A storm system over east central Missouri will lift into the Ohio Valley and produce snow over much of Iowa through Wednesday morning. Moderate to heavy snowfall will occur over the southeast half of Iowa and parts of Missouri and Illinois. Strong north winds will cause blowing snow and reduced visibility in these areas, making travel hazardous. Winter storm warnings are posted for a large part of the southeast half of Iowa with winter weather advisories from southwest into parts of north central and northeast Iowa. The snow will end on Wednesday, with cool and dry weather expected for the remainder of the week.

(National Weather Service/Dsm) — A storm system moving across the Southern Plains and lifting into the Ohio Valley will produce snow over Southeast Iowa today through Wednesday morning. Moderate to heavy snowfall is still expected across far Southeastern Iowa and parts of Missouri and Illinois. Strong north winds will cause blowing snow and reduced visibility in these areas, making travel hazardous. Winter storm warnings are posted for parts of Southeast Iowa with winter weather advisories for parts of South central to East central Iowa. The snow will end on Wednesday, with cool and dry weather expected for the remainder of the week.

Forecasters say another winter storm is headed for Iowa that has the potential to drop significant snow on parts of the state. Meteorologist Roger Vachalek, at the National Weather Service, says this system should drop the deepest snow on a different area of Iowa from last week’s storm. He says the system will arrive late tonight and early tomorrow and it should bring snow to the southeastern half of the state. The heaviest totals are expected in the southeast. Cities like Ottumwa, Fairfield, Burlington and Keokuk could see between five and nine inches of snow. Parts of central Iowa may only see two to four inches, with little-to-no snow expected in the northwest. Vachalek says there’s another issue with this approaching storm.
Some strong winds may accompany the storm, with gusts around 15 to 25 miles an hour, so blowing snow could become a visibility problem for motorists. The National Weather Service has issued a Winter Storm Watch for parts of southeast and south-central Iowa from late tonight into Tuesday. Cities in the advisory include: Lamoni, Ottumwa, Iowa City and Davenport. In far southeast Iowa, Lee and Des Moines counties are under a Winter Storm Warning from 3 tomorrow morning until midnight tomorrow night. Late last week, another snowstorm coated much of Iowa in white, dumping the most snow in the Sioux City area, which reported ten inches.
Whether the drought continues or not, Iowa farmers will soon be able to check soil moisture levels at a dozen key spots statewide.
Elwynn Taylor, an agronomist at the Iowa State University Extension, says moisture levels can vary greatly over short distances, but this new network will offer farmers good ballpark figures. “People that have a sandy place and a place with clay already know they have great differences,” Taylor says, “but still, if we have some idea on a very common soil for the county, if we know what is going on there, it will give an idea of how things are changing and the likely direction it will be moving in.”
I-S-U’s Department of Agronomy is upgrading weather stations at several research and demonstration farms. At least 12 should be fully functional in several weeks when spring arrives. Farmers can always dig a hole themselves to try and gauge the soil moisture, but Taylor says doing so accurately is a hassle. “To really know, you have to get a measure of soil from a certain depth, weigh it, dry it, weigh it again and see how much water the drying removed from it to know how much water was really there in your soil,” Taylor says. “It gets to be a real headache and, of course, people aren’t going to do that on a day by day, week by week, month by month basis.”
At each station, moisture sensors will be placed a foot, two feet and four feet deep in the soil. Readings will be taken every 15 minutes and sent by cellular phone text messages to the network. Each station costs about 12-thousand dollars to buy and install. It’s hoped the network of weather stations can be expanded so there’s one in every county, but for now, a dozen will give a good snapshot of drought conditions to help farmers manage their risks. “If you see that the weather station received an inch of rain and the soil moisture has moved up to such and such a level from where it was at the moisture station, and you know that at your farm because of the gauge out on your post that you got an inch and a quarter, you probably did a little better,” Taylor says, “or if you got half an inch, you didn’t do as well.”
The new weather stations replace ones that have been monitoring data at the farms for more than 30 years. Taylor said the original units made up the world’s first non-military network of automatic reporting weather stations. The weather stations will also measure rainfall, air and soil temperature, humidity, sunlight, wind speed and direction. A solar collector powers the units.
