Iowa preliminary weather summary by Harry Hillaker, state climatologist, Iowa Department of Agriculture & Land Stewardship: The past reporting week began with unseasonably high temperatures with afternoon maximums in the 80s over nearly all of Iowa on Monday, Sept. 28. A cold front moved across the state late Monday and into Tuesday and was followed by below normal temperatures for the remainder of the week. Daytime highs were mostly in the 60s from Wednesday through Saturday, Sept. 30 to Oct. 3, with afternoon readings only in the 50s over much of eastern Iowa on Sunday, Oct. 4, owing to widespread cloud cover that day.
Temperature extremes ranged from Monday afternoon highs of 86 degrees at Donnellson, Lamoni, Osceola, Perry and Sidney to morning lows of 32 degrees at Estherville on both Wednesday and Thursday. Temperatures for the week as a whole averaged 1.0 degrees below normal.
Rain fell over all but a few far southeastern Iowa locations between Monday afternoon and Tuesday morning. This was the only rain event of the week. Greatest rain amounts, mostly in the one to two inch range, fell across the central one-third of the state from Monona and Harrison County east-northeastward to Clayton and Dubuque counties. The greatest rain total was a 2.73 inch amount north of Woodbine in Harrison County while no measurable rain fell at Centerville, Keosauqua and Albia.
The statewide average precipitation was 0.57 inches while normal for the week is 0.70 inches. Soil temperatures at the four inch depth as of Sunday afternoon, Oct. 4, were averaging in the mid to upper 50s statewide. However, those readings are expected to climb this coming week with warmer weather on the way.
