Foggy January could mean a wet spring for planting

Ag/Outdoor, News, Weather

February 8th, 2017 by Ric Hanson

The foggy days we saw in January could be an indication of the type of weather farmers ace this spring. Iowa State University Extension Climatologist Elwynn Taylor says it may be folklore, but there is some reasonable evidence to think it will be a wet one. “The folklore message is ‘if you have fog in January, you are going to have a wet planting season.’ Or some people say, 90 or 100 days later it’s going to be awfully wet,” Taylor says. “There is some fact behind that because — why would the fog come in — we’ve started to get the flow from the Gulf of Mexico, which is what brings us our moisture.”

He says this year fits the pattern that can give us a wet spring. “It doesn’t mean we always will, but that was the first point we looked at. Be ready for it to be on the wet side of usual at planting time,” he says. While a wet spring is a possibility, Taylor says another better than average yield is also a possibility.

“That is a distinct possibility — now of course everyone who has farmed in the Midwest knows for many years knows that it’s rare to go more than two or three years with above trend-line yield,” Taylor says. “This would be the fourth year. But it does happen. IN fact, five isn’t an unheard of number of years for staying above trend before it dips back below.”

Snowpack is above average in many areas, spring flooding likely

News, Weather

February 8th, 2017 by Ric Hanson

The U-S Army Corps of Engineers predicts several waterways in Iowa and elsewhere will flood this spring, based on current snowpack conditions in the Missouri River basin. Hydrologist Kevin Low, in the Corps’ Omaha office, says the upper basin snowpack varies. “The Upper Missouri above Fort Peck is below average, the Yellowstone is above average and both North and South Platte headwaters have above-average snowpack,” Low says. “By this point in the winter, we’d normally have went through a bit over 60% of the seasonal peak snow-water accumulation period, so being over halfway, we still could see significant changes with this mountain snowpack.”

Low says with the condition of the current snowpack, rivers in the region will go over their banks this spring in Iowa, Nebraska, Montana and the Dakotas, and the list includes: “The Floyd, Big Sioux and Little Sioux basins in Iowa,” he says.

There has already been some flooding of tributaries due to ice jams. “No significant impacts have been reported to date in connection with these ice jams,” Low says. “Ice jamming is not uncommon in the Missouri basin and we will continue to monitor the rivers for its continued occurrence as we move later into the winter and early spring.”

The Corps’ forecast includes above-average run-off into the Missouri River basin for February, March and April.
