Rainfall for 2012 to date has been just over 8 inches while the statewide average for this period is just less than 8 inches. Drought conditions that parts of Iowa — including northwest Iowa — are still experiencing are the result of the heat and dryness of late summer through the end of 2011. That from a report is prepared by the technical staff from the Iowa DNR, the Iowa Department of Agriculture and Land Stewardship, and the USGS, in collaboration with the Iowa Department of Homeland Security and Emergency Management Division.

Meanwhile, two Iowa-based climatologists say they’re somewhat concerned about the weather impact on Iowa’s crop-growing season. The N-W-S forecast predicts warmer than normal temperatures south of Iowa and Illinois in the extreme southern cornbelt. State Climatologist Harry Hillaker says he doesn’t want to see the warm temperatures seep into Iowa.[audio:http://www.kiwaradio.com/files/ddlongwx3.mp3|titles=ddlongwx3]
And Iowa’s May temperatures are already running about six-degrees above normal.[audio:http://www.kiwaradio.com/files/ddlongwx1.mp3|titles=ddlongwx1]
Iowa State University climatologist, Elwyn Taylor, is also worried about the long-range forecasted above normal temperatures in the southern corn belt.[audio:http://www.kiwaradio.com/files/ddlongwx2.mp3|titles=ddlongwx2]
The long-range forecast is for normal precipitation through June. Hillaker says the La Nina and El Nino influences are subsiding and shouldn’t affect Iowa’s summer weather.
