Warm and humid conditions prevailed for most of the past week although Tuesday (11th) and Wednesday (12th) brought cooler weather to much of Iowa. Temperature extremes varied from a Wednesday morning low of 50 degrees at Elkader to a Saturday (15th) afternoon high of 92 degrees at Bellevue. Temperatures for the week as a whole varied from just below normal over far southeast Iowa to about three degrees above normal across northern sections of the state. The statewide average temperature was 1.5 degrees above normal. Most of the reporting week’s precipitation came on Sunday (9th) evening and night and primarily fell across the northwest two-thirds of the state. There were also some localized showers over east central Iowa on Monday (10th) afternoon, as well as some light rain over portions of the northeast and southeast corners of the state on Friday (14th). Rain totals varied from none at scattered locations across southern and eastern Iowa including Lamoni, Fairfield, Iowa City, Cresco and Fayette to a 2.72 inch total at Spirit Lake. The statewide average precipitation was 0.28 inches while normal for the week is 0.98 inches. This was the Iowa’s driest reporting week in 15 weeks (week ending May 3). However, heavy rains fell over portions of the northwest one-third of Iowa Sunday (16th) evening into Monday (17th) morning, but largely fell too late to be reflected in this week’s statistics.
