Iowa preliminary weather summary provided by Justin Glisan, Ph.D., state climatologist, Iowa Department of Agriculture and Land Stewardship – An active
weather pattern over the Midwest brought wetter than average conditions across much of Iowa with the state’s southeastern counties reporting totals three to five inches more than normal. The northern one-third of Iowa reported near to slightly below average rainfall. Unseasonable warmth also persisted across Iowa with the statewide average temperature at 62.6 degrees, 3.9 degrees warmer than expected.
A low pressure center continued to move through Iowa during the day on Sunday, Sept. 22, leaving measurable rainfall statewide. Totals were highest in southern Iowa, generally between 0.25 inch to 1.00 inch. Creston (Union County) observed 2.10 inches. With the cloudy and rainy conditions, high temperatures during the day remained in the mid to upper 60s.
Monday was warm and mostly sunny with southerly winds boosting daytime temperatures. Highs reached into the upper 70s and low 80s with a statewide average high of 78 degrees, six degrees warmer than normal. Overnight lows remained warmer than average, generally in the lower 60s.
Tuesday, Sept. 24, was an active weather day as a strong cold front pushed into northwestern Iowa during the afternoon hours. Highs reached into the mid 80s as a strong southerly wind pushed moisture into the state. As the cold front encountered these unstable conditions, discrete thunderstorms fired, some of which turned severe relatively fast. The individual cells eventually coalesced into a continuous band as the front propagated across Iowa. All modes of severe weather were reported with multiple reports of severe hail and straight-line winds; an observer in Holstein (Ida County) reported 1.75 inch diameter hail. There were also preliminary reports of weak tornadoes in Harrison and Ida counties. Measurable rainfall was reported statewide, generally in the range of 0.10 to 0.75 inch. Greatere amounts were observed in western Iowa with Atlantic Municipal Airport (Cass County) reporting 4.67 inches.
