A shift in the weather pattern brought a more active storm track to the Midwest along with a derecho that blew through northern Iowa. The squall line left behind pockets of damaged corn and soybeans along with heavy rainfall. Many of the state’s reporting stations observed above-average rainfall with positive departures of over four inches in northern and eastern Iowa. Conditions were also unseasonably warm with a statewide average temperature of 76.5 degrees, 2.1 degrees above normal
Scattered cumulus clouds began forming across Iowa’s western half through Sunday (3rd) afternoon as highs climbed into the mid to upper 80s. Southerly winds persisted overnight as a warm front pushed west to east over Iowa, firing a wide shield of showers and thunderstorms into Monday (4th) morning. The disturbance continued through Iowa before exiting the eastern border during the early afternoon hours. Measurable rain fell across Iowa’s northern three-quarters with over 50 stations measuring at least an inch of rain. Several stations also reported more than two inches with 2.91 inches observed at Decorah Municipal Airport (Winneshiek County); the statewide average rainfall for the event was 0.74 inch. Clouds cleared as muggy conditions continued through Independence Day fireworks with high temperatures rocketing into the upper 90s south while mid 80s were reported north. Tuesday (5th) was an eventful day across the Upper Midwest as a derecho propagated over 600 miles from northwest South Dakota through northern Iowa before dissipating in Illinois.
