The past reporting week began with very warm and humid weather and frequent rainfall. Rain fell nearly statewide from Sunday (6th) evening into Monday (7th) morning with very heavy rainfall over portions of central and south central Iowa. This was followed by another statewide rain event from Monday (7th) night into Tuesday (8th) morning with the heaviest rains concentrated over southwestern areas of the state. Wednesday (9th) and Thursday (10th) were not quite as warm. Light rain fell over the northern one-third of Iowa and far western portions of the state from Wednesday afternoon into Thursday morning. Rain also fell nearly statewide on Thursday into Friday (11th) morning although amounts were mostly light excepting a few localized areas of around an inch of rain across the east. Dry and much cooler weather prevailed over the weekend. Rain totals for the week varied from 0.11 inches at Hampton and 0.14 inches at Castana (Monona Co.) to 6.35 inches at Bagley (Guthrie Co.), 5.53 inches at Lake Rathbun and 5.15 inches at Bedford. The statewide average precipitation was 1.38 inches while normal for the week is 0.82 inches. Daytime highs climbed into the eighties in many areas from Monday through Thursday with Burlington, Donnellson, Le Claire and Muscatine reporting the highest temperatures with 89 degree readings on Monday (7th). Meanwhile, temperatures fell to 37 degrees at Sheldon on Saturday (12th) morning and 38 degrees at Elkader, Manchester and Stanley on Sunday (13th) morning. Very cool late week weather just barely cancelled out the very warm start to the week with temperatures for the week as a whole averaging 0.4 degrees below normal.
