Widespread rain returned to Iowa for the first time since September 29. Showers and thunderstorms brought rain to about the southeast one-half of the state on Tuesday (20th) with greatest amounts of an inch or two across east central Iowa from Williamsburg to Muscatine. Another area of showers and thunderstorms dampened about the southeast two-thirds of Iowa on Wednesday (21st) morning with greatest rain amounts of around one-half inch in the Ames area. Finally, rain moved into western Iowa late Thursday (22nd) night and exited northeast Iowa Saturday (24th) morning. Rain fell statewide with this last system with greatest amounts over far northwest Iowa where amounts of an inch or more fell. Greatest rain totals for the week occurred in northwest and east central Iowa with 2.76 inches at Sheldon and 2.25 inches at Iowa City. The northeast corner of the state saw the least rain with 0.13 inches at Dorchester. The statewide average precipitation was 0.63 inches or just slightly more than the weekly normal of 0.56 inches. Meanwhile, temperatures were well above seasonal normals from Monday (19th) through Friday (23rd). Seasonal temperatures returned at the week end. Extremes ranged from afternoon highs of 82 degrees at Red Oak and Shenandoah on Monday (19th) to morning lows of 28 degrees at Battle Creek, Decorah, Newton, Stanley and Webster City on Sunday (25th). Temperatures for the week as a whole averaged 8.1 degrees above normal. Soil temperatures as of Sunday (25th) were averaging near 50 degrees across northern Iowa to the mid-fifties over the south central and southeastern portions of the state.
