DES MOINES, Iowa (AP) — Iowa officials are recruiting people to help monitor the state’s weather as part of a volunteer network. The state Department of Agriculture and Land Stewardship says data on rain, hail and snow that’s collected by volunteers will be used for flood forecasting, scientific research and general weather interest. The department’s state climatology office works with the National Weather Service in Des Moines to make sure the data is immediately available for free online.
Interested volunteers just need a four-inch diameter rain gage and a suitable location for the gage.
The Colorado Climate Center established the volunteer network in 1998, and it’s available in all 50 states and Canada. Iowa joined in 2007 and has more than 300 registered volunteers.

Parts of Iowa will be in for a coating of white by tomorrow (Thursday) afternoon as a wintery storm system is headed our way. Meteorologist Kevin Skow, at National Weather Service office in Johnston, says the front will be bringing very low temperatures and plenty of precipitation. Skow says, “It’s going to start out as rain across our area but then colder air will work in from the northwest and cause that rain to change over to snow, especially across the northwestern half or so of Iowa tomorrow evening.”
A wide section of Iowa could have a blanket of white snow before the weekend arrives. “In general, we’re expecting anywhere from one to three inches, with the highest amounts in northwest Iowa closer to the Sioux City-Sioux Falls area,” he says. While it’s still fall for another month, this storm will definitely feel like winter, as the front may bring in the coldest air of the season so far.
Skow says, “Cold air will work in here on Friday and Saturday and highs on Saturday will only be in the mid-teens to mid-20s across Iowa and the lows on Saturday night will dip down into the single digits above zero with some areas even getting below zero.” Daytime highs by early next week will be back closer to normal in the 30s to low-40s across Iowa.
With the chance of accumulating snowfall to occur in Clarinda later this week the Clarinda Police Department is reminding the citizens of Clarinda about the emergency snow ordinance. The ordinance states that: “No person shall park any motor vehicle or other apparatus upon any street of the city that will obstruct the removal of snow when there has been an accumulation of two (2) inches or more. Any vehicle left parked on any street in violation of this ordinance may be impounded, and the registered owner of the vehicle will be subject to a $15.00 parking fine, and payment of all applicable towing and storage fees in order for the vehicle to be released.”
