It was an energetic day of weather across Iowa and beyond on Wednesday. The day started with a strong complex of storms diving south during the early morning hours and producing damaging winds along with significant rainfall. This complex greatly altered the placement of the afternoon round of severe storms with the most damaging staying south of Iowa. A few storms were able to develop over far northeastern Iowa during the afternoon hours and even likely produced a significant tornado. The storm complex was associated with a low pressure system that was more typical of April than mid June for Iowa. The pressure was very low for June as shown by the featured chart of top 10 lowest pressure altimeter values for Mason City (NC Iowa). Yesterday comes in as the fifth lowest date since 1940 during June!
