Episode narrativeepisode_narrativeA complex weather situation was in place during the overnight hours of the 2nd into the morning of the 3rd. A warm front was positioned to the south of Iowa. Meanwhile, a secondary cold front dropped into the north central U.S. and stretched from eastern Montana into southern Minnesota. The upper flow was northwest and quite conducive for MCS development as considerable moisture transport took place over Iowa. Initially, an area of thunderstorms formed over south central Iowa. The storms remained below severe limits as they tracked east-southeast out of the CWA. A strong thunderstorm complex developed over western South Dakota during the night and propagated southeast, along with the upper air northwest flow, into Iowa. The MCS became linear in nature as it moved out of northwest Iowa into the central sections of the state. Very heavy rainfall resulted in flash flooding in several counties, with urban street flooding along the length of the line. Rainfall rates of one to two inches in one half hour or less were reported. A few areas received 2 to 3 inches of rain. Appanoose County was quite hard hit with water flowing over the roads two feet deep. The main severe mode of the system was the high winds. There were numerous reports of 60 to 70 MPH winds. The entire length of the line produced 40 to 50 MPH winds however. Hail was somewhat limited as the freezing level was over 14,000 feet. Following the passage of the line, high winds became a problem as a wake low developed. Winds gusted to 58 MPH in Story County at Colo and wind damage was reported in Polk County at Bondurant.
Event narrativeevent_narrativeStreet flooding was reported in Ottumwa. A number of intersections and low lying areas were under water, including the intersection of Jefferson and Main.
