The primary weather event of the past reporting week was the widespread precipitation event occurring from Tuesday (5th) morning to Wednesday (6th) morning. This event came in the form of rain over most of Iowa and two to four inches of snow over the extreme northwest. Heaviest rain fell in northeast Iowa where numerous locations received over one and one-half inches. Otherwise there was some light rain from south central into northeast Iowa Monday (4th). The rest of the week was dry. Postville reported the most rain with 1.86 inches while the extreme northwest and southeast corners of the state were the driest with 0.33 inches of rain at Keokuk and 0.26 inches of precipitation (in the form of 3 inches of snow) at Rock Rapids. The statewide average precipitation was 0.91 inches while normal for the week is 0.52 inches. Thanks to another widespread precipitation event on October 30, this marks the first time that Iowa has recorded consecutive wetter than normal weeks since late May. Temperatures for the week as a whole averaged 0.6 degrees below normal. Daytime highs were mostly in the 40’s from Tuesday through Friday over northern Iowa but occasionally climbed into the 60’s over portions of the south on Friday and Saturday. Temperature extremes varied from a Thursday morning low of 15 degrees at Sioux Center to a Friday afternoon high of 67 degrees at Red Oak. Finally, soil temperatures as of Sunday (10th) were averaging in the upper 30’s northwest to mid 40’s southeast. Snow-covered ground impeded fieldwork over the far northwest from Tuesday until the last of the snow melted on Friday morning.
