Spring has officially sprung and that means heavy rains are on the way, specifically from eastern Texas into Ohio this week. Any fieldwork and planting will come to a halt, and Nutrien’s principal atmospheric scientist Eric Snodgrass warns of significant flooding risk.
“We’ve got a swath of the country that could pick up anywhere between 5” to upward of 12” of rainfall,” he told “AgriTalk” host Chip Flory on Tuesday. “In the Ohio River and in the lower Mississippi River, there’s going to be a major flood trend.”
USDA meteorologist Brad Rippey says there’s a chance for even higher totals in some areas.
“There are some indications we could see totals up in the 18" range likely across Arkansas on into parts of northwestern or northern Kentucky before this is all said and done,” Rippey told AgDay’s Michelle Rook.
Meteorologists have been warning of drought conditions for months now, so this type of weather system should have a positive impact, right? Wrong – Snodgrass explains this is the wrong time, wrong place.
“This is not a place where we’re missing out on moisture. This is the place we saw flood back in early March and even in parts of February,” he says.
The good news is snow is in the forecast for some areas in need of moisture, such as parts of the Dakotas and Minnesota. But unfortunately, it likely won’t be enough.
“The central United States is at about a 60% drought risk. Some of the best weather forecast models we have out there are trying to put the epicenter of that drought somewhere between Missouri, Nebraska, South Dakota, Iowa and southern Minnesota by the time we get into July and August,” Snodgrass says. “When you think about those particular states, developing drought from spring to summer in any year is somewhere in the neighborhood of 28% to 38%. Essentially, the risk is doubled this year.”
Snodgrass explains the canary in the coalmine for a drought will come from a combination of the Gulf of Alaska ocean temperatures and the Bermuda high, which is an area of high pressure that can influence weather patterns and tropical systems. If the Gulf of Alaska ocean temperatures begin dropping this summer, it’s a bad sign.
“If in June we start to watch the Gulf of Alaska ocean temperatures drop, that’s actually symptomatic of the atmosphere losing momentum. And if it loses momentum, there’s nothing to keep the Bermuda high over Bermuda,” he says.
What It Means For Planting
With flooding in the East and drought in the West, Snodgrass plans to use the Mississippi River as his main moisture boundary this year.
“If you’re east of it, I think spring is super tight. If you’re west of it, we have got to return moisture to Kansas, Oklahoma, Texas and Nebraska in order to beat back any sort of risk of drought going forward,” he says. “I really just think it’s West versus East this year on who’s got the favorable conditions early versus the risk in the middle of the season.
Taking a closer look at that outlook for a wet spring in the East, Snodgrass specifically says the month of April is shaping up to be one week on and then one week off.
“Right now, we’re week on with heavy rains. Next week, we get cooler and drier. Week three in April goes right back into an active pattern,” he explains. “What I want to know is if week four of April brings in cold conditions right after Easter. If that occurs, we just threw the brakes on any early planting hopes. Right now though, it appears that most of spring would favor tighter windows in the East.”
Despite the current outlook, a challenging spring and dry summer doesn’t mean game over.
“Any sort of problem we thought we saw will be gone in a heartbeat with good July rainfall. We are not settled. There’s a lot to understand and change with this pattern,” Snodgrass says. “Let’s say we do have drought, but you don’t have the heat stress. We can make a huge crop in drought conditions, so don’t forget that.”
