Episode narrativeepisode_narrativeRainfall dominated the story on the 19th and into the 20th as western Iowa found itself in a favorable setup for sustained moderate to briefly heavy rainfall. Initially, showers and storms along a weak frontal boundary as part of a larger upper level trough. Showers continued throughout the day, especially as a more organized surface low moved towards southern Iowa out of eastern Kansas. Given the area's location in relation to the surface low, severe weather was of little concern with nominal to moderate CAPE at best and little other support for organized storms of any kind. Precipitable water values were in excess of 1.5 inches through the 19th and well into the 20th, helping produce efficient and continuous rainfall as the upper level trough and surface low slowly moved through. While truly heavy instantaneous rainfall was relatively hard to come by, the sustained light to moderate rainfall produced heavy rainfall values in excess of 4 inches in a number of locations, including values as high was 5.8 inches reported.
