist at the National Weather Service, says Iowans can benefit from a refresher course on the risks of hot weather. “It’s intended to remind folks that in the summertime in Iowa, particularly in late June, July and early August, that we can have periods of extreme heat and humidity,” Johnson says. “That is actually a public health concern.” Johnson has some simple advice for beating the heat.
“Drinking plenty of water, avoid alcohol, slow down during the day in the heat and do your exercise early in the morning or late in the evening, and dress in light-colored clothes,” he says. “If you know of an elderly person or someone in bad health who doesn’t have air conditioning, be sure and check on them, maybe even encourage them to get to somewhere that does have air conditioning.” We’re coming off one of the warmest winters –and springs — in Iowa history, so the summer ahead could be steamy. Johnson says last summer wasn’t too brutal.
“We didn’t hit 100 in Des Moines but I think we did elsewhere in the state,” he says. “We did have some heat events. One week in July of last year, we had heat advisories out every day for a week. We did have kind of a heat wave. It wasn’t extreme like in ’95 or ’88, but we did have some heat last year.” The first day of summer is next Wednesday, June 20th.
